The Patek Philippe Advanced Research reference 5550P-001 was presented for the first time at Baselworld in 2011.

This edition unveiled the new Oscillomax set for which the Manufacture has filed a total of 17 patents and patent applications.

Based on the legendary 240 caliber which celebrated its 40th anniversary in 2017,

this perpetual calendar is made up of 3 innovations: the Pulsomax escapement, the GyromaxSi balance wheel, the Spiromax balance-spring

These 3 components are based on Silinvar technology, a material derived from silicon, making them much lighter.

This innovation, complemented by the optimisation of the anchor and anchor wheel and by the improvement and better distribution of the aerodynamics of the balance;GyromaxSi make it possible to increase the precision and reliability of this timepiece.

Thus the Oscillomax visible through the magnifying glass on the sapphire crystal case back increases the power reserve from 48 to 70 hours.

If the watch is wound daily, the perpetual calendar will function without readjustment until February 28th of the year 2100, the secular year; where the Gregorian calendar exceptionally suppresses February 29th.

Although it takes up the features of the Calatrava, subtle details bear witness to its modernity: the change of diamond position reserved for the platinum models at 12 o'clock, a silvery back with vertical satin decoration, the choice of "railway" timer, "shell" hour-markers, hands and a modern typography give this piece a unique and recognisable design.
