Dive…
A whole genre of watches is built to see the water… Dive watches! Personally, I don’t dive or even swim, but I do have some in my collection because I like the look and feel of them. Among them is even quite a professional diver, the Rolex Sea-Dweller. Equation of Time is a watchportal that has quite a few loyal visitors and one of their fora is the dive watch forum. Give them a visit!
