But how will the great unwashed know you are a DIVER if your watch does not have a bezel I suspect that may be important to some people. I will admit that my only watch is a Seiko with a red and blue rotating bezel
I rarely use a watch, any longer, outside of diving; so. I couldn't give a whit about appearances; but I've dove with an analogue watch for decades now, and have always used that functional bezel, out of habit, as a time-keeping back-up, in case the electronics go tits-up -- and they have.
One that doesn't work, is tantamount to a non-functional compass . . .
