FKM rubber watch strap 20mm blue Tropic type

The blue in the Tropic range

Deep and marine, this blue suits a diver as well as a regatta chronograph.

The Tropic type emerged in the 1960s to equip instrumental diving watches. Seawater-resistant, quickly adjustable and wearable over a wetsuit, it soon won over manufacturers, who sometimes fitted it as standard alongside steel.

A collector's standard, like the NATO

Back in fashion with the neo-retro wave, the Tropic remains an enthusiast's signature. It equipped coveted pieces: Lemania Regatta Yachting, Tissot Seastar or Yema Yachtingraf. Our model faithfully restores its basket pattern, notched border and embossed back.

FKM rubber, a premium elastomer

Unlike low-grade rubbers that whiten, our FKM keeps its colour and suppleness season after season. This hypoallergenic fluoroelastomer withstands seawater, sun and perspiration without degrading.
