Chapter 124 Course Catalog


Chapter 124 offers the following classes and workshops as a service to members. A central mission of the Chapter is to provide quality education in professional repair techniques and historically accurate clock and watch restoration. Classes offered are useful to Chapter members wanting to maintain their personal collection, for those wanting to improve skills acquired previously or for members who wish to start a clock or watch repair business. Thanks to the contributions of dedicated volunteer instructors and low overhead costs these educational experiences are offered at a modest price. Upcoming classes are listed on the Chapter 124 web page. Click on Education and then Workshop Schedule to find the list of classes.

In the Chapter catalog classes are arranged in categories and have a course number and prefix to help students identify course content. Typically classes are offered at both the basic and advanced skill levels. The numbering system (100, 200, 300 and 400) refers to the skill level needed to benefit from the class. Classes in the 100’s and 200’s teach fundamentals, while intermediate to more advanced classes are number 300 and 400. Pre-requisites are identified in the course descriptions. Some classes address repair of working mechanisms while others focus on restoration of cases, statues and dials. Clock and watch repair classes are taught separately. The education program also offers instruction in the fundamentals of operating tools used in clock and watch repair.

Course Sequence Suggestions

Mastery of repair skills requires accumulated knowledge and experience. Students are asked to take foundation courses (CR-100 and CR-200 or WR-100) before attempting more advanced instruction. Even those with considerable experience in clock and watch repair will benefit from taking the foundation classes. Once the foundation classes are completed, students can build additional skills by taking more advanced and specialized courses. Skills to work on specific categories of clocks can be acquired through classes covering specific types of movements such as Fusee clocks. Clock Case and Dial Restoration classes are less reliant on prerequisites and may be taken whenever the student has interest. Basic classes are offered once a year while the more advanced classes typically are offered in a two-year rotation. If you have questions about upcoming classes and whether a class is appropriate for your skill level, contact the instructor or Education Director. Instructors’ phone numbers and e-mail addresses are listed on class announcements. The Education Director’s contact information is listed in the Education section on the Chapter web page.

Tools and Supplies for classes

Clock and watch repair require specialized tools and most beginning students have a limited collection of these tools. In recognition of the expense involved in acquiring specialized equipment, Chapter 124 maintains an assortment of tools for student use. These are available for use during repair classes and open bench workshops to lower the initial cost of working on clocks and watches. Eventually many students acquire their own tools as they learn to recognize the value of specialized tools in repair work. Class announcements list tool and material requirements for classes. Typically instructors forward class information and tool lists to students upon registration. Most materials used for projects are supplied by the Chapter. Occasionally a nominal materials fee is collected in addition to the registration fee.
