The FKM Rubber Strap for Omega Seamaster 300 Diver White is developed specifically for the Omega Seamaster Professional 300 Diver 42mm from 2018 and onwards. The curved ends follow the shape of the case closely, giving the watch a clean and integrated look that sits naturally on the wrist from the first wear. Made from high quality vulcanized FKM rubber, the strap is highly durable, fully waterproof, and well suited for both diving and everyday use. It remains flexible and comfortable even during long wear, while handling saltwater, heat, and daily use with ease. Installation is simple and can be done at home. You can choose between our smooth FKM rubber strap or the Vertech version with its subtle textured pattern. Both options are made from the same robust material and are designed to work equally well with a sporty or more refined look.

Fits perfectly, I've fallen in love with my watch all over again!
Hey buddy,
Love to hear that. Falling in love with the watch all over again is exactly what we aim for. Thanks a lot for the review.

An excellent strap to pair with the Seamaster in summer. Has completely changed how the watch wears, runs a touch short, but okay for my 19.5 cm wrist
Hey buddy,
That means a lot. Completely changing how the watch wears is exactly the kind of feedback we love hearing. Really glad the white FKM is doing its thing on the Seamaster.
