There is a new tool that can be used to develop chronographs with different designs.
In this way, you can create your limited editions and new designs.
With the help of a tool, the cases for prototypes can be punched out and further produced in a thermal process that is similar to the production of ceramic cases in an autoclave oven. A ceramic case shrinks by about 30%; my tests with the brown material used showed no relevant shrinkage.
The raw cases are then subjected to a surface treatment as can be seen at the 2 cases on the right
The next step is to attach the dials, hands and indices. The photo shows the process of setting the hands, which is best done with watchmaking tweezers.
The production shown was a team effort in which my daughters and my partner played a key role.
This design was created by my daughter.
Here is an overview of the prototypes developed.
Many thanks to IWC for the punching tool that the participants of the Collectors Meeting received!
