Royal Tunku Ismail Ibni Sultan Ibrahim spotted wearing Rolex

The Crown Prince of Johor has long used his social media presence to showcase a collection that would embarrass most private dealers, and his latest sighting raises the bar once again. Tunku Ismail Ibni Sultan Ibrahim — widely known as TMJ — was photographed wearing the Rolex Cosmograph Daytona reference 116568BR, a factory-set gem piece distinguished by a vivid green dial and a bezel pavéd with 24 baguette-cut diamonds.

The 116568BR sits within Rolex's Daytona precious-metal tier, constructed entirely in 18-karat yellow gold. Its 40mm case houses the manufacture caliber 4130, a column-wheel, vertical-clutch chronograph movement that Rolex developed entirely in-house and introduced in 2000. The caliber 4130 runs at 28,800 vph, offers approximately 72 hours of power reserve, and is widely regarded as one of the most robust and accurate chronograph movements in series production. The green dial — a color Rolex has deployed selectively across its gold sports references to considerable collector effect — provides a sharp chromatic contrast against the yellow gold sub-registers and the glittering baguette bezel.

Factory gem-set Daytonas occupy a specific and deliberately scarce corner of the Rolex catalog. Unlike aftermarket diamond modifications, which can void warranties and dilute resale value, the 116568BR leaves Geneva fully dressed. Rolex's in-house gem-setting atelier selects, cuts, and sets each stone to its own tolerances, and the result carries the manufacture's full certification. Among collectors, this distinction matters enormously — a factory-set reference retains provenance that no third-party jeweler can replicate.

TMJ is no casual watch wearer. The Crown Prince's Instagram feed reads as a curated horological diary spanning Royal Oak Tourbillons, independent complications, and ultra-rare Rolex pieces, making him one of the most-watched wrists in Southeast Asia. His choice of the 116568BR underscores how royalty and institutional Rolex prestige still find common ground even at the apex of the market.

At a UK list price of approximately £50,000 — translating to roughly $63,000 USD at current exchange rates — the Daytona 116568BR is not an allocated steel sports reference; it is an invitation-tier piece that rarely sits in display cases long enough to be photographed. On the secondary market, yellow gold gem-set Daytonas have held their value with quiet consistency, typically trading at or modestly above retail, a dynamic that reflects genuine demand rather than speculative fever.
