Royal Ammar bin Humaid Al Nuaimi spotted wearing Patek Philippe

Sheikh Ammar bin Humaid Al Nuaimi, Crown Prince of Ajman and a figure regularly spotted in the orbit of serious horology, was recently photographed wearing what is arguably one of the most covetable references to emerge from Geneva in the last several years: the Patek Philippe perpetual calendar chronograph ref. 5270P-014, introduced at Watches & Wonders 2022.

The 5270 family sits at the apex of Patek Philippe's complicated watch catalogue, housing the manufacture Calibre CH 29-535 PS Q — a column-wheel, horizontal-clutch movement that took over a decade to develop and debuted in 2011. It beats at 28,800 vph, offers a 55-hour power reserve, and integrates a perpetual calendar module with instantaneous jumping date, day, and month displays alongside a leap-year indicator and moon phase. In the 5270P-014 variant, all of this sits beneath a lacquered green dial presented in a 40mm platinum case — a material combination that adds appreciable wrist presence and a cold, weighty authority that white gold cannot replicate.

The most technically notable detail of the 5270P-014 is precisely what it omits: for the first time in the reference's history, Patek Philippe removed the tachymeter from the chapter ring. The decision is deliberate and divisive among collectors. Traditionalists see it as a loss; others argue the clean bezel finally allows the richness of the green lacquer and the symmetry of the dial architecture to speak without distraction. The black crocodile strap with matching green stitching completes the presentation with restrained elegance.

Sheikh Ammar is no casual watch wearer. His public appearances have consistently showcased high-complication timepieces from the top tier of the market, and a platinum 5270 — particularly in this green dial configuration — signals genuine collector knowledge rather than acquired-on-advice acquisition.

The official retail price for the Patek Philippe ref. 5270P-014 stands at approximately $195,000 USD. On the secondary market, platinum perpetual calendar chronographs from Patek Philippe routinely command premiums, and the green dial 5270P has already attracted intense demand among collectors who understand exactly how rare an allocation for this reference truly is.
