From the alpina startimer collection, this men's watch features a black dial with a screw-down crown, and a date display at the three o'clock hour in a 44. 0mm 18k rose gold plated 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 suede leather strap with white stitching secures with a buckle clasp. Water-resistant to 100 meters, this watch includes a one-year limited manufacturer warranty.
