Jean-FranÃ§ois Ruchonnet, working with Marc Alfieri, placed his spectacular vertical Cabestan movement in the center of the timepiece. Perfectly balanced at 12 oâ€™clock and 6 oâ€™clock, he added two solar panels mounted in metal frames held in place by cleverly designed pivots. The micromotors and rechargeable lithium-ion batteries are positionned to be discretely visible underneath the solar cells. In the middle of the movement, the twin-blade contact and its glass casing, based on the designs of 19th century scientist LÃ©on Foucault, is eminently visible.
Solar-powered watch or solar-powered house? Tough decision…I know.
