Bulova Men's 98C61 Marine Star Watch

A great everyday watch, this sporty Bulova Marine Star stainless steel men's watch will also stand up to the rigors of recreational scuba diving, with water resistance to 200 meters (660 feet). It features a silver watch case with a satin finish that measures 37mm wide (1.46 inches), and it's topped by a black-plated unidirectional rotating bezel with silver elapsed time markings and coin-edged detailing for a sure grip when diving. The black dial face is complemented by round, silver-outlined luminous markers, large luminous hands (with red-tipped seconds hand), small minute indexes, and a day/date window at 3 o'clock. It's completed by a comfortable black rubber strap. Other features include a hardened mineral crystal and screw-down caseback and crown.

How to Use the Elapsed Time Bezel
If your watch is equipped with a rotating outer dial with one-minute graduations, this can be used in various ways to check elapsed time. For example if you're diving and have a 30-minute air supply, you can set the outer ring so that the bezel's starting point is in line with the minute hand when you first submerge. The minute hand will then indicate on the outer ring the length of time that you've been under water and when you should safely begin to resurface.
