Originally engineered for the rigors of aerospace and automotive engineering, FKM (Fluoroelastomer) is the gold standard for high-performance watch straps. Unlike standard silicone, which can be a magnet for lint and prone to cracking, our FKM straps are naturally dust-resistant and virtually indestructible. Whether you’re facing extreme heat or salt water, this DuPont-pioneered material maintains its rich color and supple feel without fading or weathering.
