Royal Ammar bin Humaid Al Nuaimi spotted wearing a Rolex

Crown Prince Ammar bin Humaid Al Nuaimi of the Emirate of Ajman was recently observed wearing a stainless steel Rolex GMT-Master reference 1675 fitted with an all-blue 'Blueberry' bezel insert — one of the most elusive and genuinely scarce configurations within the entire GMT-Master lineage. The sighting, casual in setting yet significant to any serious collector, underscores the continued relevance of vintage Rolex sport references among those with both the means and the knowledge to seek them out.

The GMT-Master ref. 1675 was produced from 1959 through 1980, serving as Rolex's primary dual-timezone tool watch throughout that era. Powered by the automatic Calibre 1560 in its earlier iterations and later the Calibre 1575 — both self-winding movements with a 48-hour power reserve — the 1675 was built around a 40mm Oyster case in stainless steel, fitted with a bidirectional rotating bezel carrying a 24-hour graduated insert. The standard configuration used the now-iconic red-and-blue 'Pepsi' insert. The all-blue 'Blueberry' variant diverges sharply from that norm.

The origin of the Blueberry insert remains a subject of genuine horological debate. The prevailing theory holds that the monochromatic blue configuration was developed for military or aviation clients who required unambiguous AM/PM differentiation at a glance — the single-color format eliminating any potential misreading of the two-tone bezel under low-light or high-stress conditions. Documentation is sparse, which is precisely why confirmed examples from the 1980s production window, such as the one worn by the Crown Prince, carry exceptional weight among specialists.

Ammar bin Humaid Al Nuaimi is a figure known for cultivated taste across architecture, culture, and the arts. His choice of a technically obscure, visually understated vintage Rolex rather than a contemporary high-complication piece speaks to a collector sensibility that prioritizes provenance and rarity over spectacle — a distinction that separates true enthusiasts from status buyers.

On the current grey market, the Rolex GMT-Master ref. 1675 in Blueberry configuration commands approximately $50,000 in stainless steel, a significant premium over standard Pepsi examples of the same reference. Demand has been reinforced by the broader vintage Rolex market's sustained strength and the growing scholarly attention paid to military-specification variants. Retail pricing is not applicable given the watch's vintage status.
