My Hamilton 992 railroad watch, as made in Lancaster, PA about 80 years ago I think. Keeps pretty good time; wear it almost every day. It's getting hard finding watchsmiths who are experienced in working with these. Railroad watches sport dials which are extremely easy to read and are "lever set" so as to prevent inadvertent changing of the time.

No voltage. It's mechanical. ...
