Royal Ammar bin Humaid Al Nuaimi spotted wearing a Patek Philippe

Sheikh Ammar bin Humaid Al Nuaimi, Crown Prince of Ajman, was spotted wearing the then-freshly released Patek Philippe Aquanaut White Gold Khaki Green Reference 5168G shortly after its Baselworld 2019 debut — a sighting that placed the royal among the earliest high-profile wearers of one of that year's most discussed sport-luxury references.

The Patek Philippe Aquanaut 5168G measures 42.2mm in 18k white gold, housing the manufacture Calibre 324 S C automatic movement — a self-winding workhorse beating at 28,800 vph with a 45-hour power reserve, offering hours, minutes, seconds, and date. The embossed khaki green dial echoes the tropical aesthetic of the Aquanaut line, introduced in 1997 by designer Amédée Gordini as a younger, sportier counterpart to the Nautilus. The matching khaki composite strap with tropical-pattern embossing completes a coherent design language that is unmistakably Patek.

The 5168G occupies an interesting position within the Aquanaut family. While the stainless steel 5167A is perpetually allocated and effectively unobtainable at retail, the white gold 5168G offered a different kind of exclusivity at launch — theoretically purchasable for the right client, yet immediately scarce due to demand. The khaki green colorway felt genuinely novel in 2019, anticipating the broader industry shift toward green dials that would define the early 2020s. Collectors recognized this quickly.

Sheikh Ammar, a prominent figure in Emirati cultural and civic life, is known for an appreciation of refined horology consistent with the Gulf's deep collector culture. Choosing the 5168G at the moment of its release — rather than acquiring it after the hype solidified — speaks to a collector's instinct rather than trend-following.

On the secondary market, the Patek Philippe Aquanaut 5168G-010 commands a substantial premium over its retail price, with grey-market values reflecting sustained global demand. The reference has proven to be not merely a fashion moment but a durable collector piece, holding value firmly as the Aquanaut line continues to attract new generations of buyers.
