Rolex GMT Master II

Overview

The Rolex GMT-Master II 16710 “Coke” is a highly recognisable travel watch with a strong connection to Rolex’s professional tool-watch tradition. Its red and black 24-hour bezel gives the model its enduring nickname, while the familiar 40mm Oyster case, practical GMT display and robust automatic movement make it equally suited to international travel and everyday wear.

Produced from 1989 until 2007, the reference 16710 occupies an important position in the development of the GMT-Master II. It retains the classic proportions and visual balance associated with earlier Rolex GMT models, while introducing the independent 24-hour hand that allows local time, home time and a third time zone to be read with the correct bezel setting. For collectors, it offers a compelling combination of period character, versatile dimensions and unmistakable Rolex design.

At £10,485, this watch sits within a category that continues to attract attention from enthusiasts seeking an authentic pre-owned Rolex with genuine horological purpose. The Coke bezel is especially distinctive: less monochromatic than the black bezel alternatives and more restrained than the blue and red “Pepsi” combination, it brings a discreet but confident colour contrast to the wrist.

Brand and reference history

Rolex introduced the GMT-Master in the 1950s to meet the needs of pilots and international travellers. The original design paired a conventional 12-hour display with a rotating 24-hour bezel, enabling the wearer to distinguish day from night in a second time zone. The GMT-Master II built on that foundation by allowing its additional 24-hour hand to be adjusted independently, making the watch more useful for modern travel.

Reference 16710 belongs to the long-running GMT-Master II generation that followed the earlier 16760. Its production period, from 1989 to 2007, places it firmly within Rolex’s transitional era, before the arrival of the larger and more technically modern ceramic-bezel generation. During its lifespan, the reference was available with different bezel colour combinations and bracelet configurations, but the red and black version remains one of the most individual.

The 16710 is also representative of the design language that made Rolex watches so successful among professionals. The case is substantial without being oversized, the dial is highly legible, and the Oyster bracelet provides a secure, familiar foundation. It is a watch designed first for use, yet its proportions and finish have given it lasting appeal as a collectible luxury object.

Dial, hands and design detail

The black dial provides the ideal background for the GMT-Master II’s functional display. Large luminous hour markers are arranged for rapid reading, with applied surrounds adding definition and a crisp Rolex finish. The date aperture at three o’clock is paired with the brand’s Cyclops magnifier, a practical detail that improves legibility while also forming one of the watch’s most recognisable visual signatures.

Time is indicated by the central hour and minute hands, supported by a seconds hand and the additional 24-hour hand used for a second time zone. The GMT hand reaches towards the outer bezel scale, allowing the wearer to compare local time with another location. Depending on the wearer’s chosen setting, the rotating bezel can also be used to display a third time zone, extending the watch’s usefulness beyond its original aviation brief.

The red and black bezel is the defining feature of this particular configuration. The black section typically indicates night-time hours, while the red section marks daylight hours on the 24-hour scale. This is more than a colour treatment: it helps the wearer interpret the second time-zone display at a glance. The contrast also gives the watch a warmer, more vintage character than an entirely black bezel.

Small details contribute to the overall impression. The Mercedes-style hour hand, lollipop seconds hand and arrow-tipped GMT hand create a layered but orderly display. Nothing is decorative without purpose; each element has evolved from the practical requirements of reading time quickly and accurately. The result is a dial that remains easy to understand despite offering more information than a conventional three-hand watch.

Case, bracelet and wearability

The 40mm stainless steel Oyster case is one of the reference 16710’s most appealing characteristics. It has enough presence to feel like a professional sports watch, yet its dimensions remain balanced and wearable by modern standards. The combination of polished and brushed surfaces gives the case visual depth, with the Oyster architecture providing the robust profile expected of a Rolex tool watch.

Its bidirectional rotating bezel carries a graduated 24-hour scale and forms an important part of the watch’s operation. The bezel can be aligned with the GMT hand to show home time, or rotated to calculate an additional time zone. Its tactile action is central to the watch’s character, turning what might otherwise be a simple display into a genuinely interactive instrument.

The Oyster bracelet continues the theme of functional durability. Its three-link construction is immediately familiar, with polished outer elements and brushed central surfaces creating a balanced finish. The bracelet integrates closely with the case and tapers naturally towards the clasp, helping the watch sit securely without becoming visually heavy.

For buyers comparing this model with other classic Rolex sports references, the 16710 offers a particularly versatile middle ground. It has more complexity than a conventional date watch, but remains slimmer and more understated than many contemporary professional models. Its proportions can transition from casual clothing to business wear with ease, much like the more dress-oriented Rolex Datejust, while retaining a distinctly adventurous identity.

Movement and technical specification

Inside the reference 16710 is Rolex calibre 3185, an automatic mechanical movement developed for the GMT-Master II. Its architecture supports the independent adjustment of the local hour hand, allowing the wearer to change time zones without stopping the movement or disturbing the position of the GMT hand. This is the key technical distinction between the GMT-Master II and earlier GMT-Master designs.

The movement is self-winding through the wearer’s natural motion and is protected by the Oyster case. As with any mechanical watch, performance depends on its service history, present condition, usage and the environment in which it is worn. A pre-owned example should therefore be judged not only by its reference and appearance, but also by the quality of its maintenance and the condition of its movement.

• Brand: Rolex

• Reference: 16710
• Nickname: “Coke”
• Case material: Stainless steel

The calibre 3185 is valued for its sensible combination of functionality, serviceability and proven Rolex engineering. It does not have the visual novelty of a contemporary movement with an exhibition back, but this watch was designed as a sealed professional instrument. Its strength lies in dependable operation, efficient winding and the ability to keep the travel complication practical rather than ornamental.

Sizing and how it wears

At 40mm, the GMT-Master II 16710 remains an adaptable size for a wide range of wrists. The diameter gives the dial and bezel enough space to be immediately legible, while the relatively restrained case proportions prevent it from feeling cumbersome. Its lug-to-lug presence is helped by the rounded Oyster case, which allows the watch to follow the wrist rather than sitting rigidly above it.

The bracelet contributes significantly to comfort. Its articulated links allow the watch to move naturally with the wrist, and the Oyster clasp keeps the overall profile secure. The result is a sports watch that can be worn throughout a full day without the sense of bulk associated with some larger modern travel watches. It is equally at home with a shirt cuff, knitwear or casual clothing.

The black dial and bezel give the watch a versatile foundation, while the red accents create enough personality to prevent it from appearing anonymous. That balance is one reason the 16710 works so well as a daily Rolex. It communicates technical purpose and enthusiast knowledge without demanding attention in the way a much brighter or larger watch might.

As with any pre-owned watch, the best fit will depend on wrist circumference, bracelet adjustment and personal preference. The 40mm case is generally considered an enduringly wearable size, but prospective buyers should consider how they prefer a watch to sit and whether they favour a snug or more relaxed bracelet fit.

Collectability and market value

The Rolex GMT-Master II 16710 “Coke” has a strong position among collectors because it combines a discontinued bezel configuration with the classic dimensions of the earlier GMT-Master II family. Its production run was substantial, but demand has remained high for well-preserved examples with attractive bezels, clean cases, correct components and convincing evidence of responsible ownership.

Its appeal is also rooted in its position between generations. The reference has the practical independent GMT hand associated with the GMT-Master II, yet it retains the slimmer, more traditional profile that many enthusiasts prefer over later oversized designs. It therefore appeals both to buyers seeking a functional travel watch and to collectors interested in the evolution of Rolex’s professional range.

Market value varies according to condition, originality, bracelet configuration, service history, dial and bezel condition, and the presence of supporting accessories. Red and black bezels can show age-related fading or surface marks, and these details may influence desirability differently depending on whether a buyer prefers a crisp original appearance or visible period character.

At £10,485, this example offers an opportunity to acquire a distinctive discontinued Rolex within the wider field of gmt & travel watches. The right purchase should be considered over the long term: a well-chosen 16710 can provide daily enjoyment, genuine travel functionality and an enduring connection to one of Rolex’s most important professional watch designs.

Authenticity, condition and servicing

Authenticity is central when buying any sought-after pre-owned Rolex, particularly a reference with a long production history and multiple period variations. A careful assessment should consider the watch as a complete system: case, bezel, dial, hands, movement, bracelet, clasp and markings should be evaluated together. Correct fit, finishing and consistency between components are all important indicators.

Condition should be understood in practical as well as cosmetic terms. Surface marks from careful wear may be expected on a pre-owned sports watch, while the quality of previous polishing, the definition of the case edges and the condition of the bezel are more significant when assessing overall character. The dial and hands should also be examined for consistency, legibility and appropriate ageing.

Mechanical condition is equally important. The movement should be assessed for winding efficiency, timekeeping, date change, GMT-hand operation and the smooth operation of the bezel. Water resistance should never be assumed solely from the model’s original specification; it should be tested by a qualified professional before the watch is exposed to water, especially if the service history is unknown or dated.

Servicing a vintage or discontinued Rolex should be approached thoughtfully. Preventative maintenance can help protect the movement and preserve reliable operation, but originality is also a key consideration for collectors. A service strategy should therefore balance functional requirements with the preservation of period-correct components and the watch’s existing character.
