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

Crown Prince Ammar bin Humaid Al Nuaimi of Ajman has been photographed wearing one of independent horlogerie's most exclusive timepieces: an F.P. Journe Tourbillon Souverain finished in an exceptionally rare jade dial variant. The sighting underscores the continued appeal of Journe's haute horlogerie at the highest echelon of UAE royalty and international collectors.

The Tourbillon Souverain represents François-Paul Journe's definitive expression of tourbillon architecture. The watch houses the in-house calibre 1300.3, a manual-wind movement with chronometer certification and remarkable complication density: a constant-force tourbillon, power-reserve indicator spanning the upper dial, and a skeletonised balance wheel visible via exhibition caseback. The 40mm case measures approximately 12mm in thickness and is crafted from white gold, paired here with a blue alligator leather strap fitted with a white-gold folding clasp. Water resistance stands at 20 metres, typical for dress chronometers of this calibre. The dial—rendered in jade rather than the standard enamel or lacquer finishes—demands months of hand-finishing and represents a custom commission outside Journe's regular catalogue.

Jade dials from F.P. Journe occupy a rarefied collecting category, produced only for select clients and occasions. The use of natural or treated jade requires specialised dial fabrication, and fewer than a dozen examples likely exist in collector hands globally. The Tourbillon Souverain itself, in any finish, sees production limited to approximately 8–10 pieces annually, cementing its scarcity profile.

The pairing aligns with established patterns in Emirates royal watch collecting: preference for independent Swiss manufactures, tourbillon complications, and bespoke dial executions that signal exclusivity beyond list price alone. Crown Prince Ammar's acquisition reflects both horological connoisseurship and the resource required to commission Journe at the highest custom level.

Retail pricing for standard Tourbillon Souverain examples ranges from $2.2 to $2.8 million USD depending on dial finish and options. The jade variant, bespoke in nature, commands the reported $3.5 million valuation based on material rarity and custom labour. No secondary-market comparable data exists, as such pieces rarely surface for sale.
