Citizen Promaster Sea Automatic Black Dial Men's Watch NY0040-09E

This is a dive watch with fully mechanical automatic movement, like a Rolex Perpetual. That's what I wanted but that means it depends on the resonance of a balance wheel and hair spring for its time reference. There is no way this watch can match the accuracy of even a $30 quarts watch. Still, I was surprised that it gained 15 seconds per day which is about 8 minutes per month. I cannot depend on a watch that will gain that much time. The band and watch face are a pleasant color of blue. I have done free-diving and scuba diving with the watch and the blue really pops under water where reds are filtered out. It is still working fine and has no tendency to come loose even when freestyle swimming in the ocean. The case, crown and back are solid stainless steel as they should be. The screw down crown is easy to manipulate. The time set function has "hacking" which means the second hand stops when you set the time. I love my watch. I might try to adjust the rate, so the accuracy is acceptable.
