MoonSwatch Nylon Deployant Strap — FKM Reinforced Notches

A lightweight, breathable alternative to rubber — our nylon strap with FKM reinforced notch holes combines the comfort of woven nylon with the durability of FKM rubber at every stress point. The deployant clasp gives a clean, secure closure without the daily threading of a pin buckle. Shown here on the Mission to Moonphase New Moon (Black Snoopy) — also pairs well with Mission to the Moon, Mercury, EarthPhase, and any dark-cased MoonSwatch.

The nylon weave sits soft against the skin and dries quickly after washing or sweat, making it a popular choice for warm weather and active wear. The FKM reinforcement at each buckle hole prevents the fraying that standard nylon straps develop over time — the most common complaint with fabric straps, solved at the design stage.

The deployant clasp opens flat for easy on/off and distributes pressure evenly across the wrist. No more threading the strap through a pin buckle every morning. Once sized, it clicks shut in one motion.

Available in Black/Grey with a choice of silver or black buckle finish. Optional laser engraving on the deployant clasp — initials, a date, or a short message. A popular gift option.
