Patent Pending: Rapid Calendar Correction (2356/98)
Owners of watches with perpetual calendars know how cumbersome it can be to set the display to the correct date when the movement has been left unwound for a long period of time. Usually, this requires pushing several buttons in the case - often dozens or even hundreds of times, depending on how long the watch remained unwound. This awkward procedure has been considerably simplified by the patented rapid correction feature of the Star Caliber 2000. With one single push of the rapid corrector slide, the owner can perform a correction of nearly one month. And because of the extensive synchronization concept, the running equation of time as well as the sunrise and sunset times are corrected automatically. Once the date is set, only two more adjustments are required: the day of the week and the time.

1952: The Gyromax Balance (26143, 280067) 
A balance with recesses in the rim each having a peg parallel to the axis of the balance and with sprung adjusting-weights held centered on the pegs.The development of special alloys for balance springs eventually made the compensating balance wheel obsolete. But the best mono metallic balances still had projecting screws so that watchmakers could make fine adjustments to the moment of inertia.Patek Philippe designed an entirely new type of mono metallic balance that replaced the screws with small weights fixed on the rim of the balance wheel.The weights are small sprung rings which fit onto pegs standing parallel to the axis of the balance wheel. They have to be shaped so that their center of gravity lies on their axis.Weights and pegs are sunk in recesses cut into the rim of the balance so as to reduce wind resistance.The moment of inertia can be adjusted by turning the weights, but in practice this is seldom necessary, because the Gyromax balance can be poised extremely precisely, adjusted closely, and it will keep it's rate almost indefinitely.The Gyromax balance has been used in all Patek Philippe's wristwatch movements since the final development of the idea was patented in 1952.
1902: Double chronograph (27052)
The double chronograph differs from an ordinary chronograph and from a chronograph with a fly-back hand in that it permits a series of observations of differing lengths.The starting of the two hands operates in the same way as the chronograph with a fly-back hand by pressing on a push-piece situated on the crown of the winding-mechanism or elsewhere; if pressure is exerted on another push-piece, it stops the hand of the second chronograph. A second press on the same push-piece brings the hand back to 12 o’clock and a third starts it moving again.During this time, the hand of the first chronograph can continue its movement; it will be stopped by pressing the first button, and this also stops the hand of the second chronograph; one more press on the same push-piece brings the hands of the two chronographs back to 12 o’clock.The timepiece is thus ready to function as if doing so for the first starting.
