This is the correct strap for a WW2 military watch, issued in 1945.
The A.F.0210. strap has a unique history, and is very hard to find, with original straps now commanding upwards of £400.
We are now manufacturing and selling faithful reproduction A.F.0210.® straps, primarily because we desired an A.F.0210. strap, and found one almost impossible to find. This has been echoed by others, credit @workingtonwatches
We have colour matched the original 16mm wide AF0210 compass strap for our 16mm wide strap (centre), and supply khaki straps in 17.5mm, 20mm, and 22mm widths (left, and in gallery photos). Our olive green strap in 17.5mm (right) is available elsewhere in our store.
