It takes a long time to develop a mechanical watch like the UR-105TA — three years of research before even starting. But how long does it take to build such a mechanism? We can’t give you an exact figure, but we do know that to make and finish each of its parts needs hours of relentless work and concentration at the workbench.
We invite you to share key moments in the creation of the UR-105 TA
Clockwork Orange.
- Fashioning and finishing: all the parts for the indications are made in our premises and decorated by hand.
- Adjusting the hours carousel and watch assembly
