Mr T doing some flat polishing for his school watch. Here, he does the polishing for the screws, crown and wheel. All very good work.

Interview with Charles (a student) who restore a spring detent watch having a MALTESE CROSS on the barrel.
What’s the name of this part and for what is it’
This is the Maltese Cross. It’s made to use only the central portion of the mainspring.
Can you find it in all watches?
You can find it in older hi-end pocket watches. But it’s usually broken because some incompetent watchmakers remove it, break it or just ignore it.
With what do we replace it today?
We didn’t replace it. We just don’t use it anymore. One of the many reasons we don’t have it in our day is that it’s expensive to produce and place consuming.
Do you think the Maltese Cross is aesthetical?
Yes, it looks cool. The steel has to be hardened and polished. So it’s very shiny. But it’s on the dial side, so only watchmakers see it when they service the watch!

Pioneer in solar energy, manufacturer of many special spacecraft parts, such as the PRoVisG that equipped the Mars Rover, and collaborator in the design and construction of scientifical parts of the CERN (largest particle accelerator on Earth), the CSEM (Centre Suisse d'Electronique et de Microtechnique) opened their doors for our school during one complete day. The purpose of the visit was to show us one of the most hi-tech ways to produce watch parts in silicon with an improved and innovative technology.
Thanks again to CSEM for a fantastic visit.
