The bulova marine star watch is a classic timepiece with a legacy stretching back decades — living up to its name as a watch that can go wherever you do without missing a beat. The open heartbeat automatic 21-jewel movement is showcased in the dial aperture and the exhibition case back. With black accents, the 45mm gold-tone stainless steel case features a black dial and a flat mineral crystal. The black textured silicone strap has a contrasting red underside and the watch is water-resistant to 200 meters.
