Handmade Leather Nato strap
“NATO strap” came into use as a short version of NATO Stocking Number (NSN). The more appropriate name for the “NATO” strap is actually the “G10”
Used by soldiers, they had to fill out a form known as the G1098, or G10 for short. Subsequently, they could retrieve the strap at their unit’s supply store of the same name. And used it to secure the watch to their wrists.
Since the strap was to be used by the military, it needed to be functional and fail-safe. The extra leather had a keeper at its end through which the main part of the strap passed through after it had been looped behind the watch. This created a pocket, limiting the distance the case could move. As long as the strap was passed through properly and snugly on the wrist, the case would stay exactly where it was needed.
