Patek Philippe Nautilus 5740/1G-001 Perpetual Calendar

The Patek Philippe Nautilus 5740/1G‑001 is the first Grand Complication in the iconic Nautilus collection, seamlessly blending sporty elegance with technical sophistication. Housed in a 40 mm white gold case only 8.42 mm thick, it features a striking blue sunburst dial embossed with the signature horizontal wave pattern and highlighted by luminescent white-gold baton hour markers and hands. The bezel’s polished chamfers and vertically satin-brushed surfaces accentuate the porthole-inspired design. It is water-resistant to 30 m and features a screw-down crown and sapphire crystal case back, revealing the exquisite movement within.

At the heart of this masterpiece beats the ultra-thin self-winding Caliber 240 Q, a renowned 22K gold micro-rotor movement powering the perpetual calendar complication. It elegantly displays day, date, month, leap-year cycle, 24‑hour indication, and precise moon phases, all while maintaining an impressively slim 3.88 mm thickness. Composed of 275 parts and 27 jewels, this caliber operates at 21,600 vph and delivers a minimum 38‑hour power reserve. The integrated white-gold bracelet, which alternates polished and satin-finished links, closes with a patented fold-over clasp featuring four safety catches for enhanced security and comfort.
