The Horological Society of New York's award-winning classes head home! HSNY offers its weekend classes in New York! Discover what makes your watch tick, with a hands-on course taught by the Horological Society of New York's staff of professional watchmakers. Students will work on a mechanical watch movement, studying the gear train, winding and setting mechanisms and escapement. This four hour course covers everything our three individual courses cover during our NYC week-night classes.
