ISOfrane emerged in the early era of modern dive watches, earning a following among divers who needed a rubber strap that could handle long hours in the water. One of its defining traits was an innovative vented structure, using wide slots to reduce trapped moisture during active use.
That kind of practical thinking shaped ISOfrane’s reputation early on, and the overall design has stayed remarkably close to those first straps rather than evolving into something new. It remains a dive-focused format built for utility instead of trends. The collection centers on the 1968 model, which follows the same clean, vented format the brand has been known for since its beginnings.
