Royal Ammar bin Humaid Al Nuaimi spotted wearing a Audemars Piguet

The sighting occurred in a relaxed official setting, the Crown Prince of Ajman engaged in paperwork, his left wrist casually revealing one of Audemars Piguet's most coveted limited-edition creations. The watch in question is the Royal Oak Tourbillon Extra-Thin in a titanium-platinum boutique configuration, limited to just 50 pieces worldwide — a production run so small it effectively makes this an object of haute horlogerie scarcity rather than simply luxury.

At the heart of the watch beats Calibre 2924, a manually wound flying tourbillon movement measuring a remarkable 6.15mm in total height. The tourbillon cage completes one rotation per minute and sits prominently at 6 o'clock on the smoked blue 'Grande Tapisserie' dial — AP's signature small-square guilloché pattern that has defined the Royal Oak aesthetic since 1972. The combination of satin-brushed titanium for the case and integrated bracelet with polished platinum for the octagonal bezel creates a deliberate play of contrasting textures and materials, elevating this version well above the standard steel references.

From a collector standpoint, the Royal Oak Tourbillon Extra-Thin occupies rarefied territory. Its architecture traces directly back to the 50th-anniversary ethos of pushing the Royal Oak into complication territory without compromising the wafer-thin silhouette that defines the Extra-Thin sub-family. Titanium-platinum pairings in AP's lineup have historically commanded exceptional secondary market premiums, and a boutique-only run of 50 units places this reference firmly in the 'unobtainium' category for all but the most connected collectors.

Prince Ammar bin Humaid Al Nuaimi, Crown Prince of Ajman and a known connoisseur of fine timepieces, has been previously spotted in AP references — a pattern consistent with the Gulf royal tradition of treating haute horlogerie as a legitimate art form rather than mere status signalling. The choice of a titanium-cased piece speaks to a sophisticated palate: lighter on the wrist, technically superior, yet visually restrained.

At a listed price of approximately $140,000 USD, this boutique edition commands significant premium over the standard steel Royal Oak Tourbillon Extra-Thin. On the grey market, the combination of 50-piece limitation, titanium-platinum material pairing and boutique exclusivity means completed sales — when they occur at all — consistently exceed retail.
