In alphabetical order, Buren, Cortebert, Cyma, Ebel (2 case types), Enicar, Eterna, Fontainemelon, Grana, Lemania (central seconds and sub seconds), Leonidas, Moeris, Reconvilier, Record, Revue (Cal 57 and Cal 59), Rotary, Timor, Unitas. 17 manufacturers, and 20 case and movement types.
The Army Trade Pattern (ATP) series of watches was made available at the commencement of WWll via a MoD contract with Swiss watch manufacturers in 1939. In an effort to demonstrate neutrality, the Swiss supplied almost identical watches to Germany, but with black dials. Some of these corresponding D-H watches are discussed below.
Leading into WWII the ATP watch was issued to soldiers and was supplied to the Ministry of Defence (MoD) by 17 Swiss suppliers, under brand names Buren, Cortebert, Cyma, Ebel, Enicar, Eterna, Font, Grana, Lemania, Leonidas, Moeris, Reconvillier, Record, Revue, Rotary, Timor, and Unitas. Ebel, Revue and Timor produced 2 types of watch, so about 20 watch types were in the ATP series. The catalogue number was VA/VC. 7471.
Most had the following characteristics:
15 jewelled movement with a round waterproof case about 31mm diameter in stainless steel or nickel chrome, white dial with railroad track chapter ring marked in minutes, luminous index spots, and broad lumed baton hands and a silvered subsidiary seconds register, with an accuracy +/- 30 seconds per day. They all were to have fixed bars between lugs.
On the dials only the Buren had a single sided railroad chapter ring, and only the Ebel (poire squelette) and Reconvilier (Dauphine) hands varied. The subseconds dials and hands varied more.
133,600 ATP watches were purchased at an average price of £3. After WWll many were decommissioned, and some continued in service. In a decommissioning document they were described as :

The ATP watch was deleted from the stores list by an amendment dated February 3, 1957, when the W10 watch designation was introduced.
Many ATP watches are engraved Bravingtons, indicating they were decomissioned stock.
A few have replacement dials, either sterile or signed, and Armand and GMT are such signed examples.
The MWR forum user Bobsy has listed ATP sales in the past 4 years, which gives some idea of availability of the 20 watch types.
The watches were supplied to the MoD without straps. They were then fitted by the MoD with open ended leather straps with folded metal butterfly clips as seen on the Grana ATP below.
The engraving on the case back was generally the pheon, together with A.T.P. and an issue number, although the issue number was sometimes missing.
Leather straps often perished in tropical conditions and canvas straps were used, particularly in Asia and the Pacific. The 44 pattern webbing was designed and issued for tropical conditions, and the AF0210 strap was issued in 1945 as part of this Jungle Warfare Equipment.
Below is a rare combination. The hard to find Reconvilier ATP watch on an original WWII period AF0210 canvas strap. ATP watches on AF0210 straps have recently sold on ebay with an approximate strap value of over $400. The strap fitted quickly and easily under the fixed bars of the ATP watch.
The various ATP watches are shown individually below on A.F.0210. straps.
The Buren ATP is reasonably rare, being 7th in the list of 20 watches above. The watch serial number was engraved on the case (14xxxx). The case number was 1021 and was engraved between the lugs, easily seen as the watch has spring bars. The watch had pencil hands with syringe tips, and a stick sub seconds pointer. The case back was a 6 slot screw fitting.
The 10.5″‘ Buren 410 movement is used with a sub second dial, and the crown wheel is engraved Buren Grand Prix. The Buren 411 movement has a sweep second hand.

The three fingered Buren Cal. 410 movement and retaining ring above with 6 slot case back. Below, case engraved 1021 between the lugs as well as inside the case back.
The Buren is often seen engraved Bravingtons.
Below is a MoD redial Buren, with a simplified signature, dial and sub-dial, and a Bravingtons case, shown on a 6B/2617 strap.
Below is a Breguet style MoD redial.
Buren also produced a German D-H watch, with a black dial in WWII, shown on the right below. (D stands for Dienstuhr (Service Watch) and the H = Heer (Army)).
Just as there were desired characteristics for the ATP watch, with a few exceptions the basic D-H wristwatch had the following characteristics:
About 34mm outside case diameter.
Black dial with luminous numbers and hands
Fixed bars, either steel pins or cast as part of the case. There are a few exceptions with spring bars.
Threaded case back with 6 wrench slots
15 jewel movement with shock resistance.
The cases are mostly chrome plated brass, some are all stainless steel.
Of the various manufacturers, those who did not make their own movement mostly used the A.S. 1130 movement produced by Anton Schild, of Grenchen, and consequently some people call the A.S. 1130 the “Wehrmacht movement.”
The Buren D-H watch was slightly larger, and also used the cal 410 movement, and the 12″‘ Buren cal 462 movement.
Buren cal 462 below with 12″‘ stamped below the balance wheel.
Buren was eventually taken over by Hamilton.
The Cortebert ATP is mid table in the above chart, 11th of 20 ATP watch sales.
The case is stainless steel with chamfered lugs, with a scalloped edge stainless steel back plate numbered 8126 or 8135, and an internal dust cover. Serial numbers are 29xxx, 3xxxx, 7xxxx, and Pxxxx, but sometimes this is absent.
The original dial has a railroad track chapter ring, and a flat topped 3 and an open 4. Some have 2 lume dots at 3 and 9. The watch has an unnumbered railroad sub seconds dial, with a stick pointer.
Later MoD redials have open or closed 4, sometimes a closed pregnant 4, curved 3, sometimes an open 9, and a sub seconds dial with tick marks, and are sometimes found with a sterile dial. Rarely Cortebert is in capitals.
Some Cortebert, Enicar, Font and Grana ATP watches have been re-issued marked 6E/385 with an Axxx serial number for the RAF.

And a sterile dial, a MoD redial with a pregnant 4 and a bold font.
And a sterile dial with lumed numerals.
The movement was the 15j Calibre 665, with CORTEBERT *** on the ratchet wheel. Some models had a dust cap rather than a retaining ring holding the movement in place. The case back was stainless steel with 8135 stamped, and with a scalloped edge. The inside case back reads Modele Depose xxxxxx.
Cal 665 movement with 2 Cortebert ATP watches, on a 16mm 6B/2617 strap and an olive green AF0210 strap.
More rarely, the case back can also be marked Waterproof Stainless Steel 8126 Antimagnetic. This was an earlier model series with 29xxx and 3xxxx serial numbers. No dust cover.
Post war, the Cortebert Sport was issued with 8126 and 8135 model numbers, and a screw back with 6 notches. Cortebert was eventually taken over by Omega.
The watch is the smallest ATP watch at 29 mm diameter, and the case is stainless steel numbered 8983-xxxx on a 4 notch case back. Serial numbers are 48xxx to 51xxx. The Cyma ATP is rarely seen, but not because it is small, being 3rd on the chart above.
The dial has bold font numbers, and the sub dial has concentric circles and a tadpole shaped hand. The 15, 30, 45 and 60 are placed radially on the sub dial.
Cyma ATP on A.F.0210.® olive green strap.
The engraving 8983-xxxx on a 4 notch case back.
Below is a CYMA and a CYMA MoD redial. The latter has fewer lume dots at 3,6,9 and 12. The numbers are not in bold, with a flat topped 3 and an open 4, and the sub dial is simplified, with the 5 and 7 cutting into the subdial.
Several examples exist of a “downgrade” of the black dial WWW Cyma watch to the ATP standard as shown below. On the other hand, various ATP watches have been “upgraded” to WWW standard. The case back has either 4 or 6 notches.
The movement was Cal 162 with sub seconds, (Cal 166 was the sweep seconds model).
Ebel had 2 ATP models, both with a 32mm diameter stainless steel case with either with a push through back or a later 6 slot screw back.
The watch was the only ATP watch to have poire squelette or cathedral hands. Some dials have 3 dots at 6, and the sub seconds dial has at least 2 versions.
The EBEL sometimes has a sterile dial.

Subdial variations include radial 15, 30, 45 and 60 above and horizontal 10,20,30,40,50, and 60 below.

The dial is usually as above, but variations exist , with the Ebel E being seen, and sterile dial.
Below is the push through case. The engraving of A.T.P on the push through case sometimes differs from the engraving on the screw down case which is either A.T.P. or ATP with no serial number.
The push-through Ebel serial numbers are mostly in the 34XXX-48XXX range, with some in the 90XXX range.
Here is an Ebel push through re-engraved as a HS11 watch.
The screw-back versions are marked A.T.P. and numbered in the F0XXXX range, or have ATP and no serial number.
The Calibre 99 movement was derived from the Cal 232 Aurore-Villeret movement. The inside case back reads Brevet, Acier Inoxydable, 999901, and is stamped 1018.
Konrad Knirim’s book shows a simplified MoD redial and replacement hands.
Another MoD dial style, with a different sub-dial.
Some ATPs saw service in India, and are marked PXXXXX, or P-1 to P-13 on the case back, inside and out. Here is an Ebel ATP example. Inside case back marked 999901, with the issue number marked inside.
Some Pxxxx series examples have a black dial, shown here with replacement hands also.
Ebel is now owned by the Movado group.
The Enicar ATP, on an olive green A.F.0210.® strap above, is reasonably common and comes in a stainless steel case with scalloped back, and can be either sterile or more rarely signed Enicar. Also, it can be 15 or 17 jewels, with the AS984 calibre movement. The hands are syringe style, some with long needle points.
Enicar ATP movement, marked 17 jewels. Scalloped edge case back. Inside case back marked JF. Dial is a MoD redial.
As mentioned above, Enicar ATP’s have been noted as being re-issued as 6E/385 with an Axxx serial number for the RAF.
Serial numbers are Fxxxx, 4xxx or ( )xxxx commencing with 4, 5 or 9.
The case back is stainless steel, scalloped, and marked either ENICAR STAINLESS STEEL with a serial number or BREVET+154571 with the initials JF (Jean Finger). The cases of the latter have drilled lugs.
The dial on the left is a MoD redial, with a sub-dial having a double railroad track, and marked radially 10, 20, 30, 40, 50, 60 as can be seen in sterile redials on other manufacturers. The right hand sub-dial is marked with numbers parallel to the 9-3 axis of the watch.
Another MoD redial with tagged fonts, and a sterile dial.
Eterna, well known for their WWW watches also supplied ATP watches.
A few Eterna ATP watches have been found with both black and white dials, mostly black and a central seconds sweep hand. Black dials and central seconds are inconsistent with the ATP characteristics, but enough Eterna ATP watches exist to conclude that about 600 may have been made from the known serial numbers in range 144xxx.
Eterna ATPs are listed in the VAOS in 1954 and 1956, and there is no doubt that a few were issued.
Below is one Eterna ATP case back, and a black dial Eterna, with a central sweep second hand. The movement is the 14 ligne Eterna 852S. 10.5 ligne Eterna 600S movements, and 11.5 ligne 1020S movements have been seen. Eterna have confirmed supplying the British Army in about 1940, but the variety of styles, and high serial numbers and movements used could indicate supply later in WW2 of the entire stock from a retailer.
Eterna 852S movement above.

The Eterna 1020 movement is seen in this 1943 advertisement.
Font (Fabriques d’Horlogerie de Fontainemelon, (FHF))
The Font ATP is relatively rare and has a stainless steel case with chamfered lugs, and with 6 notch screw back stamped STAINLESS STEEL and a sterile dial. The dial has an elongated 4, and an open 9, and the sub seconds dial is numbered horizontally 15, 30, 45 and 60, with a stick pointer.
Font ATP watches have been noted as being re-issued as 6E/385 with an Axxx serial number for the RAF.
Fontainemelon ATP on A.F.0210.® strap, and a RAF style version of the A.F.0210.® strap.
The movement is Cal FHF 150, and like the Buren ATP above, the case has spring bars. Serial numbers are 10xxxx or 11xxxx usually with the ATP and pheon stamped on the case, and more rarely Pxxxx with engraving.
A rare combination below, a Font ATP on an original AF0210 strap.
The Grana ATP is the 4th most common ATP watch , unlike the successor, the Grana WWW, which is scarce. It has a 32mm brass chrome plated case and a six-notch stainless steel threaded case back stamped on the inside either Grana 1516 or the later issue 1735. This number is also engraved between the lugs.
The dial may be signed or sterile. The 3, 9 and 12 are in bolder font on the later dial.
The Grana had two original dials.
The first model had 1516 engraved between the lugs, and on the inside case back, and the lume had 2 dots at 3 and 9, and a vertical lozenge and 2 dots at 12. The movement reference number, KF320, is stamped at 3.
The inside case back of the first model is shown below, with 1516 stamped underneath the serial number, and the movement number KF320 stamped at 3 o’clock. The early series Grana models have inside case back serial numbers 32xxxx.
The outside edge of the case back for this model is either square or stepped, with 6 notches. An unusual serial number on the case back beginning with J
The second (later) model is seen with WWW or ATP on the case back, and is engraved 1735 in the same places.
The outside edge of the case back is chamfered, the 6 notches are deeper, and the military service number begins with an M.
Grana case back for 1516 and 1735 issued watches. The former has the movement signed at 3. The latter case back is chamfered at the edge. Image courtesy MWR forum member : isologue
The model 1735 dial has bold numerals at 3, 9 and 12, with only a lume lozenge at 3 and 9. The movement reference number is stamped at 4, but in reverse to the black dial WWW model. The Grana inside case back serial numbers are 46xxxx. The sub seconds pointer should be a stick pointer.
Below are sterile Grana MoD redials, one with an open 9 and a different sub seconds dial, and the other a pregnant 4.
The movement is a Kurth Freres/Certina KF320 with no magnetic protection, and the movement number stamped at 4 on the second model.
Cortebert, Enicar, Font and Grana ATP watches have been re-issued marked 6E/385 with an Axxx serial number for the RAF.
Black and white dial Grana watches have been produced with ATP and WWW engravings on the case back. Shown below is a Grana with a black dial with pheon, and ATP engraving. Serial numbers Mxxxx are often seen on these models.
The black dial Grana is shown below on an AF0210 strap. This has a pheon on the dial, but differs from the WWW black dial Grana. The white dial WWW Grana does not have the pheon on the dial and is the model 1735 dial with bold numerals at 3, 9 and 12, and with only a lume lozenge at 3 and 9.
This type of Grana W.W.W./ATP case back has been seen several times. The 1735 style case has been seen with W.W.W. on the case back in the later series of Grana ATP watches, together with the chamfered edge on the case back. The rare Grana W.W.W. watch also uses the KF320 movement, but this is flipped on the signed movement.
Below is the white dial Grana W.W.W. movement and case back.
And finally, a Certina Grana dial, and another MoD redial.

This is another common ATP sub seconds model with characteristic slim syringe hands, but uncommonly, the dial is sterile. The case is made of 31mm steel with a six-notched screw case back. However, there is also a Lemania ATP with a centre seconds sweep hand which is almost the rarest of the ATP models, made perhaps because Lemania needed produce more watches than the prior sub seconds model, later in WW2. This watch was issued in 1945-6 and is slightly larger than its subsidiary seconds ATP predecessor, and has been seen with a WWW overstrike.
Lemania sub – seconds watch. Some watches have double lume dots at 3 and 9 as above.
Another dial exists, with ghost numerals at 3, 9 and 12, and a more tadpole like second hand. The 15 seconds markers on the sub dial are horizontal, not radial. The inside case back is stamped 6078-1.
The central seconds watch is much rarer. It has a flat topped 3, and the railroad chapter ring is broken into 1/5 seconds.
shown below with 4 other Lemania ATPs.
Below is a Lemania MoD redial with an open 9 and radial seconds markers, 10, 20, 30, 40, 50 and 60.
And a MoD redial with ghost numerals.
Also, rarely the dial is signed. This is usually on Qxxxx numbered watches with drilled out lugs.

The Lemania ATP has a Tissot A27 caliber, which would also be used in the later WWW watch. The case back is engraved in concentric circles WATERPROOF, NON MAGNETIC, SWISS.
The case is chrome plated, and the inside case back is stamped, Fond Acier Inoxidable 6078-1, and a watch serial number.
The MoD serial numbers are Qxxx, Qxxxx and 12xxxx.
Below is a 6E/385 version with ATP struck out, and an A and 6E/385 added to the case back.
The Lemania centre seconds has also been seen as a WWW overstrike. The manufacturers case numbers of the Lemania centre seconds are in the range 5xxx to 6xxx indicating about 1-2000 were issued. Below is the case back of a Lemania WWW.
Serial numbers for the central seconds watches are 37xxx to 42xxx.
The movement of the Lemania CS ATP watch and the Lemania chronograph are based on the same movement, the Cal 27. The only difference with the ATP version is that the mechanism was never equipped with any of the wheels and levers associated with the more complicated chronograph.
Lemania used the Tissot CalA27 movement in the sub-seconds watch.
The Leonidas ATP has a chromed brass case of 31mm, with a threaded stainless steel case back with the usual six notches, with the case number 1018 inside the stainless steel case back. The case number 1018 is also between the lugs, and it has spring bars, both design elements like the Buren.
The dial is usually signed, although there are sterile examples. It has SWISS MADE on the dial between 5 and 7 inside the chapter ring, and a flat topped 3 and open 4. The sub-dial has a railroad ring with ticks at every 5 minutes, and a stick pointer.
Above, left the signed Leonidas ATP, and right, a sterile MoD redial Leonidas.
Inside case back marked STAINLESS STEEL BACK, SWISS and stamped 1018. 1018 stamped between the lugs as above.
6 notch case back with deep grooves marked ( )xxxx beginning with 10 to 12 or 41.
The Leonadis ATP uses the 15 jewel Fontainemelon FHF 186 calibre movement without magnetic protection. 8 tag retaining ring.
Leonidas is now part of Tag Hueur group.
Like the Eterna, a few small diameter sub and central seconds Mido ATP watches exist. These do not conform to the white dial sub seconds register definition of an ATP watch, but enough exist to raise the possibility that supply pressure in WW2 led to other Swiss watch manufacturers supplying ATP watches.
The case back is scalloped and carries UWC in a triangle.
The Moeris ATP is the easiest of all ATP watches to find. Poor chrome makes specimens look in very bad cosmetic condition, but the case back is screw in stainless steel with six notches. The case is 33mm diameter, the largest of all the ATP watches. The dial can be found signed or sterile.
Below, dial with Shock Absorber above the seconds sub-dial, watch on an original A.F.0210 strap, and dial, left, with nothing above the seconds sub-dial on an original 6B/2617 strap from 1954, thought to be an earlier model.
The case back is easy to recognize, and identifies unsigned copies, with STAINLESS STEELBACK SWISS MADE, or STAINLESS STEEL BACK WATERPROOF in an outer circle and 6 notches. The serial numbers are Mxxx, Pxxxx, 5xxx, 7xxx, 8xxx, 11xxx, 5xxxx and 6xxxx.
The movement is the Moeris Cal 10.5 (the Moeris, 15 jewel, manual wind 10 1/2 ligne movement), with some later models having shock absorber on the ratchet wheel, as shown below. This may or may not be written above the sub seconds dial.
Moeris movement and case back, WATERPROOF with and without a serial number.
This case back can also read SWISS MADE, in this case with no military engraving.
The Moeris was sometimes redialled by the MoD with a simplified dial. The dial in the middle below has a tagged MOERIS signature, and has narrower numerals, an open topped 4, a flat topped 3 and a closed 9, here shown with 4 other original dial Moeris ATP watches. The sub seconds dial is a simple railroad track, with no numerals.
A black dial version has been seen, and a black dial MoD redial version, engraved H.S.11, is shown below, with the same dial as the redial above, a flat topped 3 and open 4, but the signature is not tagged.

Here is another MoD redial, issued as a Moeris T, and also engraved H.S.11
Another simplified MoD redial is shown below without the railroad chapter ring, an open 9 and a pregnant 4, and a simplified sub seconds dial. Second hand is a replacement.
The Moeris D-H also has the Moeris caliber 10.5 lines, 15 rubies, Incabloc shock-proof balance axis, 36 hours power reserve movement. The crown wheel signature is sometimes BRUCHSICHER, but otherwise the movement is identical to that in the ATP watch.
The rarest ATP watch is also the largest with 33mm diameter plated case. The dial is unsigned but is clearly distinguished by Dauphine hands, the only ATP watch to use these, and the pregnant 4. The movement is the Reconvilier 120 caliber with magnetic protection.
Reconvilier with the 1954 6B/2617 strap, the first NATO strap designed by the RAF. (Gloster Meteor still in service in 1955).
Below are 2 Reconvilier ATPs, one on the original 6B/2617 strap from 1954, and the other on an original A.F.0210. strap from 1945.
The case back is a 6 notch screw in stainless steel with a chamfered edge to the back, marked 1xxxx or 2xxxx.
The movement is the Reconvilier 120.
The Record ATP has a rare black dial as well as a white dial which can be signed or sterile. The unsigned watch can be distinguished easily as it features an open 4, flat topped 3, and the sub-seconds dial is an unnumbered rail track.
The case back is a 6 notch screw back, with no engraving other than the pheon, ATP, and the serial number..

The Revue Cal 57 is the second most available ATP watch. The Revue 57 had either a thick crown, or a waisted crown and was only 30mm diameter, with mostly plated case, but sometimes stainless steel.
The Revue 59 was larger at 33mm and had a plated case.
Both dials were sterile.
The Revue 59 on the left on original A.F.0210. strap and the smaller Revue 57 on Bonklip strap.
The Revue 57 had a unique distinctive font for the hour numbers, with a flat topped 3, and tagged 1’s, and sometimes a unique waisted crown.

This watch has a waisted crown, and the bottom left hand lug is stamped S. The Cal 57 is stamped on the movement.
The Revue 59 has bold numbers at 3, the open 9, and 12, and is 3mm larger than the Revue 57.
Above is a Revue 59 on a 6032 strap from 1945 and a Revue 57 with a MoD redial, on a 6B/2617 strap from 1954.
If the case back has a serial number it is of the type Q3xx, Qxxxx, 3xxxx, 4xxxx, 9xxxx, or 12xxxx
Stainless cases were in the higher serial number series, and plated cases were often in the Q series.
The Revue 57 was produced with both plated and stainless steel cases. The left lug below right has C for nickel chromium plating. S was stamped for stainless steel. The inside case back reads either Nickel Chromium Plated, Stainless Steel Back, or just Stainless Steel, for C and S stamped watches.
Anecdotal evidence seems to suggest that the earlier production runs were plated and the later ones had stainless steel cases. A castellated case back was used.

The corresponding D-H watch was a Revue Sport with Cal 59 movement.
The Rotary ATP is rare. It is actually the largest at 33.5mm and the caliber, like that of the Enicar, is based on the AS984 without antimagnetic protection. The signature on the dial can be curved or flat.
The curved signature RotAry with block style numerals, and long thin rectangular syringe hands with short needle points. The sub dial is marked 10, 20, 30, 40, 50, 60 in horizontal style.

The Timor ATP is common with a plated case and stainless steel case back. About half use a slotted case back, and half a scalloped back. It uses a caliber 99 (99B Timor, based on Peseux 190) without antimagnetic protection. Timor, along with Grana, Moeris and Record, also had a rare black dial.
This is the only ATP with waterproof on the dial, positioned above the seconds sub-register. The dial has bold numerals, and a large railroad track chapter ring. The hands are pointed syringe style. The dial is also seen with rectangular lume at 3, 6, 9 and 12 (with a closed 9) and two dots at 3 and 9.
The dial can also be sterile, with a railroad track sub seconds register broken into 10 second intervals.

Various serial numbers are used, but the serial number can be missing, or Pxxxx, and ( )xxxx, with 1, 2, 6, 7, 13, 14, 16, and 17.
Scalloped case back, sometimes with 15600 case back number. Left hand case marked HS.11
Slotted case back, with notches just meeting the flat of the case back.
A variety of engravings have been seen, including the WWW designation. The 6E/385 overstrike is officially described as Army watch Ref. VA/VC. 7471. For R.A.F. Mountain Rescue Units.
It is among the largest with its stainless steel case 33mm diameter, stainless steel case back with six notches and 63717 case number with serial numbers between 9xxxx and 10xxxx. Pencil hands with a very thin minute hand.
The movement is the Unitas 173 calibre.
Striped Unitas 173 movement and BRAVINGTONS case back below, this has long notches and 63717. Many Unitas ATP’s are engraved Bravintons. The calibre 173 movement is capable of hacking, and is also used in the ARSA D-H watch.
The case back is most commonly engraved Bravingtons (in cursive) as below, and the back then has 6 short notches. 63717 case number also.
Below two MoD redialed watches, one sterile, and the other with a Unitas signature without the lines..
The ARSA D-H watch and the Unitas ATP watch used the same movement.
The German DH watch on the left below has 15 jewels, (15 rubris), and is signed ARSA, (A Reymond Ltd).⠀Beneath the ratchet wheel it is marked 173.
The British ATPs on the right are signed UNITAS, and 15 jewels,⠀and the central watch is also marked under the signature with 173.
Early serial number ARSA D-H watches have G.R. engraved inside the case back, and later serial numbers, F.T.
As mentioned above, some ATP watches went to other branches of the military. A selection are shown below. A sterile dial Grana, a Lemania, a Cortebert all re stamped 6E/385 and a Moeris T MoD redial re stamped HS11

The Vertex Revue 59 movement is used in the Revue 59 ATP as discussed above. Some call this watch the Vertex ATP, as the dial is sterile, and the movement is marked Vertex.
The Vertex WWW has been seen downgraded to an ATP standard. This is unusual, but has been seen above with the CYMA ATP.
There are a few Wyler ATP watches that were possibly made for the MoD during a supply shortage, like Eterna and Mido ATP’s. Again these do not conform to the definition of an ATP watch.
Below is a Wyler Special, about 29mm diameter with 14.6mm lug width case back engraved ATP with pheon. Centre seconds, black dial, shown on a 6B/2617 strap.
Another Wyler, again centre seconds, black dial.
And a centre seconds white dial Wyler Extraflat engraved ATP and Bravingtons.
