Tennis player Gaël Monfils spotted wearing a Patek Philippe

Patek Philippe's perpetual calendar lineage is among the most storied in haute horlogerie, and catching Gaël Monfils — one of tennis's most charismatic and style-conscious players — wearing a reference 5140G-010 is precisely the kind of sighting that validates the model's crossover appeal beyond traditional watch collectors. The deep anthracite sunburst dial, flanked by a black alligator strap and white gold case, is as composed off the court as Monfils is explosive on it.

The 5140G-010 is powered by Patek Philippe's Calibre 240 Q, a micro-rotor self-winding movement of exceptional pedigree. At just 27.5mm in diameter and 3.88mm thick, it is one of the most refined perpetual calendar movements in existence, offering instantaneous date correction and a moonphase display accurate to one day every 122 years. The 37.2mm white gold case gives the watch an elegant, almost understated presence that belies the mechanical complexity within — a hallmark of the Geneva Seal-certified manufacture.

The reference 5140 succeeded the legendary 3940 in 2000 and has itself become a modern cornerstone of the Grand Complications collection. The G suffix denotes white gold, while the -010 variant specifies the grey-toned anthracite dial, widely regarded by collectors as the most versatile and contemporary execution of this reference. Unlike many perpetual calendars, the 5140 requires no pushers to correct the calendar — operations are performed via the crown alone.

Monfils, ranked among the ATP's most entertaining players for over two decades, is no stranger to fine watches and has been spotted across a range of high-end timepieces. His choice of the 5140G reflects a collector sensibility that values understated complication over flashy aesthetics — the watch does not announce itself, yet those in the know immediately recognise its significance. The silver Crown Hearts bracelet alongside it adds a streetwear-adjacent tension to an otherwise formal timepiece.

On the secondary market, the 5140G-010 commands a substantial premium over its already considerable retail price. Grey-market demand for white gold perpetual calendar references from Patek has intensified since 2020, with waitlists at authorised dealers extending indefinitely. For collectors, this sighting is a reminder that the 5140G remains one of the most intellectually satisfying — and increasingly elusive — watches in modern production.
