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

At a crowded arena-style event in the UAE, Sheikh Ammar bin Humaid Al Nuaimi, Crown Prince of Ajman, was photographed with what is almost certainly one of the rarest and most consequential independent watchmaking pieces of the modern era on his wrist: a platinum F.P. Journe Tourbillon Souverain Remontoir d'Egalité from the inaugural production series of 1999 to 2003.

The Tourbillon Souverain was not merely F.P. Journe's debut commercial wristwatch — it was the technical manifesto of a watchmaker who had spent years perfecting the remontoir d'égalité, a constant-force mechanism that delivers a regulated, equal impulse to the escapement every ten seconds. This engineering principle, visible through the distinctive sub-dial layout on the champagne-lacquered brass dial, is annotated directly on the dial face: 'Remontoir d'Egalité' and 'Invenit et Fecit' — Latin for 'invented and made,' Journe's personal signature of complete authorship. The platinum case of the early series measures 38mm, housing the manually wound Calibre 1304 with a flying tourbillon at 9 o'clock and a subsidiary seconds dial at 3 o'clock.

The 1999–2003 platinum variant with brass movement plates — before Journe transitioned to rose and red gold movements — is the most sought-after configuration among serious Journe collectors. The brass plate gives the movement a warm, aged aesthetic that later iterations replaced with 18k gold. Production numbers for this specific combination are estimated at well under 200 pieces worldwide, making each example a genuine collector's rarity rather than a manufactured scarcity.

Sheikh Ammar is a known connoisseur of serious independent horology, and this choice of watch speaks to a discerning collector sensibility rather than mere status signaling. The Tourbillon Souverain predates the F.P. Journe hype cycle by nearly two decades — owning an early example signals genuine knowledge of the brand's foundational history.

On the secondary market, early platinum Tourbillon Souverain examples have achieved prices between $500,000 and $700,000 USD at major auction houses including Phillips and Christie's, driven by the combination of historical importance, extreme scarcity, and the surging global demand for early F.P. Journe references. This is a watch that defines a category.
