According to some sources, this time there is only one piece because it is a prototype. The more interesting because this clock was made in Switzerland in the era of World War II in 1943. The design used is quite unorthodox at the time, because of the large size and complexity of the design not be interesting at the time. Maybe you could say this is the forerunner of modern design clocks.

But if judging from the engine is used, the clock is quite simple when compared with other Patek Philippe. Another with a price that is expected to continue to increase seiiring time
