The Rolex GMT-Master II 126729VTNR is a 40 mm 18 kt white-gold travel watch with a green ceramic dial, a green-and-black Cerachrom bezel, and a crown on the left side of the case. Rolex’s US product page lists it at $54,700 USD; that regional list price can change. Its calibre 3285 keeps the GMT-Master II’s familiar independent local-hour setting rather than introducing a new movement.
What is new about the Rolex 126729VTNR?
The 126729VTNR combines an 18 kt white-gold Oyster case and bracelet with a green ceramic dial and green-and-black Cerachrom bezel insert. Its crown and crown guards are on the left, and the date aperture and Cyclops lens are at 9 o’clock. Rolex identifies the ceramic dial as a first for the brand’s watches.
Rolex says the dial’s green Cerachrom component is made by fitting a ceramic disc to a brass plate and is the same shade as the bezel’s green portion. The green dial and bezel distinguish this reference visually, while the movement and GMT operating principle remain part of the established GMT-Master II platform.
Why the left-handed layout matters
“Lefty” or “destro” describes the case layout: the winding crown and crown guards are on the left, and the date and Cyclops lens are at 9 o’clock. It is a configuration feature, not a guarantee of comfort for every left-handed wearer.

Rolex’s history distinguishes the left-crown configuration from the ceramic-dial milestone. The green ceramic dial arrived in 2025; the left-crown layout is an earlier GMT-Master II development. The reference number 126729VTNR is the clearest formal name for this model.
Case, materials, and wearing proposition
Rolex specifies a 40 mm Oyster case in 18 kt white gold, with a monobloc middle case, screw-down case back, and screw-down winding crown. The crown uses Rolex’s Triplock system. Rolex lists water resistance at 100 metres (330 feet).
The bracelet is a three-piece solid-link Oyster bracelet in 18 kt white gold. It has an Oysterlock folding safety clasp and an Easylink 5 mm comfort extension. The white-gold construction differentiates the watch from steel GMT-Master II references; the supplied research does not establish an official weight or thickness for this model.
The green ceramic dial and Cerachrom bezel
Rolex’s 2025 newsroom describes this as the brand’s first ceramic dial, introduced on an 18 ct white-gold GMT-Master II with the crown on the left and date at 9 o’clock. Rolex says the dial’s green component matches the lower green portion of the bezel insert. This first-dial claim should not be confused with the history of the left-crown layout.

Rolex’s history page says Cerachrom first appeared on a GMT-Master II in 2005, initially in black, and that two-colour versions followed in 2013.
How the GMT function works
The arrow-tipped 24-hour hand makes one revolution per day and indicates home or reference time against the bezel’s 24-hour graduations. For travel, the local hour hand moves independently in one-hour jumps without disturbing the minute and seconds hands.
- Set the 24-hour hand to home time or another chosen reference time.
- When entering a new time zone, move the local hour hand forward or backward in one-hour increments.
- Read the reference time from the 24-hour hand against the bezel.
- Rotate the bidirectional bezel when a different temporary 24-hour offset is useful.
Rolex lists centre hours, minutes and seconds, a 24-hour display, a second time zone, an instantaneous date, and stop-seconds among the watch’s functions.

Calibre 3285: familiar, capable, and not the headline
The 126729VTNR uses Rolex’s self-winding calibre 3285. Rolex lists an approximately 70-hour power reserve and precision of -2/+2 seconds per day after casing under its Superlative Chronometer standard. These are manufacturer specifications, not independent test results.

The movement is not described by Rolex as a new calibre created specifically for this reference. The watch’s distinction is its combination of the established GMT function with the white-gold case, left-side crown, and green ceramic dial.
Price, availability, and buying context
Rolex’s US product page lists the 126729VTNR at $54,700 USD. This is the displayed US list price, not a worldwide price, transaction value, or guarantee of availability; regional prices, taxes, and availability may differ, and the figure can change.
For purchase, authentication, or service, Rolex says official Rolex jewelers are authorized to sell and maintain its watches. Use Rolex’s authorized Rolex jeweler locator for that channel. The supplied research does not establish third-party seller authorization or a verified secondary-market value.
Ownership considerations
The available research establishes the watch’s self-winding movement and power reserve but does not establish that a winder is required or beneficial. A winder is therefore an optional convenience, not a necessity supported by the cited Rolex specifications. For sizing, opening, or maintenance, use an authorized Rolex jeweler.

Is the 126729VTNR a new-generation GMT-Master II?
It is not presented as a new movement generation: it uses calibre 3285 and the familiar GMT-Master II travel function. Its notable distinctions are the white-gold construction, left-crown/date-at-9 layout, and green ceramic dial.
Rolex’s 2025 newsroom identifies the ceramic dial as a first for the brand. The crown layout is a separate, earlier model milestone, so the two claims should not be conflated.
Verdict
The Rolex GMT-Master II 126729VTNR is a precious-metal version of the GMT-Master II with a distinct left-crown layout and green ceramic dial. Its travel function comes from calibre 3285: the 24-hour hand tracks a reference time while the local hour hand jumps independently for time-zone changes. The defining update is the materials and configuration, not a new movement.
FAQ
Is the Rolex GMT-Master II 126729VTNR Rolex’s first left-handed GMT?
No. The 126729VTNR has the crown on the left and date at 9 o’clock, but Rolex’s historical account identifies that layout as an earlier milestone. The brand identifies the 2025 green ceramic dial as its first ceramic dial.
How much does the Rolex 126729VTNR cost?
Rolex’s US product page consulted in 2026 lists it at $54,700 USD. This is a regional list price, not a global price or a statement about availability or resale value.
What movement is in the Rolex 126729VTNR?
It uses Rolex calibre 3285, a self-winding GMT movement. Rolex lists approximately 70 hours of power reserve and precision of -2/+2 seconds per day after casing.
How does the left-handed layout work?
The crown and crown guards are on the left side of the case, and the date aperture and Cyclops lens are at 9 o’clock. “Lefty” describes this layout; it does not guarantee a particular wearer’s comfort.
