This advanced course draws together the skills developed in previous training on the watchmaker’s lathe. It focuses on further refining micro-mechanical techniques through close-tolerance lathe work, precision filing, fine thread cutting, and polishing—all essential skills for high-level horological craftsmanship.
Like the Balance Staff, the Winding Stem is one of the most common and vital components made and fitted to older watches. By the end of the course, you will be able to produce and fit a precision-made winding stem, applying professional methods to achieve exacting standards.
This course offers valuable hands-on experience for students preparing for Exam Unit D19 – The Watch Portfolio, with practice in making significant components to assessment requirements.
