Entrepreneur Oweis Zahran spotted wearing a Richard Mille

Oweis Zahran, the entrepreneur and prominent figure in luxury collecting circles, was recently seen with what is arguably one of the most mechanically audacious tourbillons in existence strapped to his wrist: the Richard Mille RM 53-01 Tourbillon 'Pablo Mac Donough.' With a production run of just 30 pieces and a price tag hovering around $900,000, this is not a watch one wears casually — yet that contradiction is precisely the point Richard Mille has always made.

Developed in partnership with Argentine polo champion Pablo Mac Donough, the RM 53-01 addresses a very specific engineering problem: how do you build a tourbillon that survives the game of polo? The answer was a movement suspended on a series of Dyneema cables — the same ultra-high-molecular-weight polyethylene fiber used in bulletproof vests and mooring lines for supertankers. This suspension system allows the entire movement to absorb lateral shocks and vibrations that would shatter a traditional lever escapement. Richard Mille paired this with a Carbon TPT case, a material formed from hundreds of layers of carbon filament laid at 45-degree angles and infused with resin, producing a structure stronger than titanium at a fraction of the weight.

The openworked dial architecture exposes the tourbillon cage and baseplate in full, with the signature spline screws visible across the skeletonized movement — a detail that reads as both technical statement and aesthetic signature. The manual-winding caliber runs at 21,600 vph and offers approximately 70 hours of power reserve, housed in a case measuring 49.94 mm × 42.71 mm.

For collectors, the RM 53-01 occupies a rare tier even within Richard Mille's own catalog. Its extreme limitation, the legitimacy of its sport-engineering brief, and the direct involvement of a world-class athlete give it a coherent narrative that many limited editions lack. It is consistently cited alongside the RM 27 series as a benchmark of the brand's technical ambition.

On the grey market, verified examples of the RM 53-01 trade well above retail, with recent transactions reported in the $1.1 million to $1.4 million range depending on condition and provenance. Zahran's choice to wear rather than vault this piece speaks to a collector philosophy that prioritizes the watch as an object of use — the spirit the RM 53-01 was literally built for.
