Nice article, and I am a watch kind of guy. I feel naked without a watch. Not into dress watches, as I was always hard on watches because of the jobs I have had. Time keeping was critical for my time as a commercial diver, but it was while on the surface while running a diver in the water, or keeping time for chamber decompression purposes. No commercial diver wore a watch while working underwater, unless he just chose to do so. The majority of dives in the commercial diving world are no vis dives, meaning you have zero visibility. You wouldn't be able to read the time on a watch if you wore one anyway. All working times and decompression stops were run from the surface, by the person running the dive and communicating to the diver via underwater comms. The entire dive crew was required to wear watches, all synced to the job dive clock used for running dives.
