Watch School Curriculum

Courses are offered in Levels 1, 2, 3 and 4, and no experience is expected for enrollment in Level 1. Each level builds progressively on the skills and knowledge acquired in the previous Level. Within each level, classes are structured for progressive, enjoyable learning.

During the time a course is offered, a dedicated School Forum will be available for communication between students and instructor. Only registered students will have access to the classrooms, forum, and chat.

The Level 1 course requires the purchase of a tool kit of basic, but high-quality watchmaker's tools and supplies. A movement, for class work, is also included. The Level 2, 3 and 4 courses requires the addition of certain tools, and will also provide a list of optional tools that may be purchased through the TZ Tool Shop or elsewhere, at the student's discretion. A movement is also supplied for the Level 2 course and a watch timing machine is needed for Level 3.
