Rolex GMT Master II

Overview

The Rolex GMT-Master II 126710BLRO is one of the defining modern travel watches. Recognised by collectors as the “Pepsi” GMT-Master II, its red and blue Cerachrom bezel combines immediate visual identity with a practical second-time-zone function. This example brings together Rolex’s robust Oystersteel construction, a 40mm case, a highly legible black dial and the brand’s dependable automatic calibre 3285.

Designed for frequent travellers but equally compelling as an everyday luxury watch, the 126710BLRO balances technical capability with unmistakable Rolex styling. Its rotating 24-hour bezel allows the wearer to read a further time zone, while the independently adjustable local-hour hand makes changing time zones straightforward. The result is a watch with genuine utility, strong wrist presence and enduring appeal across formal, business and casual settings.

At £17,950.00, this Rolex GMT-Master II sits within one of the most sought-after areas of the contemporary Rolex market. The combination of the iconic colourway, Oystersteel case and Jubilee bracelet gives the reference a particularly recognisable specification. For buyers seeking a modern Rolex with a clear horological purpose, it is an especially persuasive choice within our selection of gmt & travel watches.

Brand and reference history

Rolex developed the original GMT-Master in the 1950s in response to the needs of professional pilots and international travellers. Its defining innovation was the ability to read a second time zone through a 24-hour scale, a feature that transformed the watch from a conventional timekeeper into a practical instrument for global travel. The model’s close association with aviation and Pan American Airways helped establish the GMT-Master as one of the most recognisable sports watches ever made.

The GMT-Master II introduced a further refinement by allowing the local-hour hand to be adjusted independently of the 24-hour hand. This made it possible to set local time without losing track of home time or disturbing the minutes and seconds. Reference 126710BLRO represents the modern evolution of that concept, pairing Rolex’s current-generation movement technology with the traditional GMT layout and the famous red-and-blue bezel.

The “BLRO” designation refers to the bezel colours: blue and red. Rolex’s use of a two-colour Cerachrom insert gives the watch its familiar “Pepsi” nickname, while also providing the durability expected of a contemporary luxury sports watch. Within the wider range of Rolex watches, the 126710BLRO is notable for retaining the classic proportions and visual language of the GMT-Master while benefiting from modern materials and engineering.

Dial, hands and design detail

The black dial provides a strong contrast for the applied hour markers and white-gold surrounds. Large luminous markers at the cardinal points and baton indices support rapid reading in changing conditions, while the date aperture at three o’clock is paired with Rolex’s familiar Cyclops lens in the crystal. The dial is deliberately restrained, allowing the red GMT hand and vivid bezel to provide the principal flashes of colour.

The hour and minute hands are broad and highly legible, with luminous material applied to support visibility in low light. A distinct 24-hour hand points towards the bezel scale, enabling the wearer to distinguish home time from local time. The red tip of the GMT hand echoes the red half of the bezel and adds a precise visual accent without compromising the dial’s clarity.

The bidirectional bezel is fitted with a two-colour Cerachrom insert in blue and red ceramic. The engraved numerals and graduations are filled with platinum using a physical vapour deposition process, creating crisp definition and helping the markings remain clear over time. Cerachrom is highly resistant to scratching and offers strong resistance to ultraviolet exposure, helping the bezel preserve its colour and gloss through regular use.

Case, bracelet and wearability

The 40mm Oyster case is manufactured from Rolex Oystersteel, a corrosion-resistant alloy selected for its strength, durability and ability to retain an attractive finish. Its combination of polished and satin-brushed surfaces gives the case visual depth, while the familiar Oyster architecture provides a purposeful foundation for the watch’s travelling function. The screw-down crown and case back support the model’s water-resistant construction.

Reference 126710BLRO is paired with Rolex’s Jubilee bracelet, a five-link design with a more fluid, dress-oriented character than the three-link Oyster bracelet. Its articulated links allow the bracelet to conform comfortably around the wrist, while the Oysterclasp provides a secure closure. The bracelet’s mix of polished and brushed surfaces complements the case and gives the watch an adaptable presence that works particularly well with tailoring.

The overall design is practical without appearing utilitarian. The case has enough substance to feel reassuring, yet the 40mm diameter remains versatile across a wide range of wrist sizes. The bezel is visually prominent, but the black dial and restrained steel construction keep the watch balanced rather than excessive. It is equally at home with a suit, knitwear or relaxed weekend clothing.

Movement and technical specification

Powering the Rolex GMT-Master II 126710BLRO is Rolex calibre 3285, a self-winding mechanical movement developed for the current generation of GMT-Master II watches. It provides the central hours, minutes and seconds, an independently adjustable local-hour hand, a 24-hour display and a date indication. The movement is designed to deliver the precision, reliability and autonomy expected from a modern Rolex sports watch.

Calibre 3285 incorporates Rolex’s Chronergy escapement, which combines efficiency with resistance to magnetic interference. Its architecture also includes a blue Parachrom hairspring, selected for stability against temperature variation and shocks. The movement offers approximately 70 hours of power reserve, allowing the watch to continue running through a weekend when fully wound and not worn.

The GMT function is particularly intuitive. The red 24-hour hand remains associated with the reference time, while the conventional hour hand can be moved independently to show local time. The bidirectional bezel can then be adjusted to read a third time zone when required. This flexibility is one of the reasons the GMT-Master II remains more than a style icon: it is a genuinely useful mechanical travel instrument.

As with every mechanical watch, performance can be affected by wear patterns, position, magnetism and service history. The technical specification should therefore be considered alongside the individual watch’s condition and documentation. Our team can discuss the details supplied with this particular example as part of the buying process.

Sizing and how it wears

With its 40mm case diameter, the GMT-Master II 126710BLRO offers a versatile fit. The measurement gives the watch a confident presence without the oversized proportions found on some modern sports watches. Its relatively compact diameter and curved lugs help it sit neatly on the wrist, while the Jubilee bracelet adds flexibility and a smooth, comfortable feel during extended wear.

The watch is well suited to medium and larger wrists, although its balanced proportions allow it to work successfully on smaller wrists too. The red-and-blue bezel naturally draws attention, but the steel case and black dial prevent the overall effect from becoming visually heavy. The Jubilee bracelet also gives the watch a slightly more refined character than an equivalent model on an Oyster bracelet.

For travel, the layout is easy to understand at a glance. The red GMT hand indicates reference time against the 24-hour scale, while the local-hour hand can be set independently after arrival. The date remains linked to the local-hour hand, making the watch practical for crossing time zones. In daily use, this combination of comfort and clarity is a major part of the model’s appeal.

Collectability and market value

The Rolex GMT-Master II 126710BLRO occupies a particularly strong position among contemporary collectible sports watches. Its desirability is driven by several factors: the long history of the GMT-Master line, the instantly recognisable Pepsi colourway, the practical GMT complication, the modern calibre 3285 and the enduring reputation of Rolex. Few current travel watches offer the same combination of heritage, visual recognition and everyday usability.

The Jubilee bracelet is also significant to the character of this reference. It gives the watch a distinctive appearance and separates it from GMT-Master II configurations fitted with an Oyster bracelet. For many collectors, the combination of Oystersteel, Jubilee bracelet and red-and-blue Cerachrom bezel represents one of the most complete expressions of the modern GMT-Master II design.

Market value depends on variables including condition, completeness, age, service history, provenance and the presence of original accessories. Published asking prices can fluctuate, and no future value is guaranteed. Nevertheless, the 126710BLRO has demonstrated consistent demand because it appeals both to established collectors and to buyers looking for a single, highly capable luxury sports watch.

Authenticity, condition and servicing

Authenticity is central when buying a high-value pre-owned Rolex. The watch should be assessed as a complete object, including its case, bezel, dial, hands, bracelet, clasp and movement, with attention paid to consistency between the components and the stated reference. Any accompanying documents or accessories should also be considered as part of the individual watch’s overall presentation, rather than assumed from the model name alone.

Condition is equally important. A professional assessment considers the sharpness of the case lines, the quality of the bracelet, the bezel surface, the crystal, the dial and the operation of the crown and clasp. Minor signs of careful wear may be consistent with a pre-owned watch, while polishing, replacement parts or previous servicing can affect both appearance and collector appeal. We will provide the relevant details for this example rather than making assumptions that have not been verified.

Mechanical servicing should be carried out by suitably qualified specialists using appropriate equipment and genuine or correctly specified components. Service intervals vary according to use, environment and observed performance, so a fixed timetable should not replace an inspection. If you are considering this watch as a daily wearer, we can help explain the available information about its condition and servicing before purchase.
