The Patek Philippe Nautilus Haute Joaillerie reference 5980/1400G-010 is a premier luxury chronograph that integrates high-end horology with extensive factory gem-setting. This 40.5mm timepiece is crafted from 18K white gold and features an elaborate setting of 893 brilliant-cut diamonds and 191 baguette-cut diamonds, totaling approximately 20.08 carats across the case, bezel, and integrated bracelet. The design maintains the collection’s iconic rounded octagonal silhouette while utilizing a screw-down crown and sapphire crystal case back to support a water resistance of 30 meters.
At the core of the watch is the self-winding caliber CH 28-520 C, a flyback chronograph movement featuring a vertical clutch and a 21K gold central rotor. The complications are centered on a sunburst charcoal gray dial with a black-gradient rim, characterized by a unique mono-counter at the 6 o’clock position that combines 60-minute and 12-hour totalizers. Additional features include a date aperture at 3 o’clock and nine baguette-cut diamond hour markers, providing a power reserve ranging between 45 and 55 hours.
General reviews of this reference emphasize its status as an exceptionally rare, off-catalog piece typically reserved for Patek Philippe’s most established clientele. Experts frequently highlight the masterful execution of the gem-setting, noting that the combination of baguette and brilliant-cut diamonds enhances the watch’s architecture without compromising its sport-luxury identity. While the watch is praised for its technical precision and visual depth, some collectors note that its significant weight and specialized aesthetic make it a “statement piece” rather than a standard daily wearer.
