Solar-Powered table clock with perpetual calendar Ref. 503
This fine Patek Philippe solar table clock is a rare model with a perpetual calendar from 1963. The luxury watch manufacturer Patek Philippe had combined its mechanical know-how with the latest technology.
The table clock is equipped with a mechanical movement caliber 17-250Q, the movement is not wound with the crown, as usual, but powered by light. A large solar panel on top of the case supplies the energy to a storage device, which in turn transfers the energy to power the mechanical movement. An accumulator cell is also provided for backup. The fine matted, asymmetrical dial has the following displays such as the day of the week, the date and the month. The case is made of gold-plated brass and is 20 cm wide, 13 cm high and 9 cm deep. A Patek Philippe extract from the archives is included.
