- This provides a drive device more rigid and easier to assemble.
- the plate can be reported on the display face of the dial, which allows to change the dial without changing the display device.
- the plate can also be made in one piece with the dial, which allows to minimize the number of parts in the display device and to implement micromachining techniques using lithographic processes, by producing the dial and the platinum in monocrystalline material.
