Writer Giorgia Mondani spotted wearing a Patek Philippe

Giorgia Mondani was recently photographed wearing the Patek Philippe Nautilus reference 5712/1A-001 in stainless steel, fitted with one of the most quietly sophisticated dials in modern watchmaking. For a writer who has dedicated her career to documenting Rolex and broader horological history through her acclaimed Mondani Editore publications, the choice of a complication-rich Nautilus speaks to a collector who demands substance behind the signature silhouette.

The Patek Philippe 5712/1A-001 was introduced in 2006 as an evolution of the original Nautilus family, retaining the 40mm integrated bracelet case designed by Gerald Genta in 1976 while adding meaningful horological depth. Its grey-blue gradient sunburst dial — a hallmark of the reference — hosts three subsidiary functions: a power reserve indicator at 10 o'clock, a date display positioned between 6 and 9 o'clock, and a running seconds subdial at 4 o'clock. The layout is asymmetric yet balanced, a genuine design achievement given the constraints. Powering the watch is the ultra-thin caliber 240 PS IRM C LU, a 22-karat gold micro-rotor automatic measuring just 3.88mm in height, with a 48-hour power reserve and Geneva Seal finishing throughout.

Among collectors, the 5712/1A-001 occupies a specific and respected tier. It is considered the thinking person's Nautilus — more technically interesting than the 5711 time-only, yet more wearable than the grand complication references. Its discontinuation, along with the broader Nautilus 5711 family exit in 2021, has only solidified its status as a modern classic with genuine scarcity.

Giorgia Mondani is not a celebrity in the conventional sense — she is arguably more credible than most. As the author of the definitive Rolex reference books and a recognized authority on vintage and modern Swiss watches, her wrist choices carry weight in collector circles. Seeing the 5712/1A-001 on her wrist is an endorsement from someone who evaluates watches for a living.

At an official retail price of approximately $33,000 USD, the Patek Philippe Nautilus 5712/1A-001 was already a significant purchase. On the current grey market, the reference trades at roughly $120,000 USD — nearly four times retail — a reflection of sustained demand, discontinued status, and the enduring prestige of the Nautilus name in stainless steel.
