Omega Seamaster Diver 300M Sailcloth Strap with Deployant Clasp

The Omega Seamaster Diver 300M takes an 18mm or 20mm strap depending on the reference. This sailcloth deployant strap is built specifically for the Seamaster Diver 300M owner who wears their watch properly, every day, in every condition, without compromising on how it looks on the wrist.

The Seamaster Diver 300M was built for the water. 300 metres of water resistance, a ceramic unidirectional bezel, and a heritage that stretches from the ocean floor to the wrist of the most famous fictional spy in cinema. From Pierce Brosnan's 2531.80 in GoldenEye to Daniel Craig's titanium No Time To Die edition, the Seamaster Diver 300M has been the defining Bond watch for three decades. Sailcloth matches that heritage 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 Seamaster's 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 at 18mm for pre-2018 Seamaster Diver 300M references and 20mm for the current generation.
