Here is a new style NATO Leather made of vintage German air force leather (We use original Luftwaffe Flight suites from the 60s)

After Elias straps made it already my idea was a very special strap for German & other military watches.
Its made of a thin sheet original air force leather, a sheet of anti stretch material which protects the strap from stretching, one sheet of genuine pig skin , ss loops, ss buckle and fully Hand made stitching around. BTW each loop is hand stitched.
Limited available from 16mm to 24mm, 320 mm long.
Thickness is about 1.8 mm they are made for fixed bars and spring bars, check your watch lug measurements

Note: Because the square ss loops are no longer available we have to switch to ss round wire loops, means new made straps will come with the ss wire loops in the future! Note: Our Nato Leather straps are made to old Military requirements, thats why Customers with small wrist size may need additional holes! We recommend to ask a shoemaker or jeweler or watchmaker because they normally have the right punching tools to punch additional holes in your new strap.
