      Very nice clock.
      Old and apparently in remarkably good, museum quality condition!

      Some of his more ornate clocks sell at auction for thousands of $.
      Here are a few links I found online:
      Hope that helps a little.
      Nice catch!
      Thanks for sharing.

      Thanks for an update. Paid $350 US for it. Could it be a reproduction?
    3. Bruce99 Bruce99, 5 years ago
      I think it would have to be a remarkably good reproduction, but it's possible. If you have access, can you add a well-lit photo/closeup of the movement?
    4. ACorbin, 5 years ago
      That's the best I could do

      If it is a reproduction (or counterfeit) , it is a relatively old one done by someone very skilled. The patina fasteners and general design all look authentic to me, but I'm no expert in French Clocks. French clocks are notoriously difficult to nail down. You might get more clues by unscrewing the strike bell. Sometimes stamps, similar to the serial number, are located on the brass plate behind the bell.

      You may wish to post your photos and information on the National Association of Watch and Clock Collectors Message Board. There are some collectors who are very knowledgeable about French Horology there. The website is You would need to register and I recommend that you post in the "Clocks General" forum. If no one can authenticate your clock there, you can always initiate a research request with the NAWCC Library. See: If need be, they will contact the Museum's Curator and Staff to help.
      At face value, in my opinion, I think that the clock is worth every penny you paid for it. It wasn't a "steal" but as a clock collector, I think you made a good purchase. Thanks for taking the time to post the additional photos. Happy Collecting! :)
