OMEGA NATO Strap
OMEGA's "NATO" straps evolved from the leather and canvas straps used by British pilots, navigators and army personnel during World War Two. For safety reasons, wristwatches did not use removable spring bars to secure their straps. Their fixed bars, often soldered, were less likely to break than spring bars so there was less chance of losing the strap in conflict situations. There are three 5-stripe fabric straps with stainless steel buckles and fitted keepers; three nylon fabric straps with grey, orange or red border; a brown Novonappa leather strap; and an all-black coated nylon fabric strap with fitted black keepers and polished buckle.
