Reference:126715CHNR

From BezelBase


GMT-Master → 126715CHNR

The 126715CHNR is the solid-Everose GMT-Master II Rootbeer. It launched at Baselworld 2018 in the same press event as the Rolesor 126711CHNR and the steel Pepsi 126710BLRO, and it shares both the two-colour brown-and-black Cerachrom bezel and caliber 3285 with its Rolesor twin. What separates it out is the case and bracelet. Both are solid 18k Everose gold, which puts the 126715CHNR at the top of the current GMT-Master II lineup and makes it the heaviest modern GMT-Master II on the wrist.

The reference also carries the only catalogued dial variant inside the current Rootbeer pair. In 2025, Rolex introduced the 126715CHNR-0002 Tiger Iron, a hardstone-dial version cut from a natural stone composite of tiger’s eye, red jasper, and black hematite mined in Western Australia. The standard black-dial configuration continues as the 126715CHNR-0001, which keeps the 2018 launch specification unchanged.

Where it sits in the line

The 126715CHNR is the solid-gold half of the 2018 Rootbeer pair, positioned above the Rolesor 126711CHNR. The Rolesor version provides the everyday access point to the colourway. The solid Everose version carries the same bezel and dial identity at a higher price and a much heavier wrist weight. aBlogtoWatch’s launch coverage catalogues the split at US$14,050 for the Rolesor and US$36,750 for the solid Everose.

The solid-gold Rootbeer lineage reaches back to the yellow-gold 1675/8 and 16758, both 1970s solid-gold GMT-Masters with brown-and-gold aluminum Rootbeer inserts. Sotheby’s catalogue entry for the 126715CHNR explicitly frames the modern reference as a homage to those watches. The departures mirror the 126711CHNR: Everose replaces yellow gold, two-colour Cerachrom replaces aluminum, and the dial shifts from a brown sunburst to a gloss black (or, on the -0002, a hardstone cut).

Alongside it in the current lineup sit the 126711CHNR, the steel 126710BLRO Pepsi, the steel 126710BLNR Batman, the two-tone yellow-gold 126713GRNR from 2023, and the solid yellow-gold 126718GRNR. The 126715CHNR remains the only solid Everose reference in the current line.

Production outline

The reference launched at Baselworld 2018. Sotheby’s catalogued an early-production circa-2018 example in its 2020 watch sale, anchoring the launch year in the auction record. Production has run continuously since.

The 2025 Tiger Iron dial was introduced at Watches & Wonders 2025 as part number 126715CHNR-0002, alongside the green-ceramic 126729VTNR that replaced the steel Pepsi 126710BLRO in the lineup. SJX, Monochrome, aBlogtoWatch, and Revolution all covered the Tiger Iron launch. The standard black-dial 126715CHNR-0001 continues in parallel. SJX’s coverage notes the retail premium the stone-dial version carries over the standard reference.

The Meteorite dial sometimes associated with the Rolex stone-dial programme does not appear on the 126715CHNR in the current documented lineup. The image registry for this reference catalogues only the standard black and the Tiger Iron configurations, and the Tiger Iron is the only official dial variant released alongside the reference during its production run.

Movement notes

Caliber 3285 powers the reference from launch. The same movement runs in the Rolesor 126711CHNR and across the 2018-onward GMT-Master II generation. Two changes define it against the earlier caliber 3186. The Chronergy escapement replaced the standard Swiss lever layout, and power reserve moved from 50 hours to 70. The Blue Parachrom hairspring carries over, and the 3285 sits inside the Superlative Chronometer specification with rate accuracy to -2/+2 seconds per day. The 2025 Tiger Iron variant carries the same caliber unchanged.

Dial map

The 126715CHNR is the only modern ceramic GMT-Master II reference with a catalogued dial variant, which gives it a real dial map rather than a single configuration.

Standard black dial (-0001)

Gloss black lacquer with Chromalight lume plots in Everose PVD-coated borders, Everose-rimmed baton and triangle indexes, and Everose hands including the GMT hand. This is the configuration released at Baselworld 2018 and the one Sotheby’s catalogued in its 2020 lot. Fratello’s Everose hands-on describes the dial in these terms.

Tiger Iron (-0002)

The 2025 Watches & Wonders variant uses a dial cut from tiger iron, a natural stone composite of tiger’s eye, red jasper, and black hematite mined in Western Australia. aBlogtoWatch, Monochrome, SJX, and Revolution all cover the launch in hands-on detail. The stone’s banded structure gives each dial a unique pattern, and the brown-gold tiger’s eye layers, red jasper veins, and black hematite bands read as a natural analogue to the Cerachrom bezel directly above. Case, bezel, movement, and bracelet carry over from the -0001 without change. The dial is the only difference between the two part numbers.

Tiger Iron sits inside Rolex’s broader programme of hardstone dials on Day-Date and other precious-metal references, but this is the first natural stone dial on a GMT-Master II. SJX frames the release as an exotic-dial halo inside the Everose Rootbeer line, with the black-dial -0001 continuing in parallel.

Case, bezel, crystal, and crown notes

The case is 40mm solid 18k Everose gold throughout, including the bracelet. Everose is Rolex’s patented platinum-fortified pink-gold alloy, introduced in 2005 to resist the colour fade of standard rose-gold alloys. The case shares the Oyster architecture, Triplock crown, and 100m water resistance of the rest of the ceramic-era GMT-Master II line. On the wrist, the reference is noticeably heavier than the Rolesor 126711CHNR, a point Fratello addresses in hands-on coverage.

The Cerachrom bezel is shared with the 126711CHNR. The brown-and-black insert is the first two-colour ceramic bezel produced on a GMT-Master II, cast as a single ceramic piece with the two colours produced by sintering chemistry rather than painting or lamination. The 24-hour numerals are moulded into the ceramic in Everose gold. The bezel ring itself is solid Everose, not Rolesor-combined. Revolution’s 2025 Tiger Iron coverage confirms the bezel is unchanged across the -0001 and -0002 variants.

Bracelets, end links, clasps, and packaging notes

The 126715CHNR ships on the solid 18k Everose Oyster bracelet with solid end links and an Oysterlock clasp carrying the Easylink 5mm comfort extension. The bracelet is structurally identical to the Rolesor Oyster on the 126711CHNR but executed entirely in Everose. Rolex’s current product page catalogues the same configuration across the -0001 and -0002 part numbers, and Monochrome’s Tiger Iron macro shots confirm the bracelet is carried over without change on the 2025 variant.

Special branches

Tiger Iron -0002

The 2025 hardstone dial is the reference’s only production branch. SJX and aBlogtoWatch both describe the stone-dial positioning as a premium halo above the black-dial -0001. The banded natural stone produces unique dials per watch, which is unusual inside the GMT-Master II family and more typical of Day-Date hardstone programmes elsewhere in the Rolex catalogue.

Standard black dial -0001

The launch-specification black-dial reference continues in parallel. Fratello documents the standard configuration through the production run. The watch has not received a movement or case change between 2018 and the 2025 dial split.

Historical market and auction record

Sotheby’s 2020 watch sale catalogued an early-production circa-2018 Everose 126715, described as a homage to the 1970s Rootbeer GMTs. That lot is the clean auction anchor for the launch year. Secondary-market data for the 126715CHNR is thinner than for the Rolesor sibling, matching the pattern for solid-gold variants of high-production Rolesor references. The 2025 Tiger Iron release has drawn editorial attention from Monochrome, Revolution, SJX, and aBlogtoWatch, but its own auction record has not yet formed. The solid-Everose Rootbeer reads as a halo piece inside the current GMT-Master II line rather than a high-volume secondary-market reference.
