Dear friends!
It seems that in silence, Patek Philippe gave the 5711 a new engine!
Cal. 26-330 s c
caliber 26-330 brand new automatic movement based on the Patek caliber 324.
To eliminate the need for the second hand to tremble and to reduce friction, it was decided to forego the typical solution of a middle wheel with a python clutch spring - which requires adjustment - and have replaced it with an innovative wheel system. game recovery.
This in nickel-phosphorus, obtained through a LIGA process (lithography, galvanic and molding), has a cutting-edge geometry, which goes to place the tooth against the wing of the pinion, without requiring any adjustment.
The rotation of the pin of the second hand in a ruby ββalso helps to reduce friction.
Intelligent automatic charging
Even the automatic recharging system has been revised in the effectiveness of the unidirectional charge. The Patek watchmakers intervened on the oscillating mass, replacing the traditional spring clutch action with a new release wheel which, in one direction, drags the barrel, and in the other, drives the spool.
Then, an additional element of automatic load disengagement was added during manual charging by replacing components, thus improving the performance and reliability of the movement.
I think it is the same basic caliber as the brand new 5212A monthly / weekly steel calendar.
