Patek Philippe Nautilus White Gold — Black Diamond Dial with Moon Phase | Ref. 5724G-001

When Gerald Genta conceived the Nautilus porthole in 1976, he could not have anticipated that half a century later Patek Philippe would still be finding new ways to inhabit that shape. The reference 5724G-001 is one of those expansions — a 40 mm white gold Nautilus whose case is set throughout with diamonds, converting an already covetable sports watch into something approaching jewellery-grade artistry. The sapphire crystal exhibition case back reveals the self-winding calibre 240 PS IRM C LU, one of Patek's most accomplished movements, running at the heart of a watch water-resistant to 120 metres.

The black dial — offset dramatically against the diamond-set white gold case — carries gold-applied hour markers with luminescent coating, ensuring legibility wherever the wearer happens to find herself. Calibre 240 PS IRM C LU offers a remarkable package of complications: instantaneous date display, a genuine moon phase accurate to within one day per century, a power reserve indicator, and a seconds subdial. Approximately 48 hours of reserve are stored within the slim rotor mechanism that is itself a hallmark of Patek engineering — occupying minimal space yet winding with dependable efficiency.

A Nautilus fold-over buckle on the leather strap provides a sporting nod to the model's origins, while the diamond surround elevates the reference into the rarefied realm of grand complication jewellery pieces. The 5724G-001 represents a philosophy that Patek has long embodied: that serious horology and serious beauty are not mutually exclusive pursuits. Those who live by that belief will find in this reference a companion that repays a lifetime of attention.
