Swiss Patek Philippe copy watches created the “Advanced Research” series to explore new developments, components, and materials for the company’s time pieces. The research culminated in the development of Ref. 5250, 5350, 5450, and finally, the present Ref. 5550.
The mens fake Patek Philippe Annual Calendars watch houses a modified cal. 240 QP, which features a Pulsomax escape wheel and pallet fork, Spiromax hairspring and GyromaxSi balance wheel. These components are all are rendered in silicon, meaning that they do not need to be oiled.
First showcased at Baselworld in 2011, reference 5550 is a perpetual calendar that utilizes all of the company’s previous silicon developments. It is important to note that its predecessors are all annual calendars.
The present complicated Patek Philippe copy watch is offered in like new condition, and is part of a limited edition of 300 pieces only.
