  • Catalogue Essay

    Developing a solar powered clock in the mid 60s’ must have been a daring challenge! Who else than a watchmaking company with a never-ending spirit for innovation like Patek Philippe would have been able to associate their mechanical expertise with the most advanced technology?

    Based on the same photo-electrical principles that power today’s communication satellites, this avant-garde table clock is powered by light. Even the movement only requires minimal exposure, as only 4 hours of light, natural or artificial, are required to keep the clock running for a day. The movement is further equipped with a backup battery system that allows it to work in complete darkness for at least a year. This clever feature appears to be very useful as the clock is a perpetual calendar that does not require any date adjustment.

    The excellent condition of the present example further enhances the timeless feel of its design. The modern, minimalist and asymmetrical dial displays three large apertures for the calendar that echoes the design of the airport’s arrival and departure board. This perpetual calendar clock that successfully displays great technical innovation and futuristic timeless design would be the perfect missing element in a vintage interior as well as a great addition to a contemporary interior.
