Entrepreneur GMK spotted wearing a Richard Mille

Monaco has long been the natural habitat of extreme horology, and it was there that entrepreneur GMK was recently spotted wearing what may be the rarest wristwatch to surface in public this year: the Richard Mille RM 35-03 Automatic Rafael Nadal, released in 2021 and believed to have been seen on fewer than six wrists worldwide.

The RM 35-03 is the fourth evolution of Richard Mille's RM 035 lineage, a family born from the brand's long-standing partnership with tennis legend Rafael Nadal and engineered to survive the brutal torque and shock loads of professional clay-court play. The 43 mm case is constructed from Quartz TPT — a proprietary composite material produced by layering silica filaments in a resin matrix at alternating angles before compression, yielding a structure stronger than titanium at a fraction of the weight. The result is a case that weighs just grams and displays the marbled, almost geological surface texture the material is known for. The CRMA2 automatic calibre inside operates at 28,800 vph, offers 55 hours of power reserve, and incorporates a variable geometry rotor — but the RM 35-03 goes further by making that rotor user-adjustable directly on the wrist, a world first for any wristwatch at the time of its release. Wearers can dial in rotor resistance to suit their personal activity level, optimising winding efficiency without opening the case.

Among collectors, the RM 035 series occupies a particularly coveted corner of the Richard Mille catalogue. The Nadal connection is genuine rather than cosmetic — early iterations were literally stress-tested during Grand Slam matches — and each successive reference has introduced a meaningful technical step rather than a simple cosmetic refresh. The RM 35-03 represents the series at its most technically ambitious.

GMK has cultivated a reputation for acquiring objects that sit at the outer edges of their respective categories, from hypercars to haute horlogerie. The RM 35-03 on his wrist fits that profile precisely — not a watch purchased for visibility alone, but one whose engineering credentials are as serious as its price tag.

On the secondary market, the Richard Mille RM 35-03 Rafael Nadal commands approximately $900,000, a figure that reflects both its technical novelty and its near-total absence from public circulation. Richard Mille does not publish an official retail price for pieces at this allocation tier, but grey-market data consistently places it in that range. At this level, the watch functions less as a luxury accessory and more as a portable asset.
