    Default Oris Depth Gauge

    What I don't understand about this watch, is the claim that it's a world-first. It's not the first watch that works by allowing water to "enter the timepiece", that's for sure (see Aquadive, IWC, and many, many more**). It also uses an antiquated, primitive and functionally inferior method to measure depth. As you can see from the photos, the depth is measured via the small channel bored out of the crystal. Water enters and compresses the air as the depth increases. This basic principle was used in cheap depth gauges in the early days of SCUBA (and can be helpful in translating altitude into "depth" when diving in mountain lakes, etc). But they were fragile and also had a serious drawback - depth was very difficult to read below about 12m. As you can see from the dial, the gap between numbers reduces in line with depth, until it's almost useless. With repeated use, the channel that they have so carefully cut may also become cloudy, due to salt deposits. It's difficult to keep clean and there's a reason nobody uses them any more. It's a decent watch, and I like the styling, but I wouldn't use one as a depth gauge, that's for sure.

    **If water pushes / acts on the case, it's entering it in my view.

    Your bleeding-edge Now is always someone else’s past. Someone else’s ’70s bellbottoms. Grasp that and start to attain atemporality.
