Notes

Ref. 1373 was created to celebrate the 700th anniversary of the foundation of Switzerland. One of the traditional craftsmanship, Geneva enamel was used to draw many important scenes and events in Switzerland. The dial shows the flag of the original Kanton (the bull's head is Kanton Uri, the small white cross is Kanton Schwytz, and the keys represent Kanton Unterwald). The cloisonné technique was used and the motif outline uses about 20 meters of 18K white gold. The power source is from the solar cells on top of the dome. The solar power energy switches to electrical power and drives the movement. Patek Philippe took 8 months to complete this table clock.
