Basketball player LeBron James spotted wearing a Richard Mille

LeBron James was recently photographed wearing a Richard Mille RM 11-03 Automatic Flyback Chronograph fitted on a green rubber strap — one of the brand's most technically loaded sport-complication references and a consistent fixture on the wrists of athletes who take their watches as seriously as their performance metrics.

The RM 11-03 is powered by Richard Mille's in-house RMAC2 calibre, a skeletonised automatic movement with a variable-geometry rotor that allows the wearer to tune winding efficiency based on activity level — a genuinely useful feature for someone logging 35 minutes of high-intensity NBA floor time. The movement delivers hours, minutes, running seconds, a flyback chronograph, a 60-minute countdown timer at 9 o'clock, a 12-hour totalizer, and an oversize date and month indicator. Power reserve sits at approximately 55 hours. The case, typically rendered in grade 5 titanium or NTPT Carbon depending on the variant, is engineered to tolerances borrowed directly from Formula 1 and aerospace, keeping weight negligible despite the complication density.

The RM 11-03 succeeded the RM 011 in 2018, refining the case architecture and movement finishing while retaining the annual calendar and flyback functionality that made the original a landmark in high-complication sport watchmaking. Collectors regard the 11-03 as the more resolved expression of that lineage — tighter tolerances, improved legibility, and better integration between the baseplate and the bridges visible through the open dial.

For LeBron James, the RM 11-03 is consistent with a well-documented affinity for Richard Mille. He has appeared publicly in multiple references from the brand over the years, and the choice of a green rubber strap adds a personalised, low-key flourish to a watch that already commands attention on its own terms. The green strap quietly nods to his Lakers-adjacent identity without being literal about it.

At a retail price of $172,500, the Richard Mille RM 11-03 is already positioned at the sharp end of the luxury sports watch market. On the grey market the reference trades at roughly $350,000 — a premium of more than 100 percent that reflects both restricted supply and the crossover appeal the RM 11-03 enjoys among athletes, collectors, and investors alike.
