ISOFRANE is proud to offer a new old stock of the original Swiss Made Tropic strap in 20mm. The stock of 90 pieces has been stored in our warehouse for 35 years in an airtight compartment and wrapped in a special paper, so the straps are still very supple and have no signs of wear.

We guarantee those to be 100% authentic Tropic straps from the Seventies. The Vintage TROPIC and ISOfrane straps are the most sought after straps among dive watch collectors. With this limited stock, we are bringing you a once in a life time opportunity to turn back time and give your vintage diver the best treat ever.
