This 18k white gold Patek Philippe Nautilus MoonPhase Perpetual Calendar Ref:5740/1G-001 is rated 9.9 out of 10. It comes with tag, pin pusher, booklet, box and paper dated in December 2018.
The first Grand Complication in the Nautilus collection, the Reference 5740/1 Nautilus perpetual calendar, offers a distinctive blend of sports appeal and technical sophistication. Thanks to the famous ultra-thin self-winding caliber 240 Q movement, the case (water resistant to 60 m) is remarkably svelte, making this watch Patek Philippe’s thinnest perpetual calendar. The bracelet is equipped with a new fold-over clasp providing optimized security.
