Tropic rubber watch band with perforated surface. The material is 100 % waterproof which makes this watch band a practical choice for the dive watch or any other timepiece for that matter!
The TPU material is a little stiffer than silicon straps, but it has a more shiny finish and is treated with dust repellant.
The straps are made from a genuine 1960's mold, with a modern and better type of rubber that doesn't attract dust. But it still has all the vintage features such as the waffle patterned underside. Please note that this type is strap is not a fitted strap, so it is not supposed to sit tight against the watch case.
