Our Tourbillon movement is the second in-house movement we did following our Caliber 801, the Caliber 20 came later. We wanted to make a Tourbillon movement that had a large cage that would be easy to see from the front, back, and side. To achieve this we had to make our own cage which is not an easy thing to accomplish, but it does set us apart from many as very few watchmakers make their own Tourbillon cage and movement.
