Bulova Men's 98H39 Marine Star Chronograph Watch

A great choice for complementing professional couture, the Bulova Marine Star gold-tone stainless steel men's watch is also suitable for recreational scuba diving, thanks to its 200-meter (660-foot) water resistant rating. It features a brightly polished golden watch case that's topped by a black-plated unidirectional rotating bezel with elapsed time markings in gold and coin-edged detailing for a sure grip when under water. The busy black dial includes three golden chronograph subdials (chrono hour, minutes, and seconds) as well as gold-outlined skeleton hands (with luminous tips), large luminous hour markers, small minute indexes, a date window at 3 o'clock, and a tachymeter around the outside edge of the dial (which can be used to measure time over distance). It's completed by a smoothly supple black leather strap with white contrast stitching.

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.
