NATO Bracelets 18mm

18 mm, the width for vintage and dress watches

18 mm is measured between the lugs of your watch. It is the width for small-diameter watches — vintage pieces from the 1960s-70s, dress watches and antique chronographs. An 18 mm nylon NATO strap fits naturally, adding robustness and character without overwhelming the watch.

Compatible watches with 18 mm lug width

18 mm fits the Omega De Ville, vintage Omega Constellation, Jaeger-LeCoultre Master, Longines Conquest, IWC Mark XI and Dirty Dozen military watches, among others. If in doubt, measure the gap between your lugs before ordering.

Sport, marine and water activities

Despite its understated look, the 18 mm NATO strap is built for active use. The marine-grade anti-corrosion stainless steel buckle and keepers resist water, perspiration and marine environments. Water-resistant, machine washable at 30° — it recovers its shape and colour without effort.

Single piece, total security

Made from a single piece of nylon, it threads under the case between both spring bars and wraps completely around the wrist. If a spring bar fails, the watch stays secured. This is the original G10 construction, the same adopted by the British armed forces in 1973.

A colour for every watch

From sand beige that echoes patinated dials, to military khaki that evokes the Dirty Dozen, to black-grey James Bond — each colour speaks to a particular watch style. The NATO strap swaps without tools in seconds.

Other widths available

For a watch with wider lugs, go straight to NATO straps 20 mm or NATO straps 22 mm. Back to all NATO straps.
