Here is our "Tropic" strap, a classic that has made a comeback from the sixties, like Kelton. The Tropic strap has always been the trusty companion of divers and other water sports enthusiasts, thanks to two main qualities: flexibility and durability. Our Tropic strap, which now fits the 1955 models, is made - just like in the old days - from vulcanised natural rubber, a process that uses high temperatures and sulphur to alter the structure of the rubber, making it more durable without compromising its flexibility.With a width of 18 mm and the flash pumps that come with it, it can quickly adapt to all our 1955 Mini watches.Adjustable Tropic strap made from vulcanised natural rubber.Material: Vulcanised natural rubberClasp type: BuckleWidth: 18 mm
