3) Waffle Shape

 

If you turn to the back, you can see there are diamond or waffle like shape squares corresponding for each hole. This is not only for design purpose, but it is also very functional. Early rubber straps do not provide breathability, which is why they weren’t exactly comfortable.

With the waffle-like design, it allows less rubber or silicone touching the skin, allowing more water to pass through the strap. This will always ensure that there is enough breathability between the rubber strap and the wrists.

 

4) Two keepers

Traditional Tropic straps have two keepers while modern Tropic’s have one or two in some cases. This is for practicality purpose as most tropic straps are longer than usual to be able to wear over a wet diving suit.
