Royal Joaan Bin Hamad Al Thani spotted wearing a Patek Philippe

Sheikh Joaan Bin Hamad Al Thani, the Prince of Qatar and a figure well known in international sporting and collecting circles, was photographed on the wrist with a Patek Philippe Aquanaut reference 5167A-012 — the coveted 'Singapore Edition' distinguished by its striking red tropical composite strap. For most observers it reads as a standard Aquanaut; for collectors, that strap changes everything.

The Patek Philippe Aquanaut 5167A-012 was released in October 2019 to coincide with the Watch Art Grand Exhibition held in Singapore, one of the manufacture's landmark travelling cultural events. The reference is built on the same architecture as the standard 5167A: a 40.8mm stainless steel case with the Aquanaut's signature rounded octagonal bezel and embossed 'Tropical' dial — here in a dark khaki-brown tone. The movement is Patek Philippe Calibre 324 S C, a self-winding manufacture ebauche beating at 28,800 vph with a 45-hour power reserve, offering both sweep seconds and a date complication. Water resistance is rated to 120 metres. What separates the 5167A-012 from its siblings is purely the red rubber strap and matching red pin buckle — a detail Patek executed with characteristic restraint, making the edition simultaneously bold and understated.

Production was capped at 500 pieces, allocated exclusively through Patek Philippe's authorised retail network in Singapore during the exhibition period. That constraint, combined with the single-city, single-event distribution model, immediately elevated the 5167A-012 to grail status among Aquanaut collectors and Patek enthusiasts globally. It has since become a benchmark piece for students of modern limited-edition strategy — proof that a single component change on an established reference, paired with strict scarcity, generates enduring desirability.

Sheikh Joaan is no casual watch wearer. The Qatari royal has been documented across a spectrum of serious horology, from vintage Patek to contemporary independent watchmaking. His choice of the 5167A-012 — wearing it casually rather than displaying it — reflects a collector's ease with genuinely rare material.

On the secondary market, the Singapore Edition Aquanaut commands a substantial premium over its list price of approximately £17,500 in the UK. Grey-market trading consistently places the reference well above £30,000, often higher depending on condition and provenance, with no sign of softening given the fixed supply and growing collector appetite for event-specific Patek references.
