When replacement is not straightforward
Can’t find your movement?
If the original Hermle, Kieninger or Urgos movement is obsolete, it may not need to be replaced. Eligible mechanical movements can be professionally rebuilt through our ButterBearing® service, with patented ball bearings, new bushings as needed, a three-year warranty and an approximately two-week turnaround.

Regula Clock Movements
A correct match starts with the number.
The name on the dial is only part of the story.
Which number should I use?
Read the full identification stamped on the movement’s back plate, including every suffix. Record the maker, pendulum-length marking and other stamped details. The case or dial brand alone may not identify the mechanism.
Is a similar-looking movement enough?
No. Confirm the hand shaft, mounting, pendulum requirements, drive and chime arrangement. Use the Movement Finder and ask about any uncertain match before ordering.
