Meet Rolex's New "Root Beer" Tiger Iron GMT-Master-II Watch
The GMT-Master II Rolex pushes into more rarefied territory with a rare new Tiger Iron stone face, dubbed "Root Beer," turning a tool-watch icon into a piece that sits as much in the world of jewelry as in travel horology. The combination of brown and black ceramic bezel, warm rose-gold case, and richly banded stone surface gives this 40 mm GMT a striking visual depth that distinguishes it clearly from the standard black-dial variant already in the catalog.
Tiger Iron as a material is central to the character of this edition. Described as a semi-precious gemstone formed from a natural blend of tiger’s eye, red jasper, and black hematite, it creates layered, earthy bands of gold, red, and deep grey that shift with the light. Each slice of stone is unique, so no two watches present exactly the same pattern, which adds a degree of individuality unusual in a regular-production GMT-Master II and reinforces the piece’s position as an exclusive 2025 release.

Around that dial sits the signature two-colour Cerachrom bezel insert in brown and black, the detail that has long anchored the “Root Beer” nickname among collectors. The bi-directional rotatable 24-hour bezel, with moulded numerals and graduations in ceramic, allows the dedicated 24-hour hand to display a second time zone while the local hour hand can be adjusted in one-hour jumps. The bezel’s warm brown half resonates with the watch’s golden streaks, while the black segment ties in with the deep tones of the stone and the gloss of the Chromalight-filled hour markers. (Rolex)
The case architecture follows the modern Oyster template: a 40 mm Everose gold case with a monobloc middle, screw-down case back, and Triplock winding crown rated to 100 metres of water resistance. Scratch-resistant sapphire protects the dial, with the familiar Cyclops lens over the date at 3 o’clock for quick legibility. The overall profile balances presence and practicality, retaining the proportions expected of a current-generation GMT-Master II while the solid 18 kt Everose construction underscores the model’s luxury positioning.
Inside, the watch is powered by the manufacture calibre 3285, a self-winding movement with GMT function that embodies Rolex’s contemporary technical standards. The calibre offers a power reserve of approximately 70 hours, a paramagnetic blue Parachrom hairspring, high-performance Paraflex shock absorbers, and a bidirectional Perpetual rotor for efficient winding. Its Superlative Chronometer certification after casing, with a precision of −2/+2 seconds per day, positions this reference as a high-performance travel watch as much as a precious-metal statement piece.
Functionality is oriented around real-world travel. The movement’s independently adjustable local hour hand allows time-zone changes without stopping the seconds or disturbing the home-time indication on the 24-hour scale, a feature designed for frequent flyers and international business use. The stop-seconds mechanism still permits precise time setting when needed, and the instantaneous date change tied to the local hour keeps the calendar consistent with where the wearer actually is, rather than with the reference time.
Legibility remains a priority despite the watch’s decorative nature. The Tiger Iron surface hosts applied hour markers and hands filled with Rolex’s Chromalight luminous material, engineered for a long-lasting blue glow in low light. The contrast between the polished Everose surrounds, the dark Ultra Black-style depth of the stone, and the blue-emitting lume ensures that the watch can be read quickly in aircraft cabins, city streets at night, or dim interiors, maintaining the GMT-Master II’s reputation as a functional instrument.
The watch is fitted with an Everose gold Oyster bracelet, composed of three-piece solid links designed to balance robustness and comfort. An Oysterlock folding safety clasp guards against accidental opening, while the Easylink comfort extension link allows the wearer to increase bracelet length by approximately 5 mm on demand, accommodating temperature changes or wrist swelling without the need for tools. This combination of micro-adjustability and solid precious-metal construction reinforces the sense that the watch is built for both daily wear and long-term ownership.
In aesthetic terms, the Root Beer Tiger Iron edition occupies an intersection between vintage inspiration and contemporary luxury. The brown-and-black bezel recalls earlier bi-colour GMT designs, but the Everose case and bracelet, the glossy ceramic, and the gemstone dial take the concept in a more opulent direction. The result is a watch that still clearly reads as a GMT-Master II at a glance, yet communicates rarity and craft through its materials, particularly in the way the watch’s layered striations play against the warm metallic tones of the case and bracelet.
Positioned within the broader GMT-Master II family, the Everose Root Beer with Tiger Iron serves as a high-end, stone-dial counterpoint to more utilitarian steel models with ceramic bezels in black-and-blue or red-and-blue. It retains the core travel-time functionality and robustness that define the line, yet by pairing a semi-precious dial with a fully Everose gold case and bracelet, it speaks directly to collectors who want a GMT that stands apart not through complications, but through materials and finishing.
