Product Description

The Seamaster Diver 300M is a watch built to go in the water. This diver-profile FKM rubber replacement strap is built to match that. Made from FKM fluoroelastomer, the same class of rubber used in aerospace and high-performance industrial environments, it resists heat, sweat, UV exposure and saltwater without cracking, fading or losing flexibility over time. The thick diver profile keeps the purposeful, tool-watch aesthetic of the 300M intact, sitting flush against the 42mm case exactly as a dive strap should.

Available in ten colourways including Navy, Blue, Orange, Red, Green, Dark Brown, Beige, Grey, Black and White, with a brushed silver buckle and quick-release spring bars pre-installed. No tools required to fit. Compatible with post-2018 Seamaster Diver 300M references with a 20mm lug width.

Key Features

  • Thick diver profile, designed specifically for the Seamaster Diver 300M aesthetic
  • FKM fluoroelastomer, heat, sweat and UV resistant
  • Brushed stainless steel clasp with quick-release spring bars pre-installed
  • 20mm lug width
  • Available in 10 colourways

What's Included

  • FKM rubber diver strap
  • Brushed stainless steel buckle
  • Quick-release spring bars

Fits: Omega Seamaster Diver 300M 42mm (post-2018), Seamaster 300, Tudor Black Bay and compatible 20mm lug watches.
