Revolution looks at some of the Perpetual Calendars that have been influential in this leap year.?We start with the Patek 97975. This is the first perpetual calendar wristwatch in the world that was actually created as something else.
Patek's first perpetual calendar wristwatch dates back as far as 1925.?In reality, however, the movement of this watch dates back to 1898 when Patek made it possible for the movement to be kept in a pendant watch.?It's fascinating to see their thoughts at the time.?This extraordinary complication that can keep time, date and month, year, and even the moon phase, would be appealing to a specific female client.
This extraordinary instantaneous perpetual clock movement, No.?97975 was re-cased with a gorgeous yellow-gold wristwatch, complete with hunter back and large fluted crown.?Case No. 34.4mm in diameter?The stunning hand-engraved lugs (case No. 22 033) were also included in the 34.4mm-diameter case. This tradition is still carried on by Patek today.
Patek's 12-ligne No.?The September 1898 Patek records of the 12-ligne No. 97975 movement state that: "Perpetual Calendar and Moon below XII," date at the center, days, weeks at IX, months at III." However, this is not what the watch looks like today.?This shows that the grand feu enamel dial, which was originally intended to be worn crown-up at 12 o’clock, was changed 90 degrees to its original orientation by the movement.
Small seconds now appear at 9 with the moon phase and crown at 3.
TheNo.?The 97975 movement was made of a Victorin Piguet Ebauche. It featured a straight-line lever escapement and compensating balance, as well as a Breguet Overcoil hairspring.?The most impressive feature was the unique complexity of the perpetual calendar indications that were instantaneous.
The dial's perimeter was marked with a large, centrally mounted red scale.?The month subdial is at six and the day-of-the week subdial is at twelve o'clock.?This design was never repeated by Patek.?This watch was sold to Thomas Emery, an American collector. It is part of the Rolex Replica Watches
Museum's grand collection.
Amazing to think that the 97975 was created in 1925.?Patek's first perpetual calendar chronograph serially manufactured would be the legendary 1518. It would take well over 15 years before they would make it.
