How do I Date a Cartier Clock?

Search the clock for clues. Look for a serial number on the clock. According to the information on the Cartier website, Cartier products come with an individual number that identifies each item. These numbers tend to be small, so look the clock over with a magnifying glass. Also, don't forget to check any material that came with the clock, including the box, instruction booklet or even an old receipt. Some of these items may be dated.

Look for guidebooks on clocks. Studying general guides written for clock collectors can give you clues on how to date a Cartier, especially when they show pictures of specific models and give their manufacturing dates. Also, there are books written specifically about the Cartier company and their products which are helpful in dating their wares. Some of these titles are "Cartier: Wrist &Pocket Watches, Clocks: Identification &Price Guide" by Roy Ehrhardt and Joe Demesy, "The Cartier Collection: Timepieces" by Francois Chaille and Franco Cologni, and "Cartier and America" by Martin Chapman and Karen A. Levine.

Get an appraisal. Because Cartier products are luxury items, it is often worth appraising them for insurance purposes. Hiring a professional will not only give you the value of your piece but also provide other information such as the piece's age and condition. Contact an agency such as The American Society of Appraisers or the International Society of Appraisers to find an expert who specializes in fine timepieces.
