Entrepreneur Adam Mosseri spotted wearing a Patek Philippe

At an event defined by maximalist fashion statements, Adam Mosseri let his wrist do the understated talking. The Head of Instagram arrived at the Met Gala wearing a stainless steel Patek Philippe Nautilus reference 5711/1A-010 — a watch that, paradoxically, generates more conversation by trying not to. The sighting was flagged by sharp-eyed spotter @hamzamurad__, and it is exactly the kind of detail that rewards close observation at high-profile events.

The Patek Philippe Nautilus 5711/1A was introduced in 2006 as a direct evolution of Gerald Genta's original 1976 Nautilus design. The 5711 generation brought the caliber 315 SC automatic movement — a 28,800 vph, 45-hour power reserve, 3.3mm-thin workhorse — housed in a 40mm stainless steel case with the signature porthole-shaped bezel and horizontally embossed blue dial. Water resistant to 120 metres, it wears surprisingly well across both formal and casual contexts. The integrated bracelet with its distinctive tapering links remains one of the finest executions in Swiss watchmaking.

The 5711/1A-010 holds a unique position in collector culture. Patek Philippe announced its discontinuation in January 2021, citing a desire to prevent the reference from becoming a purely speculative object. The announcement had the opposite short-term effect: secondary market prices spiked dramatically. A watch that listed at roughly $32,400 USD now routinely changes hands above $120,000 on the grey market, representing a near-fourfold premium that few investment assets can match across the same timeframe.

Mosseri's professional world — algorithmic reach, cultural influence, the architecture of how images travel — makes him a fitting wearer of a watch that operates almost entirely on reputation and restraint. There is no complication to explain, no grand complication to justify the price. The 5711/1A-010 succeeds on proportions, finishing, and scarcity alone.

For collectors still hunting one, authorized dealer allocations effectively ceased at discontinuation, making private sales and reputable auction houses the only realistic routes. Grey market values for the Patek Philippe Nautilus 5711/1A-010 currently sit around $124,000 USD, with pristine full-set examples commanding premiums above that. It remains the benchmark stainless steel sports watch of its generation.
