Entrepreneur Mukesh Dhirubhai Ambani spotted wearing a Rolex

Mukesh Ambani, chairman and managing director of Reliance Industries Limited and one of Asia's most prominent billionaires, was photographed wearing a vintage Rolex Cellini Reference 6623 in 18-karat yellow gold — a watch that sits at the quieter, more contemplative end of his reportedly extensive collection. The sighting is notable precisely because the Cellini Ref. 6623 is the antithesis of status-by-volume: it whispers where others shout.

The Rolex Cellini Ref. 6623 was produced in the late 1970s and into the early 1980s, representing a period when Rolex was actively developing its dress watch identity separate from its tool-watch legacy. The case is slim and round, crafted in 18-karat yellow gold, housing the hand-wound Rolex caliber 1600 movement — a reliable, no-frills manual-wind movement with a 42-hour power reserve. The dial on the Ref. 6623/8 variant features a clean, minimalist layout consistent with the Cellini line's philosophy of restraint. Lug width typically runs at 26mm, making it a genuinely elegant wrist presence rather than a bold statement piece.

Among vintage Rolex collectors, the Cellini references from this era occupy an interesting niche. They are often overlooked by buyers chasing Daytonas or Submariner variants, which means they have historically traded at accessible price points relative to their gold content and manufacture quality. The Ref. 6623 in particular is appreciated by connoisseurs who understand that Rolex's dress watch production required the same metallurgical precision and quality control standards as its sport references — just applied toward different aesthetic ends.

Ambani's choice of this specific watch is contextually interesting. As the head of a conglomerate with revenues exceeding $100 billion, he has access to virtually any timepiece on earth. Selecting a 40-plus-year-old yellow gold Rolex dress watch — modest in size, hand-wound, and visually unassuming — suggests a collector's sensibility rather than pure display.

On the current grey market, the Rolex Cellini Ref. 6623 in yellow gold trades in the $7,000–$9,000 range depending on condition, dial originality, and box and papers presence — representing genuine value for an 18-karat gold Rolex with historical depth.
