Men's Automatic Watches

No battery to replace: men's automatic watches, also called self-winding, are powered by the motion of the wrist, as a rotor tensions the mainspring. Most models here show it off through a transparent caseback, and many add a power reserve indicator that tells you how much energy is left. Stainless steel cases, mostly silver-tone, sit on leather straps, black or brown.

Eichmüller and Riedenschild provide the core, with Carucci and Raptor too. Left unworn for a day or two, the watch may stop, and a few turns of the crown restart it. Keep it away from strong magnets, which can upset accuracy. Openwork pieces are in the skeleton watches.
