Lug width

20mm - fits 19-20mm lugs

22mm - fits 21-22mm lugs

Our Deployant Nylon straps are designed with flexible nylon construction that allows each size to fit select adjacent lug widths. The 20mm strap fits most 20mm lugs and can also fit many 19mm lugs with a slightly snug feel. The 22mm strap fits most 22mm lugs and can also fit many 21mm lugs with a slightly snug feel. Fit may vary depending on the watch case and lug shape.

MonoPass™ Nylon

The pass-through nylon, without the bulk.

Military-grade nylon in a single-pass design, with silicone-reinforced adjustment notches and a deployant clasp attachment.

What MonoPass fixes

A traditional pass-through strap doubles under the watch, closes with a buckle you have to fumble, and leaves a tail to tuck away. MonoPass is a single-pass design: no second layer beneath the case, no excess length, and a deployant clasp that opens and closes like a bracelet.

That last part matters more than it sounds. A deployant stays a closed loop even when it's open, so the watch stays on your wrist while you fasten it — the same way a bracelet does. A buckle strap comes fully apart, which means balancing the watch in one hand while you thread the other end through a keeper. MonoPass goes on the way a bracelet goes on: one motion, one hand, watch never loose.

Clasp compatibility

Works with both MonoPass clasps Any MonoPass strap takes any MonoPass clasp in the same lug width — both the original MonoPass Deployant Clasp and the newer MonoPass Precision Deployant Clasp. A 20mm strap takes a 20mm clasp.

Not compatible with the Standard Deployant Clasp, which is for our 2-piece straps.

Sizing

Two widths, each covering two lug sizes:

20mm — fits 19mm and 20mm lugs
22mm — fits 21mm and 22mm lugs

Both comfortably fit wrists from 5.75″ to 8″. Your clasp needs to match your strap width — a 20mm strap takes a 20mm clasp.

An Anchor original, three generations deep

We designed the first single-pass nylon built around a deployant clasp. This is the third iteration of it, and every change came from wear rather than the drawing board. Additional silicone-reinforced adjustment notches fit a wider range of wrists without needing multiple strap lengths. The redesigned clasp attachment improves how the clasp seats and how the strap feels against the wrist.

Durable where it matters

Tough, military-inspired nylon woven for daily wear
Silicone-reinforced notches hold their shape and resist stretching out
Sits flat under the watch — no doubled layer, no tail to tuck
Machine-washable and quick-drying
