I use a Wenger diver's watch, with the blue face and a date window. I've used it diving many times, down to around 80 ft. Never had a leak or other failure. Keeps excellent time. The only weakness is that after years of very hard use, you will have some scratches on the crystal. For $70-80 from Campmor, you don't get one of those nice synthetic emerald crystals that rarely scratch.
