Piaget Coin Watch Centenario 39mm from 1970s

The present example is a coin wristwatch by Piaget, powered by the in house ultra thin 9P movement launched in 1957 that measures only 2 mm thick and boasts a 36 hour power reserve, and a frequency of 19,800 vph.

The Centenario is a  special fifty Mexican pesos coin commemorating Mexico's independence. The obverse side of the coin features the Angel of Independence, a symbol of Mexican independence. The reverse side shows the Mexican Coat of Arms, featuring an eagle with a snake in its beak atop a cactus, symbolizing the Mexican people's struggle against their adversaries. The coin is crafted in 22k gold while the watch is crafted in 18k gold. The side by side pairing of the gold gives the watch a two tone effect adding to its beauty. For the numismatists of the watch collecting community, the present lot is a wonderfully preserved example of ingenious design and technical know how. Last year, in November 2024 a Rolex Centenario Coin Wristwatch did $110,000 at auction which is interesting since the Piaget and Rolex examples appear to be made by the same manufacturer, Most likely Piaget.
