Lot Essay

Reference 3603 houses the Beta 21 movement that was revolutionary at the time. It was used by many other brands to power their quartz watches. This watch was a huge step in a different direction for Patek Philippe and remained the largest watch they made until the 21st century. This is an early example of the reference as the 3603 was produced from 1973 to 1982.

Furthermore, this example is extremely rare as it is a white gold example on leather bracelet as confirmed by its archive. To date, there are less than fifteen examples in white gold on leather bracelet that have come to market.
