I bought this watch a year ago for spearfishing, diving, work, etc. I’m a U.S. Army combat diver and work in Key West FL teaching new combat divers. I’m in the water 2-3 days a week, most of that spent at depths ranging from 10-130 ft. I previously used a casio g-shock as a backup to my dive computer but the timer button would hit my depth gauge and stop the time, extremely frustrating and ineffective for a backup to clock TTD. The only time the g-shock was decent for the task was if it was attached to a navigation board for closed-circuit diving. Enter the citizen promaster diver: I researched various options and ended up narrowing the choice down to this watch or a seiko skx777. I chose the citizen because of the eco drive and quartz mvmt being easier to use/less attention required than an automatic mvmt. I set my promaster time by the time.gov atomic clock and after one year the time has only shifted 2 seconds. Im very happy with the amount of illum as well. Too much illum can ruin night vision of your eyes and can actually be seen on a calm clear water night from the surface as divers approach their target. I like how i can charge up the citizen w a flashlight if need be, but found that illum from normal sun exposure during the day is adequate for night diving. Overall, for all practical purposes, this watch is perfect for all the tasks i require of it. I’ve considered buying a second one just to keep NIB so that i can give it to my son when he grows up in fifteen years because I’m confident mine will still be running and I’m afraid such a fine product will cost big money eventually.
Bought this beauty after 20 years of service with my first Citizen Eco Drive. Just love the simplicity and durability of these watches. This new dive watch should last me the rest of my days. Citizen watch wearer for life!
New watch is running slow. A quartz watch that is running slow even after charging as per the instructions. It seems that owning this watch is a waste of time, how ironic.
Nice, simple, dive watch…I like the eco drive function but the band is cheap, hard, rubber…I expected more for a $400 dollar watch. Will replace the band ASAP…
