Actor Mark Wahlberg spotted wearing a Patek Philippe

Mark Wahlberg is no casual watch buyer, and his choice of the Patek Philippe Split-Seconds Chronograph Reference 5370P underlines a level of connoisseurship that separates genuine collectors from trophy hunters. The sighting of the platinum-cased rattrapante on his wrist is notable precisely because the 5370P is not the kind of watch you simply walk into a boutique and purchase — authorised dealer allocations are minimal, and waiting lists at major retailers routinely stretch years.

Introduced in 2015, the Ref. 5370P represents Patek Philippe's first fully in-house split-seconds chronograph movement, the calibre CH 29-535 PS. Prior generations of Patek rattrapante watches relied on ebauches sourced externally. The new movement was a statement of horological intent. It runs at 28,800 vph, offers a column wheel for chronograph control and a lateral clutch for the split function, and delivers a 65-hour power reserve. The platinum case measures 41mm, paired with a deep blue sector dial that references classical pocket-watch aesthetics — a deliberate nod to Patek's own archival design vocabulary.

Among collectors, the 5370P occupies a specific and respected position. It is not a perpetual calendar, not a minute repeater, yet it demands equal — if not greater — respect for the mechanical complexity of a properly executed split-seconds mechanism. The rattrapante function allows a second elapsed-time measurement without stopping the primary chronograph hand, a complication with roots in 19th-century sports timing. Fewer watchmakers produce them credibly today than at any point in the past century.

Wahlberg has been photographed with a range of serious references over the years, but the 5370P raises the bar. It signals familiarity with Patek's movement architecture rather than a preference purely driven by name recognition or resale value. The platinum case and sector dial combination also suggests the piece was acquired through deliberate selection rather than a grey-market impulse buy.

On the secondary market, the Patek Philippe 5370P commands a significant premium over its already substantial retail price. UK list pricing sits around £190,980, while grey-market examples regularly trade between $380,000 and $450,000 depending on condition and provenance. Demand consistently outpaces supply, and that dynamic shows no sign of reversing.
