The new Uhrforum watch movement identifier

More than ten years ago, the German watch forum began collecting movements that were not listed in other online movement identifiers. From the individual contributions, I have compiled all movements sorted by size on a website and as a PDF document at longer intervals.

The Uhrforum movement identifier now has a new look:

Maintaining the data in the old format was time-consuming, the search options were very limited and the data in the articles could not be changed retrospectively in the event of errors.
Due to these limitations, the new online archive was created, which offers the following advantages:

  • Always up to date
  • Extensive search options
  • Data can be easily customized or added
  • Entries can be linked to others if required
  • Information in English reaches a wider audience. The German originals in are always available as an external link

Would you like to take part in the new Uhrforum movement identifier?

If you are a member of the Uhrforum, you can add your contributions to movements clearly identified by you there:

Identifizierte Uhrwerke, die weder bei Ranfft, Lorenz noch im Watch-Wiki zu finden sind (

I will then incorporate them from there into the new movement identifier.

If you are not a member of the watch forum, please send me the pictures and data of your movements by e-mail to The pictures and data should fulfill the following requirements:

  • Pictures of the front and back of the movement
    Taken vertically from above, crown facing upwards in the picture.
  • In the case of automatic movements, if possible also a picture with the rotor removed
  • Information on as much of the following data as possible:
    • Manufacturer and caliber designation
    • Functions (manual winding/automatic, small seconds/sweeping seconds, date,…)
    • Type of escapement (swiss lever, pin lever, cylinder,…)
    • Number of jewels
    • Type of shock protection
    • Power reserve (hours)
    • Balance wheel (Glucydur, bimetallic screw balance, monometallic screw balance, nickel, brass,…)
    • period of manufacture
    • Identification (how did you find out the caliber designation of the movement?)
    • Remarks

Have fun identifying your movements with the new movement archive. And I am happy about every additional movement!
