Royal Ammar bin Humaid Al Nuaimi spotted wearing a Greubel Forsey

At a formal gathering, Sheikh Ammar bin Humaid Al Nuaimi, Crown Prince of Ajman and a known connoisseur of serious horology, was photographed with what is unmistakably a Greubel Forsey GMT Sport in titanium on his wrist — a watch limited to just eleven examples worldwide. The sighting is notable not merely for the watch's scarcity, but because it confirms the Crown Prince's preference for independent watchmaking at its most uncompromising.

The Greubel Forsey GMT Sport represents the Geneva atelier's attempt to bring its most complex architecture into a sportier, more wearable format. The 45mm titanium case pairs with a black rubber strap and features a bidirectional rotating bezel engraved with the brand's philosophical tenets — 'Originalité, Bienf acture, Architecture, Perfection' — visible clearly in the reference image. The dial is a masterclass in organised complexity: a 24-second tourbillon inclined at 25° occupies the upper right, a hand-engraved rotating earth globe at centre-lower provides the GMT second timezone at a glance, and a power-reserve indicator rounds out the display. The calibre GF03TG delivers approximately 72 hours of autonomy.

Greubel Forsey co-founders Robert Greubel and Stephen Forsey developed the inclined tourbillon concept as a genuine horological argument — the 25° inclination subjects the escapement to constantly varying gravitational positions, theoretically improving rate performance beyond what a flat tourbillon achieves. That philosophy, combined with the hand-finishing standards of their Secret Signature movement architecture, places this watch in a category occupied by almost no one else.

From a collector standpoint, eleven pieces is not a marketing number — it reflects the genuine production capacity of a small atelier where each movement requires thousands of hours of hand-work. Prior GMT Sport references in white gold and titanium have traded significantly above retail on the secondary market, with titanium variants commanding premiums due to their lighter wearability and relative rarity within an already scarce production run.

Sheikh Ammar's taste in watches has long tracked the independent watchmaking scene, and this sighting reinforces that trajectory. At a UK list price of £380,000 — approximately $480,000 at current exchange — the Greubel Forsey GMT Sport Titanium is not a watch worn for visibility; it is worn for the same reason it was made: a genuine commitment to the discipline of timekeeping at its highest level.
