ISOfrane strap

Aquastar Deepstar strap option: ISOFRANE

We used the best 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 legendary ISOfrane dive watch band, which is possibly the best watch strap you’ll ever buy.

Hypoallergenic, with a superior fit and feel – and 100% Silicone free! The modern ISOfrane dive watch bands have been designed to replicate the original ISOfrane straps.  They bear the same attention to detail as the original with the ventilation straps and straight end lug attachments.  The ISOfrane watch band is the perfect addition to any dive watch – vintage or modern.

Aquastar Deepstar strap option: Vintage Isofrane

This strap is made to exact same specifications of the 70s ISOfrane (referred to as the Flexi ISOfrane) straps using modern rubber compounds that guarantee softness and durability. For those who prefer thinner straps, the Flexi Isofrane is thinner than the regular ISOfrane but at least as good looking.
