Pilot Christian Horner spotted wearing a Tag Heuer

The mystery is solved. The watch glimpsed on Christian Horner's wrist at the Singapore Formula 1 weekend has been identified as the TAG Heuer Monza Flyback Chronometer, reference CR5090.FN6001 — a piece handed directly to Horner by TAG Heuer CEO Frédéric Arnault at the model's world premiere earlier that day.

The new Monza CR5090.FN6001 arrives in a 42mm carbon composite case, a material choice that keeps the watch featherlight while reinforcing the motorsport DNA the Monza name has carried since 1976. The skeleton dial opens up the architecture considerably, with translucent smoky blue sub-dials providing depth and contrast, while red accents — unambiguously racing-coded — animate the chronograph seconds hand and indices. Both a tachymeter and a pulsometer scale ring the dial, a dual-scale configuration that nods to the original Monza's physician-friendly heritage without taking itself too seriously.

At the heart of the CR5090.FN6001 beats the Calibre Heuer 02, TAG Heuer's in-house column-wheel flyback chronograph movement. On this new Monza variant, the Heuer 02 carries full COSC chronometer certification — a first for the movement in this context and a credential that matters to serious collectors. The Heuer 02 offers an 80-hour power reserve, operates at 28,800 vph, and features a vertical clutch for clean chronograph starts. It is visible through the caseback and, on this skeletonised execution, partially through the dial itself.

Christian Horner's connection to TAG Heuer runs through Red Bull Racing's long-standing partnership with the brand, making this personal gift from Arnault a pointed gesture — one that merges corporate relationship-building with a genuine product statement. Horner, a central figure in the current Formula 1 narrative, gives the Monza CR5090.FN6001 immediate visibility at exactly the right venue.

As a freshly unveiled reference, retail pricing for the TAG Heuer Monza Flyback Chronometer CR5090.FN6001 has not yet been formally confirmed across all markets. Grey-market data is naturally absent this early. Collectors tracking carbon-cased, COSC-certified flyback chronographs at this specification level should expect positioning consistent with TAG Heuer's premium Carrera and Monaco tiers.
