Piaget Centenario Coin Watch from 1970s

The Piaget Centenario is a 39mm coin watch crafted from an Mexican fifty-peso gold coin. The obverse features the Angel of Independence, a symbol instantly recognizable to anyone familiar with Mexican history. 

While the Rolex Centenario 3612 has become widely known among collectors, far fewer are aware that Piaget quietly produced around 100 pieces in total of the Piaget Centenario.
