Royal Lamia Bint Majed Saud Alsaud spotted wearing a Patek Philippe

Photographed for the cover of Vogue Arabia, Princess Lamia Bint Majed Saud Alsaud — Secretary General of the Alwaleed Philanthropies Foundation — was spotted on her wrist with one of the most coveted complication watches in current production: the Patek Philippe Perpetual Calendar Chronograph reference 5271P-010 in platinum, adorned with 58 baguette diamonds set across the bezel and lugs, and a single baguette diamond marker at 12 o'clock.

The 5271P-010 houses Calibre CH 29-535 PS Q, Patek Philippe's in-house column-wheel chronograph movement with a perpetual calendar module. The movement operates at 28,800 vph, offers a power reserve of approximately 65 hours, and achieves a level of finishing — chamfered bridges, Côtes de Genève, bevelled levers — that satisfies even the most exacting AHCI standards. The 41mm platinum case presents a black lacquered dial with applied baton indices, a moonphase display at 6 o'clock flanked by date numerals, and day/month apertures positioned symmetrically at 10 and 2 o'clock. The tachymeter scale on the outer rehaut reminds collectors that this is, above all, a functioning chronograph of the highest order.

Reference 5271P was introduced as a successor to the legendary 5970, maintaining the same core philosophy — grande complication in an elegantly proportioned case — while integrating Patek's newest column-wheel chronograph calibre. The diamond-set 5271P-010 variant sits at the apex of the reference family, occupying the intersection of haute joaillerie and serious horology. It is the kind of watch that appeals to collectors who refuse to choose between technical depth and wearable luxury.

Princess Lamia's public profile aligns naturally with the 5271P's positioning. As the head of one of the Arab world's most visible philanthropic institutions, she regularly appears at events where personal presentation carries institutional weight. Wearing a watch at this level communicates a considered, long-term approach to collecting rather than conspicuous spending — the 5271P is not a watch bought on impulse.

At list price, the Patek Philippe Perpetual Calendar Chronograph 5271P-010 retails at approximately $289,700 USD. On the secondary market, platinum perpetual calendar chronographs from Patek Philippe — particularly diamond-set examples in excellent condition with box and papers — routinely trade above retail, with auction results for comparable references clearing $350,000 to $450,000 depending on provenance and condition. Allocation remains tightly controlled, making grey-market access difficult and valuations robust.
