The Bulova Marine Star men's watch is a classic timepiece with a legacy stretching back decades. The open heartbeat automatic 21-jewel movement is showcased in the dial aperture. The stainless steel case is accented with a sunray dial with Roman numeral hour markers and a flat mineral crystal to protect it. The textured silicone strap is perfectly matched for a seamless look and the watch is water-resistant to 200 meters, living up to its name as a timepiece that can go wherever you do without missing a beat.
