NATO Strap dark blue 20mm

Navy blue works everywhere, including the office

Navy is the only colourway that holds up with a suit and with swim shorts. On a blue bezel the echo is immediate; on a black dial it adds depth where black on black goes flat.

This NATO watch strap is cut from a single piece of woven nylon, to the British G10 specification. It passes under the case, bears on both spring bars, then loops back to the buckle. Marine-grade anti-corrosion stainless steel buckle and keepers. Machine wash at 30° and air dry.

Is your watch 20mm?

IWC Mark XVIII, Doxa Sub 300, Marathon GSAR, Marathon TSAR, Oris Divers Sixty-Five 40. In doubt? A caliper between the two lugs settles it in a second.

Care: machine washable

Nylon takes a 30° machine wash. That is an advantage neither leather nor rubber offers: after a day at sea or on the move, the strap comes back as new. Air dry, never on a radiator.

Few customers stop at one: see the 20mm grey NATO strap or the 20mm black and red NATO strap. To move up, look at the NATOCONCEPT bordeaux. The full width is here: 20mm NATO straps.
