FKM rubber watch strap 20mm khaki Tropic type

A collector's standard, like the NATO

The Tropic now ranks among vintage strap essentials, beside the NATO and perlon. It featured on sought-after timepieces: Aquastar Regate, Lemania Regatta Yachting or Yema Yachtingraf. Basket weave, notched edge and embossed back mark our version's authenticity.

The khaki in the Tropic range

Sober and rugged, khaki evokes adventure and tool watches.

Popularised on 1960s divers, the Tropic owes its success to simplicity: salt-resistant rubber, comfortable, tool-free to adjust. It equipped military watches and marine chronographs alike.

FKM rubber, a premium elastomer

This model uses FKM rubber, a next-generation elastomer for seawater. UV-stable, it does not fade, withstands heat and cold, blends suppleness and toughness. Silicone-free, it stays dust-free.
