The new Replica Patek Philippe Calatrava “Squelette” Ref. 5180/1R-001 comes in around rose-gold Calatrava case which is reduced to a narrow frame to places emphasis on the movement. With its large-format sapphire crystal glass and caseback, it assures total transparency yet offers optimized protection and water resistance to 3 bar (30 meters).
The aesthetic appeal and transparency with which the Replica caliber 240 SQU keeps track of time make it a miniature opus of kinetic art. Its plate and bridges are pierced to the maximum extent possible to create a seductive view without compromising the reliability and functional integrity of the movement. The work involved calls for the skill of the watchmaker who knows exactly where the limits of skeletonization lie. It takes more than a week to create the filigreed transparency of the movement.
The plate is open-worked even above the barrel, exposing the coiled mainspring beneath the pierced contour of the Calatrava cross, which has been a registered Replica Patek Philippe trademark for over one hundred years.
The next steps take place on the workbench of the engraver who further refines the watch with his artisanal skills. He invests more than 130 hours to decorate the remaining structures with vivid arabesques and volutes. The “Replica Patek Philippe Genève” brand signature is engraved on the remaining parts of the barrel frame around the Calatrava cross, which itself is also decorated.
Additionally, the “PP” logo of the Replica Patek Philippe Seal is making its first appearance of the 22K gold mini rotor.
In the end, the entire skeletonized movement chassis is plated with rose gold and then polished to match the case and bracelet. The self-winding caliber 240 SQU is framed by a movement holder ring in 18K rose gold 5N. The ring itself is also skeletonized down to 12 spokes that serve as hour markers.
With a tolerance of -3 to +2 seconds per day, the rate accuracy of the movement complies with the strict directives of the Replica Patek Philippe Seal. This is due not least to the Spiromax® balance spring made of high-tech Silinvar®. Its purple iridescent shimmer is readily visible in the totally skeletonized movement.
