Watch & Clock Case Marks

Friday, March 30th, 2012

What is a Case Mark on a Watch or Clock?

When a watch or clock is repaired, horologists stamp or scratch a system of small letters and numbers inside the back of the case. This records who has worked on the timepiece and can be used to correspond to records at the repair shop. Although each business has their own record-keeping system, these records could describe what actions were taken to fix your watch or clock, the ownership of the piece at the time of repair, etc.


The American Watchmakers-Clockmakers Institute is the only repository for watch and clock case marking information in the U.S. We have issued over 5,500 case marks to date. We will provide case mark information in two instances:

1) To our members to help them identify prior repairs, and
2) To law enforcement in the case of theft or forensics investigations.


Online Watchmaking

Friday, March 30th, 2012 offers online courses for
those interested in learning the basics of watchmaking:

The course materials are entirely online, so you can take the course anywhere in the world where you have internet access. Once you enroll, you will receive a user name and a password to access the Level you signed up for. You can view the lessons at your leisure, and print them out if you like.  

These courses do not cover sufficient ground to allow you to begin diagnosing problems and repairing broken watches. The courses are intended to give you a good appreciation for basic watchmaking tools and skills, and for simple mechanical watch movements.  Please contact if you desire to learn more about watchmaking after completing the TZ Watch School courses.
