The purpose of rotating watch bezels, which are often associated with scuba diving, is to keep track of elapsed time, or to make other measurements, such as average speed or distance traveled.
Analog diving watches will often feature a rotating bezel, that allows for an easier reading of elapsed time of under one hour from a specific point. Upon entering the water, the diver aligns the zero on the bezel with the minute (or sometimes second) hand, allowing the elapsed time to be read from the bezel.
why do Marines wear their watch backwards? one of the reasons soldiers, particularly spec ops wear their watches backward as you put it is because the crystal face of the watch can reflect sunlight just as the lens on a sniper’s scope can do the same , so they wear their watches inverted.

Why are dive watches red and blue?
The reason we say that such coloration is mainly decorative, especially the color red, is because many colors fade as you dive under the water and light wave frequencies stop at various levels of depth. Thus, unless you have a light underwater, pretty much all the colors on your watch look blue-green.
