Royal Ammar bin Humaid Al Nuaimi spotted wearing a F.P. Journe

Spotted during what appears to be a visit to an ornate interior venue, Crown Prince of Ajman Sheikh Ammar bin Humaid Al Nuaimi raised his phone to capture a photograph — inadvertently revealing one of the most coveted and technically complex wristwatches in contemporary horology. On his wrist sat an F.P. Journe Tourbillon Souverain in platinum, fitted with the extraordinarily rare red grand feu enamel dial. The contrast of the vivid crimson against the cool platinum case is immediately recognizable to any serious collector.

The Tourbillon Souverain is the cornerstone of F.P. Journe's manufacture and one of the most mechanically sophisticated watches in independent horology. Its movement features a remontoir d'égalité — a constant-force device that rewinds every 20 seconds to deliver a perfectly equal impulse to the tourbillon — combined with a seconds morte (dead-beat seconds) subdial. The power reserve indicator arcs across the upper portion of the dial, while the time display is relegated to a subsidiary dial at 3 o'clock, giving the movement's architecture visual primacy. The hand-wound movement runs on an 80-hour power reserve and is crafted entirely in-house at Journe's Geneva manufacture.

From a collector standpoint, the red dial Tourbillon Souverain sits at the apex of F.P. Journe desirability. Journe introduced colored enamel dials — including blue, green, and red — for a select number of references, with red being the most visually dramatic and statistically the rarest. Platinum cases paired with red enamel represent the ultimate configuration, produced in single-digit or low double-digit quantities. These watches rarely surface at auction; when they do, they command prices that dwarf original retail.

Sheikh Ammar bin Humaid Al Nuaimi, Crown Prince of Ajman and a well-documented connoisseur of independent watchmaking, is no stranger to horological rarities. His collection reportedly includes multiple F.P. Journe references alongside pieces from other independent makers. Wearing the Tourbillon Souverain in a casual, mobile context speaks to the confidence of a collector who treats these objects as instruments rather than display pieces.

On the open market, platinum red-dial examples of the Tourbillon Souverain have achieved prices in the range of $350,000–$450,000 USD depending on provenance and condition. Original retail for platinum Tourbillon Souverain references was approximately $180,000–$220,000, meaning secondary market premiums of 2x or more are now standard. Demand continues to outpace supply significantly.
