What is the origin of this watch movements archive?

In 2011, members of the German watch forum UHRFORUM.de began collecting data on movements that were not yet available in any of the existing, larger archives. In addition, I (member Badener in the Uhrforum) created an HTML and a PDF version of the archive at longer intervals, in which the movements were sorted by size and contained links to the corresponding posts in the Uhrforum. In this form, the archive could serve as a movement identifer.

Maintaining this data was time-consuming, the search options were limited and the data in the posts could not be changed retrospectively in the event of errors.
Due to these restrictions, this online archive was created, which offers the following advantages:

  • Always up-to-date
  • Various search criteria -> see How to Search
  • Data can be easily adapted or added
  • Entries can be linked to any other as required
  • Information in English reaches a wider audience. The German originals in UHRFORUM.de are always available as an external link

Is there any commercial interest behind this archive?

No, it is compiled by movement aficionados for people with an interest in movements. No ads, no bullshit, just watch movements!

Can I buy watch movements shown in this archive?

Sorry, that’s not possible.

Can I send you watch movements for repair?

Sorry, that’s not possible. Please contact a watchmaker, or seek help in a watch forum of your choice, e. g. UHRFORUM.de or WatchUSeek.com.

Can I contact you?

If you are a member of UHRFORUM.de you can send a private message to member Badener. Else please send an email to

How is the size of a watch movement measured?

For round movements, the diameter is indicated, for form movements, the length of both sides. The value of the side on which the winding stem is located is given first:

In both cases, the value is given in French Lignes (or Lines): 1 ligne (”’) = 2.2558 mm.
The values are normally given in quarters or halves of lines.

Examples: 11 1/2”’ (round movement), 6 3/4 x 11”’ (form movement)

How do I convert French Lignes into mm?
