The present reference 902 is a rare, solar-powered desk clock with gilt brass case in extremely good condition, sold by and signed Tiffany & Co.

In the 1960s, Patek Philippe developed an electronics division that focused on advancing nuclear, electronic and photoelectric timings. Soon, state-of-the-art solar clocks were developed that maintained the timeless design aesthetic for which the brand was famous.

While the movement of these clocks is powered by the energy generated in their solar cells, all Patek Philippe solar table clocks from this era use a pocket watch movement for the drive. These timepieces combine the cutting-edge technology of the 1960s with the time-honoured technology of the 19th century pocket watch.
