Patek Philippe 5140G Perpetual Calendar Ultra Thin 18K White Gold Silver Dial

Introduced in 2006, the Patek Philippe 5140G‑001 continues the lineage of the revered Ref. 3940, offering a subtly enlarged 37.2 mm ultra‑thin 18K white gold case that enhances legibility and presence while preserving elegant proportions. Powered by the celebrated self‑winding Caliber 240 Q, this perpetual calendar movement features an off‑center 22K gold micro‑rotor and a mere 3.88 mm profile, delivering a refined 48‑hour power reserve and complete calendar functionality—including day, date, month, leap year, 24‑hour indicator, and moon‑phase—without compromising slimness. The silvery opaline dial is beautifully balanced, with applied white gold baton markers and dauphine hands, and the display back reveals the exquisitely finished movement, bearing the prestigious Geneva Seal. Water‑resistant to 30 m, the watch is fitted on a hand‑stitched alligator strap secured by a white gold deployant clasp, reinforcing its dress‑watch elegance. As a Grand Complication in Patek Philippe’s catalog, the 5140G‑001 is highly regarded among collectors for its technical sophistication, timeless design, and enduring relevance in the perpetual calendar genre. Like New with Patek Philippe box, travel pouch. Includes Patek Philippe service papers dated 2025 and factory sleeve.
