About the strap
Isofrane is an iconic dive-watch strap brand, renowned among collectors for its distinctive ladder-style, ventilated rubber straps widely used on professional dive watches from the 1960s and 1970s. Original straps were associated with brands like Omega, Aquastar, and Tissot, becoming collectible after production ceased in the 1980s. Revived in 2010 by Synchron Uhren Manufaktur GmbH, the brand now crafts natural-rubber, silicone-free dive straps in Italy, offered in sizes like 20mm, 22mm, and 24mm. The modern 1968-style reissue is celebrated for its comfort, softness, durability, and faithful tool-watch aesthetic.
