From the Alpina Seastrong Diver 300 Heritage collection, this men's watch features an ivory dial with a screw-down crown, a 60-minute internal turning bezel, and a date display at the four o'clock hour in a 42.0mm stainless steel case. Automatically generating electrical energy by the motion of your wrist, this watch stores the energy in a self-recharging battery that never needs to be changed. The black rubber strap with white stitching secures with a buckle clasp. Water-resistant to 300 meters, this watch includes a one-year limited manufacturer warranty.
