A genuine leather NATO watch strap with a Pre-V buckle, which has a curved shape and allows for a closer more ergonomic fit to your wrist. The strap is fitted with sturdy ZULU keepers, giving more robust feel when it is worn. Originally developed in the 1970s by the British Ministry of Defence (MOD), the strap was actually named G10 because of the service personnel's form they had to complete in order to receive one. Its popularity amongst other regiments led to other colours & patterns. Today, it's the well known NATO style fashionable watch strap we all wear. NATOs are durable, changeable, strong and used in sporting activities. The design (interweaving, passing through lugs) means it is also very secure.
