From the alpina startimer pilot automatic 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 black titanium 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 titanium stainless steel link bracelet secures with a fold-over clasp. Water-resistant to 100 meters, this watch includes a one-year limited manufacturer warranty.
