Schuluhr Unitas

Updated: Feb 9

It was a great shock when my watchmaking fellows and I were confronted with the fact that the previously distributed IWC pocket watch movement was replaced with a simple Unitas movement...

Each watchmaker apprentice received a pocket watch kit allowing him to execute miscellaneous work and to deepen the knowledge. At the end of each apprenticeship it represents an individual masterpiece. Well, the use of a Unitas caliber instead of the IWC pocket watch movement was not a challenging argument and we still regret for not being supplied with a IWC movement! My personal masterpiece was anyway being crafted aside the official Unitas torture!

Anyway, back to watchmaking! In order to work on customizing the Unitas caliber 6497 movement, I prepared couple of balance-cocks for me and my fellow apprentice to work on. The cock could be transformed, differently shaped or finished entirely based upon each’s individual vision and motivation.

During our 4-years of apprenticeship the following different work were demanded by the watchmaking school in Solothurn:

  • Manufacturing an anchor bridge in steel

  • Turning a new balance-staff

  • Shaping a Breguet hairspring

  • Replacing the standard balance-cock
