Royal Crown Prince and Regent of Johor spotted wearing a Patek Philippe

During a recent appearance, the Crown Prince and Regent of Johor was photographed wearing one of Patek Philippe's most exclusive modern creations: the Nautilus Ref. 5711/111P-001 in platinum with a full sapphire bezel. The sighting marks a significant moment in luxury watchmaking, as this particular reference remains extraordinarily difficult to acquire through official channels or the secondary market.

The Nautilus Ref. 5711/111P-001 builds on the architecture of the legendary sports watch introduced in 1976, but elevates it into high-jewelry territory. The case measures 40mm in diameter and is crafted entirely from platinum, a material reserved for Patek Philippe's most prestigious creations. The octagonal bezel—the defining design element of the Nautilus—is set with 32 individually cut blue sapphires in baguette form, totaling approximately 4 carats of fine gemstones. The dial features a sunburst finish in deep charcoal or black, depending on light conditions, with blue sapphire hour markers and a date window at 3 o'clock. The integrated bracelet, also in platinum with polished and brushed finishing, completes the luxury sports aesthetic without sacrificing wearability.

The movement powering this reference is Patek Philippe's Calibre 324, a self-winding mechanical movement with approximately 45 hours of power reserve and 324 components. Water resistance stands at 120 meters, adequate for daily wear despite the watch's jeweled status. The Ref. 5711/111P-001 represents an intentional departure from steel sports watches; Patek Philippe produces these sapphire-set Nautilus pieces in extremely limited quantities, making them among the rarest contemporary Nautilus variants. Unlike the more accessible stainless-steel models, sapphire-bezel platinum versions command serious collector attention and form part of high-net-worth acquisition strategies rather than typical enthusiast collecting.

The Crown Prince's choice reflects a collector's understanding of Patek Philippe's hierarchy and the singular position occupied by sapphire-set sports watches in modern horology. The Nautilus Ref. 5711/111P-001 represents a deliberate fusion of Gérald Genta's original sports-watch design language with traditional high-jewelry craftsmanship—a combination few watchmakers execute successfully.

Market pricing for the Platinum Nautilus Ref. 5711/111P-001 reflects its rarity and exclusivity. Secondary market estimates place the reference near $900,000 USD, though transactions remain infrequent due to limited availability. Patek Philippe has not publicly disclosed production numbers for this specific variant, but collector intelligence suggests production remains in the low hundreds across several years of manufacture. Authorized dealer waitlists for sapphire-set Nautilus models extend well beyond five years, making grey-market acquisition the primary avenue for interested collectors.
