20mm German “Luftwaffe / Bund” Aviators Leather Military Watch Strap

These leather straps were first worn by German pilots in the second world war and many Luftwaffe (German Air Force) pilots still wear these today on the current Tutima Luftwaffe issue chronograph – see last but one image, the final image shows a 1970s Heuer German Airforce / Luftwaffe Chronograph on a Bund strap.
