Made with FKM rubber with Nylon canvas stitched on top. The High grade Fluoro-Elastomer (FKM) rubber typically used in the aerospace and aviation industry for class leading durability. Excellent resistance to UV rays, extreme temperatures, mechanical stresses, chemicals, and seawater. Strap is non-toxic, non-marking, non-allergen and does not attract dust.

We calibrated a subtle thickness tapering for wear comfort as number one priority. Please note that this is a straight end strap and should fit universally on most watches with the right lug width.
