I am a retired Green Beret and have been diving the same watch since the early '90s and it still runs like a champ. Very reliable and easy to maintain.
Have two originals, one I bought in 1987 and was thrilled when I heard about it. Got it quickly but noticed the watch finish was coming off around the bezel. Bought a second and will to check that one when I open it.
Beautiful looking watch with the right contrast in metals! Great job Citizen.
Have older model for diving with computer. Enjoy reflecting on prior dives. Anniversary nice edition. Put it to work on occasion.
