Royal Mohammed Reza Pahlavi spotted wearing a Rolex

Among the watches documented on the wrist of Mohammed Reza Pahlavi — Shah of Iran until the 1979 revolution — the Rolex reference 1831 in platinum stands apart as a singular artifact of mid-twentieth-century royal collecting. The Shah was photographed wearing this piece during his reign, and its subsequent appearance at Phillips Watches in 2016 transformed it from a personal memento into a landmark horological event.
The Rolex ref. 1831 belongs to a lineage of dress watches produced by Rolex during the 1950s and 1960s, characterized by clean, restrained dials and classically proportioned 36mm cases. Platinum examples from this era are exceptionally scarce; Rolex reserved the noble metal almost exclusively for bespoke commissions and presentations to heads of state, royalty, and diplomatic figures. The navy dial on this particular reference adds a further layer of rarity — most surviving examples in any metal present in silver or champagne tones. The movement within is a period-correct manually wound Rolex caliber, regulated to the standards expected of the manufacture's top-tier references of the day.
From a collector's perspective, the Rolex ref. 1831 in platinum occupies rarefied territory. Provenance is everything in high-end vintage Rolex collecting, and few provenances carry more weight than direct royal ownership. The piece's 2016 Phillips result — $225,000 — reflected not just the watch itself but the irreplaceable historical narrative attached to it. It remains one of the more significant Rolex auction results for a non-sports reference from that decade.
Mohammed Reza Pahlavi was a serious and knowledgeable watch collector, and his tastes ran to the finest Swiss houses. His collection spanned Patek Philippe, Vacheron Constantin, and Rolex, often in precious metals and with unique specifications ordered through royal channels. The ref. 1831 in platinum exemplifies how he used horology as both personal expression and diplomatic currency.
No retail price exists for this reference in its current form — it was never a catalogue item in the conventional sense. The 2016 Phillips hammer price of $225,000 remains the definitive market reference point, and any future appearance at auction would almost certainly surpass it given the continued appreciation of royal-provenance Rolex pieces in the current market.
