Promaster Diver is rated 4.3 out of 5 by 3.
Rated 5 out of 5 by from Best watch I have ever owned I was issued this watch in 2005 after completing a very difficult military school. I have had this watch in every deployment I went on from 2005 till I retired from the military in 2012 and continued to deploy as a contractor with watch. It has been through some of the harshest environments on the planet. Still going strong, after 17 years I am just now Dec 2017 having to replace the watch band..If you want a watch to stand the test of time I fully recommend the BJ8050-08E. My son who is now 22 has asked for me to make sure he gets the watch when I check out, it is now in my will.

Rated 5 out of 5 by from ECOZILLA This is great professional dive watch, water resistant to 300 meters and comes with a strap extender to fit over your wet suit. But this watch isn't just for diving, it has a cult like following and people customize this to fit their personal style. Introduced in 2004 this remains a very popular watch today.

Rated 3 out of 5 by from I’ve owned Better! I’m a commercial diver and dive in various environments. First time I took this watch on a murky dive I noticed the bezel won’t spin anymore, most likely from the murky stuff? I contacted Citizen multiple times and have not received a reply back. Last watch I buy from them unfortunately as I own 5 of them.
