Actor Robert Downey Jr spotted wearing a Patek Philippe

Robert Downey Jr sat down with GQ for a dedicated watch collection video — the kind of format that separates genuine enthusiasts from red-carpet borrowers — and among the pieces he presented was a Patek Philippe Nautilus reference 5712/1A in stainless steel. It is one of the more technically substantive choices a collector can make within the Nautilus family.

The Patek Philippe Nautilus 5712/1A was introduced in 2006 as an evolution of the 5711 platform, adding meaningful complications to Gerald Genta's 1976 integrated-bracelet design. The reference houses the calibre 240 PS IRM C LU, a micro-rotor automatic movement measuring just 3.88mm in height and decorated to Patek's Seal standard. Beyond the time and date, the 5712 layers in a moon phase display accurate to one day's deviation per 122 years, plus an instantaneous-jumping power reserve indicator — a technically demanding combination compressed into a 40mm steel case with the Nautilus's signature horizontally embossed dial and stepped bezel.

Within the Nautilus reference hierarchy, the 5712/1A occupies a considered position. The 5711 draws the loudest secondary market noise, but collectors who prioritise movement complexity over minimalism consistently rate the 5712 as the more intellectually rewarding reference. The steel variant specifically — the "1A" suffix denoting stainless steel on bracelet — has historically been the most difficult Nautilus configuration to acquire through authorised dealers, placing it in the same allocation scarcity bracket as the 5711/1A it complements.

Downey Jr's ownership fits a pattern. He has spoken publicly about watches as functional objects with personal history rather than investment vehicles, and the 5712 rewards exactly that perspective — it offers daily interaction through its complications rather than sitting as a passive status marker. For an actor with the financial latitude to own virtually anything, selecting a reference defined by its movement rather than its resale ceiling is a meaningful signal.

On the current market, the Patek Philippe Nautilus 5712/1A trades firmly above retail in the grey market, reflecting both sustained demand for steel Nautilus references and the reference's discontinuation in its original configuration. The official retail price in the UK was approximately £24,000, translating to roughly $30,000 USD at list — a figure the secondary market has long surpassed.
