I have a yacht master I've only worn three times. Once when I bought it and two special occasions. I don't even think it tells time anymore.

My daily is a 7 year old Casio G-shock with atomic time keeping and Solar recharged battery. It receieves a radio signal 6 times a day for time calibration. Extremely accurate. I used it when diving in cozumel with no problems.

However I hear great things about Suunto watches. Supposed to be a great diving watch and an amazing watch for airborne military.
