AWCI 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.
What is a Case Mark?
When a watch or clock is repaired, horologists “stamp” or “scratch” small letters and numbers inside the back of the case. This system is used for your records and future reference on repairs and ownership.
Why is this Beneficial?
AWCI provides case marks and keeps these records. We will supply this case mark information to you, the owner, to help identify your repairs. We will also provide it to law enforcement in the case of theft or forensics investigations.
How Does the System Work?
AWCI has adopted this universal case mark system to be used preceding one’s own information. It is easily recognized by two numbers or letters followed by a delta symbol (triangle) then two more numbers or letters, for example:
Inscribe this on the back of each case. Then, record it in your repair records along with your customer’s name, date, and a good description of the repaired item. To acquire your case mark contact: AWCI, 701 Enterprise Dr., Harrison, OH 45030, 866-367-2924,
