This Citizen Eco-Drive Promaster dive watch is a great value for the money. I like it so much that I bought a second one! Being all stainless steel construction means it won't corrode in saltwater and being rated as waterproof to 200 meters (660 feet) makes it suitable for most any diving conditions. It is as accurate as my Rolex Submariner, which is saying a lot! And it is very stylish, with gold-tone trim on the bezel and numbers. I almost forgot to mention the adjustable band makes it easy to place over your dive site with just a press of the latches under the clasp.
Can't go wrong with any of the Citizen Promaster series dive watches. I have several in my collection, with a couple that have been through very demanding conditions.
