5-stripe black and grey nylon fabric strap with grade 2 titanium for the buckle and 007 engraved loop. OMEGA’s NATO-inspired straps have been influenced by some particularly robust and storied ancestors and can trace their earliest origins to the Second World War. Available in a variety of bold colours and materials, the “NATO” straps of today convey the essence of the originals while exhibiting a more contemporary and stylish look.
