Patek Philippe unveils the Calatrava skeleton watch in an elegant rose-gold version, showcasing the ultra-thin self-winding Caliber 240 SQU movement. Celebrating 40 years of this iconic caliber, the movement is entirely skeletonized and meticulously hand-engraved, requiring about 130 hours. The winding rotor features the engraved Patek Philippe Seal logo for the first time, highlighting the brand’s commitment to rare craftsmanship. The 39mm rose gold case, with a height of just 6.7mm, is complemented by a rose gold bracelet and fold-over clasp. The sapphire crystal case back reveals the intricate, hand-engraved details of the movement, blending timeless elegance with exceptional artistry.
