Omega Seamaster Diver 300M Sailcloth-Effect FKM Rubber Strap with Deployant Clasp
Collapsible content
Technical Specification
Product Description
The Seamaster Diver 300M deserves a strap that can keep up with it. This sailcloth-effect strap is made from FKM fluoroelastomer — the same class of rubber used in aerospace and high-performance industrial applications — chosen specifically because it doesn't crack, fade or lose flexibility over time the way standard rubber does.
The sailcloth texture gives it the structured, woven look associated with nautical sport watches, without the moisture retention or stiffness of actual fabric. It sits flat against the wrist, moves with it, and looks intentional on the 300M's case rather than like an afterthought.
The clasp is brushed stainless steel deployant. It matches the finishing of the Seamaster bracelet hardware, distributes wrist pressure evenly across the full strap length, and significantly reduces wear at the fold point versus a traditional tang buckle. For collectors who switch straps regularly, that matters — the strap lasts longer, and the experience of putting it on and taking it off is notably better.
Quick-release spring bars are fitted as standard. No tools, no risk to your lugs.
Sized at 20mm to fit current-generation Seamaster Diver 300M references (42mm case)
