I agree, I having had several failures over the years — both in computer hardware and software. To pick on a point in the article. I time medications, barbecues, lectures, etc. I strongly prefer bidirectional and even modify some to achieve that. I also prefer 12 hour scales for their cleaner look. I use a computer. I leave my Seiko dive watch that i love at the hotel.
Any insight on what type of spring a Doxa dive watch uses? It seems to be unidirectional but recently mine started moving both directions. The ahestetics came above functionality and the very thin hands are hard to see, depending on the conditions of the sea one is scuba diving.

Let us seek the answers to these two questions which in a way are part of each other.
A rotating Bezel is part of a dive watch — in fact, it is the most vital component of it, which distinguishes itself from regular watches. A bezel is an outer disc that is graduated into 60 divisions corresponding to 60 minutes. The 60 divisions on the bezel mark an hour which corresponds to the time that oxygen in a standard scuba oxygen tank usually lasts.
The graduations on the bezel can show from 0 to 60 or from 60 to 0. The function is the same — to provide the diver with a marker to show how many minutes have elapsed during a particular dive so that the remaining time left from an hour can be estimated so that the diver has sufficient oxygen to ascend back to the surface. This is so because after a particular time has elapsed, the body tissue begins to absorb compressed nitrogen.
This is why the first 15 to 20 minutes on a bezel are often highlighted. This is the basic use of a standard diving bezel but there are actually several types of watch bezels , including bezels that serve as tachymeters, compass, for tracking world time and much more. The rotating bezel first made its appearance in dive watches in the s — borne out of necessity and the recommendation of divers who needed a means of tracking time at the bottom with their waterproof watches. It was Blancpain also that introduced the unidirectional bezel , a provision that addressed the problem of the bezel being accidentally knocked during a dive.
