GMT-Master II 'Root Beer'

Rolex GMT-Master II 126715CHNR

The Rolex GMT-Master II – Ref. 126715CHNR, widely known as the modern “Root Beer,” elevates the historic brown-and-black GMT aesthetic into a full 18 ct Everose gold execution. Introduced in 2018, this reference combines tool-watch aviation heritage with precious-metal presence, offering dual-time functionality in a luxurious format.

The 40 mm Everose gold Oyster case is paired with a bidirectional rotatable bezel fitted with a two-tone brown and black Cerachrom ceramic insert, featuring moulded 24-hour graduations with platinum-filled numerals. The classic black dial — also available in a rare tiger’s eye variant (m126715chnr-0002) — showcases applied hour markers and hands with long-lasting Chromalight luminescence, ensuring clarity across time zones.

Built on robust Oyster architecture, the watch includes a Triplock screw-down crown, scratch-resistant sapphire crystal with 2.5× Cyclops date magnifier, and a solid caseback ensuring 100 meters of water resistance.

At its core beats the in-house Rolex Calibre 3285, a self-winding movement operating at 28,800 vibrations per hour (4 Hz) with 31 jewels. Equipped with the Chronergy escapement, blue Parachrom hairspring, and Paraflex shock absorbers, it delivers independent adjustment of the 24-hour GMT hand, instantaneous date change, stop-seconds precision, and a robust 70-hour power reserve. As a Superlative Chronometer (-2/+2 seconds per day after casing), it meets Rolex’s highest standards of performance.

Completed with the solid Everose gold Oyster bracelet featuring an Oysterlock safety clasp and Easylink 5 mm extension, the 126715CHNR embodies warmth, capability, and unmistakable Rolex GMT identity.
