Tropic FKM Rubber [20mm]

A retro-inspired strap design that works great on a wide range of watches. Holes in the strap ensure great breathability, while quick-click spring bars allow for easy strap changes. Curious about FKM rubber? FKM is a class of fluorinated, carbon-based synthetic rubbers, commonly known as fluoroelastomer. FKM is characterized by high chemical stability and resistance to aging and weather. It is soft & flexible and will not attract dust and dirt like some less expensive, silicone rubber straps.
