The Patek Philippe Calatrava Rare Handcrafts Lacework in Blue, reference 5077/100G-080, is an exclusive edition limited to just six pieces, crafted in white gold and unveiled during the 2026 Watch Art Grand Exhibition held in Milan. This watch exhibits a stunning design inspired by Burano lace, incorporating intricate champlevé and paillonné enamel techniques on the dial, paired with hand-engraved designs on the sapphire crystal. The enchanting floral pattern showcases delicately hammered petals, which are then adorned with a translucent enamel finish achieved through champlevé. The pale blue hues of the petals are enhanced by silver leaf layered beneath the enamel, following the paillonné method. A vibrant selection of five shades of enamel—both transparent and opaque—enriches the overall color scheme, which is further refined with several coatings of clear enamel known as flux. Each dial demands meticulous craftsmanship, involving between eight and fifteen firings at a temperature of 760°C. The sapphire crystal also features a unique hand-engraved embroidery that draws inspiration from Burano lace artistry. Time is indicated by elegant white gold Dauphine hands for hours and minutes. The 38 mm white gold case, with a thickness of 8.3 mm, offers water resistance up to 30 meters. Its bezel and lugs are ornamented with a total of 112 diamonds, amounting to approximately 0.87 carats. Observing the ultra-thin self-winding caliber 240 through the sapphire crystal case back reveals its 22-karat gold off-center minirotor. The movement, only 2.53 mm thick, operates at a frequency of 3 Hz and ensures a power reserve lasting a minimum of 48 hours. Notably, it features a Gyromax balance and a Spiromax balance spring, proudly bearing the esteemed Patek Philippe Seal. Completing the elegant design, a hand-stitched navy blue calfskin strap with a satin finish aligns with the dial's color scheme, secured with a white gold prong buckle adorned with 29 diamonds, totaling approximately 0.24 carats.
