Omega Speedmaster Professional Sailcloth Strap with Deployant Clasp

This sailcloth deployant strap is built specifically for the Speedmaster owner who wears their watch properly, every day, in every condition, without compromising on how it looks on the wrist.

The Speedmaster was born as a tool watch. Worn on the moon, worn in racing cars, worn by pilots and astronauts who needed a strap that could keep up. Sailcloth matches that brief precisely. More structured and refined than rubber, more resilient than leather, and cleaner in appearance than traditional fabric. It handles water, movement and daily wear without asking anything of the wearer, and it looks right on the Speedmaster's 42mm case in a way that few materials do.

The outer layer is tightly woven sailcloth chosen for its strength and resistance to wear. A softer lining sits against the wrist throughout the day. Reinforced FKM rubber notches are integrated at every high-stress point, the areas that fail first on lesser straps, extending the lifespan significantly without adding bulk or weight.

The stainless steel deployant clasp is what separates this from every standard sailcloth strap on the market. Where a tang buckle bends and stresses the same point every day, the deployant clasp spreads pressure evenly across the wrist, opens in one clean motion, and protects the strap from the repeated fatigue that causes premature wear. For a watch worn daily, that difference compounds over time.

Available in 7 colours and in 20mm for the Speedmaster Professional Moonwatch and 21mm for larger Speedmaster references.
