I purchased this watch,while I was on a cruise  vacation........I wanted a good diving watch that I could go diving  and snorkleing with.........I have had experience with citizen  eco watches before. And I must say. I have never been dissapointed........
And I"m happy to tell you, That this watch perfomed flawlessly........I went diving in the Caribbean.to a depth of 35 feet down
and on various photo snorkleing trips.......and the watch performed exactly as it should........I would recommend rinseing off the watch with tap water, once it has been exposed to salt water, just to Insure the Integrity of the seals, of the watch........otherwise thats the extent of your Maintence.......The Eco portion,Insures you will always have plenty of battery power
I very much reccomend this teriffic Diver watch!!
