I have a Rolex clock that is commonly known as the Hoof or Sabot clock. It's from ca. 1960. It has a 15-jewel nickel-finished lever movement powered by a 3LR12 (max. 4.5v) alkaline battery. I'm looking for someone to repair this clock, ideally someone who's familiar with it. It was working until recently but is not now. (I've replaced the battery.) Thanks very much.
