As a Diver we use wrist mounted computers extensively but as an Instructor I do have to get students to undertake timed skills and therefore still need a diving watch, which I can wear normally. My main computer is extremely advanced and the size of a small cellphone. I need something I can see easily in the early morning without having to press a backlight and that I can see easily underwater and that is tough enough to take it. The best diving watches are extremely expensive and expensive to have serviced so I needed a tough watch which is water resistant for diving and affordable. The Trident Pro so far has exceeded my expectations with a big clear dial and bezel, good luminosity and it's still an elegant watch. I'm delighted with it and the service that I have had from Christopher Ward. I look forward to using it for many years to come.
