ISOfrane, soft, durable and comfortable, possibly the best dive watch strap you’ll ever buy!


Watch strap - Back to Switzerland in the 60s

When the makers of the greatest dive watches needed a rubber strap in the 60s and 70s, they chose ISOfrane!

Sometimes the simplest design is the best…

When our first ISOfrane dive strap debuted in the early 60s, it has quite literally changed the shape of diving - or at least the shape of dive straps!  Before, dive watch straps were usually made from rubber.They were sticky, uncomfortable and would often blister and crack when often exposed to the sun salt and cold. These straps were even harder on the divers wearing them. Without ventilation, the skin didn’t breath. The ISOfrane strap changed all of that.


Our original ISOfrane straps were manufactured using a compound called isoprene. And just what is isoprene? Isoprene is a, liquid hydrocarbon that is obtained in the processing of petroleum and is used as a raw, chemical material. Isoprene was far more durable, and maintained its looks.

ISOfrane today..

We used our old recipe, made it non-allergic, non-toxic and added even more durability and softness to rubber WITHOUT using silicon (the dust magnet) to bring back the forgotten ISOfrane dive watch strap, which is probably the best watch strap you’ll ever buy.
