Jeff Bezos is no stranger to the world of rare collectibles, but his latest wrist choice turned more heads than any new investment or business move. During a dinner outing in Miami with his wife, the Amazon founder was seen wearing a Richard Mille RM 27-05 Flying Tourbillon Rafael Nadal, a watch that costs an astonishing $2.4 million on the market. The timepiece, limited to only 80 pieces, effortlessly complemented Bezos’s understated outfit of a black shirt and dark gray jeans. It was a look that balanced quiet confidence with a clear message of refined taste.
Previously, Jeff was mostly seen wearing relatively affordable watches, such as the Ulysse Nardin Dual Time, priced at nearly $7,700. It was his wife, Lauren Sánchez, who has long shown a love for rare and extravagant timepieces. A few months ago, she was spotted wearing a dazzling $290,000 Richard Mille RM 07 ‘Intergalactic Dark Night,’ a watch known for its gem-set case and bold design. Is it the stylish diva who got Bezos to up his watch game? Being the second richest person on the planet, he can easily afford to build a massive collection of some of the rarest and most expensive watches ever created.
Launched in 2024, the RM 27-05 marks the final creation in Richard Mille’s celebrated lightweight Rafael Nadal series. The collection, which began in 2010 with the RM 027, redefined what was possible in sports watch engineering. Over 14 years, it evolved into a showcase of extreme innovation, constantly pushing the limits of lightness and strength. The RM 27-05 stands as the culmination of that journey, bringing together every technical breakthrough developed across the series into one ultralight masterpiece.
At just 11.5 grams without the strap, the RM 27-05 is the lightest mechanical watch ever produced by Richard Mille. Its case is crafted from Carbon TPT B.4, a cutting-edge composite material derived from Formula 1 engineering. Compared to standard Carbon TPT, this new formulation is 4 percent denser, 15 percent stiffer, and 30 percent more resistant.
This allows Richard Mille’s engineers to machine even thinner components while retaining immense rigidity. The result is a monobloc case structure so strong and refined that it does not require traditional screws to hold the movement in place.
Inside beats the manual-winding RM27-05 caliber, a flying tourbillon movement that reflects the brand’s obsession with mechanical artistry. The movement measures only 2.12 millimeters in thickness and consists of 22 jewels. It offers a 55-hour power reserve and operates at 21,600 vibrations per hour. Its skeletonized construction showcases the complexity of the design while minimizing unnecessary mass. Every part has been optimized for strength-to-weight efficiency, down to the smallest screw. The tourbillon itself is mounted on a system of precision bearings, eliminating the need for an upper bridge and further reducing weight.
The movement is secured inside the case at six exact support points, ensuring maximum rigidity and shock absorption. This remarkable architecture allows the RM 27-05 to withstand forces of up to 300 gs, a record for a tourbillon-equipped watch. The entire assembly measures a slender 7.20 millimeters in height, giving it a sleek profile despite its technical intensity.
Aesthetically, the RM 27-05 is restrained yet unmistakably modern. The textured black Carbon TPT finish gives it an industrial elegance, while the skeletonized dial reveals the wishbone-shaped bridge that dominates the movement. Unlike earlier Nadal models that featured bright colors and flamboyant accents, this final edition focuses on pure technical performance. It feels like a closing statement to a legendary chapter in the partnership between Richard Mille and Rafael Nadal.
The RM 27-05 is not about diamonds or decoration; it is about mastery, precision, and innovation distilled into wearable form. On Bezos’s wrist that evening in Miami, the world’s second-richest man wore more than a watch. He wore the ultimate expression of modern watchmaking. It’s a fusion of science, art, and ambition that defines the spirit of Richard Mille.
