The watch case employs a titanium base offering superior corrosion resistance, light weight and high strength, while the surface is specially treated for high hardness and enhanced scratch resistance. The rotating bezel, which is importantfor checking diving time, employs a reverse rotation prevention mechanism that prevents the rotating bezel from being rotated inadvertently in the wrong direction. The solar power generation function transforms solar energy into electrical energy to run the watch. Since solar energy is used as the power source of this watch, it has no need of regular replacement of the battery unlike the general diver's watches using the mercury cell, etc.
The screw down locking crown is securely locked in position through the use of ascrew-locking mechanism, the use of three O-rings results in enhanced air tightness and water resistance. Furthermore, the screw down locking crown is located at the 9:00 position to prevent it from obstructing movement of the wrist or wetsuit.

Comments about Citizen Citizen BJ8050-08E Men's Eco-Drive Professional Diver Watch Strap, Black Dial:
This is a diver's watch for divers. It is not as practical as a daily wear watch due to its size and weight; however, underwater it is comforable, easy to read and extremely durable. I would recommend this to anyone who does alot of diving in demanding conditions who needs a reliable timepiece.

Pretty Great Timepiece but the titanium is lighter.
It's a very good watch but Citizen's service Department Needs much to be desired mostly paper pushers not watch tech's.
