With over 100 precisely calibrated working parts, including 21 jewel bearings, the shock-resistant and anti-magnetic Men’s Automatic Self-Winding Mechanical Exhibition Caseback Bracelet Watch from Bulova is an exquisite timepiece. Luminous hands and markers with silver accents join small silver numbers, markers, and indices on a sleek brown dial. But it’s the on-dial aperture and exhibition caseback views of automatic, mechanical movement in action that truly set this Bulova original apart. Water resistant to 99 feet, with a scratch-resistant crystal, this one-of-a-kind timepiece never requires a battery, and looks sharp with work and dress wear.
