Bezel on a Dive Watch

Hello, I have always been curious about the fact that dive watch bezels have distinct markings for 0 - 15 minutes; what is the significance of the first 15mins in scuba diving, a reason enough for all dive watch manufacturers to consider in their watch designs?

Will appreciate your insight.
Many thanks,

Hi John-John,

Good question. Never thought about that before but, unfortunately, I do not have an answer for your question. I did some research on the internet and couldn't find a suitable answer either. I found some guesses but none that made sense to me (i.e., to let you know you have to come up after 15 minutes ; why would that be? dives don't last 15 minutes).

There is no significance for the first 15 minutes in scuba diving - at least not in recreational diving; I can't speak for technical diving since I am not certified for that.

You have me curious now. I will try and find some more information. I'll let you know if I find anything.

Can anyone else help us out here? All thoughts would be appreciated.
