At the heart of this timepiece lies the Caliber 240 SQU, an ultra-thin self-winding mechanical skeleton movement that has been entirely skeletonized, then meticulously decorated and engraved by hand. The result is an open architecture that transforms the watch into a wearable showcase of horological craft, revealing the movement's inner workings from every angle.
The 39mm rose gold case measures a remarkably slender 6.7mm in height, lending the watch an understated elegance on the wrist. A sapphire-crystal case back allows an unobstructed view of the movement from the reverse, while water resistance to 30 metres provides everyday practicality. Reference 5180-1R-001 is completed by an 18kt rose gold bracelet secured with a fold-over clasp.
Crafted entirely in 18kt rose gold — from case to bracelet — this Patek Philippe Complications piece unites the warmth of precious metal with the transparency of a fully skeletonized movement, making it a compelling choice for the discerning collector drawn to fine mechanical artistry.
