With an extract from the Patek Philippe confirming the production of the present watch in 1989 and its subsequent sale on October 18, 1989 Launched in 1989 to commemorate the 150th anniversary of the Manufacture Patek Philippe, the reference 3969 revives a complication "made in France": the jumping hour. A revolutionary complication invented by French watchmaker Antoine Blondeau in 1830, this novel system is much less fragile than a hand mechanism, making it easier to tell the time. Very fashionable in the 1920s, jumping-hour watches gradually disappeared in the 1930s. But in 1989, with the launch of the reference 3969, Patek Philippe revived this complication, which was born almost at the same time as Patek Philippe. This "anniversary" edition was produced in just 500 pieces: 50 in platinum and 450 in pink gold.
