Blending elegant style with a sporty state of mind, the Bulova Marine Star stainless steel men's watch travels easily between formal business and easy-going casual wear. The large, round polished silver stainless steel watch case measures 41mm (1.6 inches) wide and is topped by a unidirectional rotating elapsed time bezel with a brushed finish and black engraved 10-minute marks. The patterned black dial includes extra large silver hour markers and arrow-tipped hands for easy readability (thanks to their luminosity), as well as small minute indexes around the outer edge of the dial and a date window at 3 o'clock. The silver stainless steel bracelet band mixes brushed and polished finishes, and it's joined by a fold-over clasp. This precise quartz timepiece also features a scratch-resistant mineral crystal and water resistance to 100 meters (330 feet).
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.
The Bulova Story

In 1875, a young Czech immigrant named Joseph Bulova set up shop in New York City, and a legendary American watch brand was born. Bulova was trained as a jeweler, and his expertise carried over into his watchmaking career, which began around 1911 with boudoir clocks and pocket watches, and soon evolved to include what was then one of the latest and most fashionable technological innovations: the wristwatch.
Bulova introduced its first line of wristwatches in 1919. The company grew and prospered, and soon early radio and television ads were declaring, "America runs on Bulova time." In the 1950s, continuing its legacy of innovation, Bulova introduced Accutron, the first electronic watch, and the first breakthrough in timekeeping technology in over 300 years. The Accutron timing mechanism was later adapted for use by NASA computers and a Bulova timer was even placed on the moon to control transmissions of data. Bulova timepieces have kept official time aboard Air Force One and have also served as official timepieces for U.S. Olympic teams.
Today, Bulova maintains its tradition of excellence in technology and design, offering a diverse collection of beautiful precision timepieces for every occasion.
