Royal Pierre Casiraghi spotted wearing a Richard Mille

The Circuit de Monaco provided the backdrop for one of the more fitting celebrity watch sightings of the season. Pierre Casiraghi, grandson of Prince Rainier III and a member of the Monégasque royal family with genuine sailing credentials, was photographed courtside at the Formula 1 Grand Prix wearing a Richard Mille RM 60-01 Regatta Flyback Chronograph — a watch that, much like its wearer, operates comfortably at the intersection of sport and privilege.

The Richard Mille RM 60-01 was developed with serious offshore racing in mind. Its movement — a manual-winding caliber with flyback chronograph, regatta countdown timer, and function selector — sits inside a characteristic tonneau-shaped case engineered from grade 5 titanium, delivering extraordinary shock resistance with a weight that barely registers on the wrist. The skeletonized architecture exposes the full mechanical landscape, including the distinctive baseplate construction derived from Richard Mille's motorsport-informed engineering philosophy. The standout complication is the UTC hand, which serves a dual purpose: it functions as a second time zone indicator or, when used in conjunction with the rotating bezel and solar position, becomes a compass orientation tool — a genuinely useful feature when racing offshore in unfamiliar waters.

Among collectors, the RM 60-01 occupies a specific niche within Richard Mille's sprawling catalog. It is not the brand's most visually theatrical piece, but it is among the most functionally considered. The regatta complication is executed with the precision one expects from a brand that spent years supplying movements to Formula 1 and tennis, and the navigational utility of the UTC/compass function elevates it beyond a straightforward sports chronograph. Production numbers are limited, and the reference rarely surfaces at auction in unworn condition.

Pierre Casiraghi is not a passive ambassador for the sailing world. He has competed in major offshore events including the Rolex Fastnet Race and co-founded the sailing team Malizia. The RM 60-01 is, in that context, a working tool dressed in a $150,000 case — not a fashion statement.

At retail, the Richard Mille RM 60-01 Regatta Flyback Chronograph is listed at approximately $150,000. On the secondary market, examples in good condition with box and papers have traded at or slightly above that figure, reflecting steady demand for sport-complication Richard Mille references with clear functional purpose and limited availability.
