Royal Tunku Ismail Ibni Sultan Ibrahim spotted wearing a Rolex

The sighting comes via the Crown Prince of Johor's own social media presence, where Tunku Ismail Ibni Sultan Ibrahim — known publicly as TMJ — was photographed wearing what is arguably the most opulent wristwatch in Rolex's current active lineup. The piece in question is the Rolex GMT-Master II reference 116769TBR, popularly known as the 'GMT Ice,' and its appearance on a reigning royal wrist is entirely fitting.

The Rolex GMT-Master II 116769TBR is constructed entirely in 18k white gold, from the 40mm Oyster case to the integrated Jubilee bracelet. What separates it from every other GMT-Master II is the factory diamond treatment: the fixed bezel is set with 48 baguette-cut diamonds totalling approximately 2.08 carats, the dial is paved with brilliant-cut diamonds, and baguette diamonds continue across the lugs and every link of the bracelet. The movement inside is Rolex's in-house Calibre 3186, a COSC-certified self-winding manufacture movement beating at 28,800 vph with a Parachrom hairspring and a 50-hour power reserve — serious mechanics beneath an extreme exterior.

The reference 116769TBR entered the Rolex catalogue as the unambiguous statement piece of the GMT-Master II family. Where the steel 116710LN or the Pepsi 126710BLRO represent the workhorse side of the GMT lineage — a tool watch born from a 1955 Pan Am pilot collaboration — the 'GMT Ice' repositions that same architecture as high jewellery. Rolex produced it in strictly limited quantities, and it has never been a watch you simply walk into an authorised dealer and purchase.

Tunku Ismail Ibni Sultan Ibrahim is the Crown Prince and military general of the state of Johor, Malaysia, and has cultivated a public profile that extends well beyond royal duties. He is an outspoken figure on social media with a well-documented passion for high-end horology, football, and fast cars. His choice of the GMT Ice over the hundreds of other exceptional watches available to him at this price point speaks to a preference for Rolex's factory craftsmanship rather than independent haute horlogerie.

On the market, the Rolex GMT-Master II 116769TBR commands a UK list price in excess of £440,000, placing it north of $550,000 USD at current exchange. Grey-market premiums on a piece this rare and this infrequently traded are essentially academic — transactions happen privately, and the 'GMT Ice' rarely appears at auction or through secondary dealers. When it does, expect prices that reflect both the intrinsic diamond and gold value and the cachet of owning the crown jewel of the Rolex sports catalogue.
