Tudor Black Bay GMT

Overview

We are pleased to offer this Tudor Black Bay GMT S&G, reference 79833MN, presented in Tudor’s distinctive “Rootbeer” colour combination. Introduced to the range in 2023, this model brings the practical functionality of a true GMT watch together with the warm contrast of yellow gold details, a black dial and a brown leather strap. It is an especially versatile interpretation of the Black Bay family, balancing travel-watch capability with Tudor’s unmistakable vintage-inspired design language.

Priced at £2,995, this watch is supplied new as a full set and benefits from Tudor’s five-year warranty. Its 41mm stainless steel case houses the automatic Calibre MT5652, a COSC-certified chronometer movement with approximately 70 hours of power reserve. A fourth GMT hand tracks a second time zone, while the date display at 3 o’clock adds everyday practicality. The result is a capable, highly legible travel watch with considerable presence on the wrist.

Brand and reference history

Tudor has built its modern reputation by combining robust Swiss watchmaking with the design codes that made its historic tool watches so recognisable. The Black Bay collection is central to that success. It draws on Tudor’s dive-watch heritage, particularly the brand’s distinctive crown guards, domed crystals and snowflake hands, while presenting those elements in contemporary cases and mechanically sophisticated formats.

The Black Bay GMT S&G, reference 79833MN, extends that design story into the world of international travel. The “S&G” designation refers to the combination of steel and gold, while the “Rootbeer” description reflects the brown and black bezel palette traditionally associated with certain vintage travel watches. For buyers exploring Tudor watches, this reference is notable because it delivers a GMT complication without losing the character and visual familiarity of the Black Bay line.

Introduced in 2023, the model joined an established GMT family with a more luxurious and expressive finish. Rather than presenting as a purely utilitarian instrument, it uses gold accents and a brown leather strap to create a warmer, more refined interpretation. It remains unmistakably Tudor, but its colour scheme gives it a distinct identity within the broader Black Bay collection.

Dial, hands and design detail

The matt black dial provides a strong, low-reflection background for the applied hour markers and Tudor’s signature snowflake hour hand. The contrast is excellent, helping the principal time display remain immediately readable in changing conditions. Luminous material is applied to the hands and hour markers, allowing the display to remain visible after dark and reinforcing the watch’s practical, instrument-like character.

A dedicated GMT hand provides the second-time-zone indication. Its design is visually distinct from the regular hour and minute hands, making it straightforward to identify at a glance. The date aperture at 3 o’clock sits naturally within the dial layout and adds useful functionality without making the display feel crowded. This is an important part of the watch’s appeal: the additional information is clearly presented rather than treated as a decorative complication.

Above the dial, the domed sapphire crystal offers excellent scratch resistance and contributes to the softly curved profile associated with the Black Bay family. The crystal’s shape adds a subtle vintage reference, while the modern material and luminous treatment ensure that the watch remains suited to contemporary daily use. Together, the matte surface, sapphire crystal and snowflake hands create a design that is both recognisable and highly functional.

Case, bracelet and wearability

The 41mm case is made from stainless steel and provides a substantial but versatile platform for the GMT movement. Gold detailing adds warmth to the overall appearance, creating the two-tone character that defines the S&G model. The combination is particularly effective with the black dial and brown leather strap: the darker elements keep the watch grounded, while the gold brings a more considered, dressier finish.

The bi-directional bezel is one of the watch’s most distinctive features. Its black and brown colour scheme is designed to support the reading of a second time zone and gives the watch its “Rootbeer” nickname. The bezel can be used in conjunction with the GMT hand to make a quick adjustment when travelling, while the fixed local-time display continues to show the time at home or in the wearer’s principal location.

This example is fitted to a brown leather strap with a stainless steel folding clasp and safety catch. Leather softens the visual impact of the 41mm case and makes the watch a natural choice for travel, office wear and less formal weekend clothing. The folding clasp provides a secure closure and avoids the more casual feel that can sometimes accompany a traditional pin buckle. As a complete design, it offers a useful middle ground between rugged sports watch and refined daily companion.

Movement and technical specification

Powering the watch is Tudor Calibre MT5652, an automatic GMT movement developed for reliable everyday performance. It is COSC-certified as a chronometer, reflecting the movement’s tested accuracy, and offers approximately 70 hours of power reserve. That extended reserve is particularly convenient for a watch worn in rotation, as it can remain running through much of a weekend when removed on Friday evening.

The movement provides the essential functions expected of a modern travel watch: hours, minutes, seconds, a date display and an independently useful GMT indication. The fourth hand allows the wearer to track a second time zone, making the watch practical for international travel, remote work and keeping in contact with family or colleagues overseas. The movement’s automatic winding system also means that regular wear helps maintain its power reserve.

Sizing and how it wears

At 41mm, the case sits in a contemporary size bracket that suits a broad range of wrists. It has enough diameter to give the dial and GMT bezel clear visual presence, yet the Black Bay design prevents it from appearing overly aggressive. The watch’s proportions are balanced by the dark dial and strap, which help to reduce the visual mass of the case when viewed from above.

The brown leather strap also plays an important role in comfort. Compared with a full metal bracelet, it provides a softer, more flexible feel and gives the watch a slightly less formal relationship with the wrist. The steel folding clasp and safety catch support secure everyday wear, while the leather’s colour complements the gold accents and the warm tones of the Rootbeer bezel.

In practical terms, this is a watch that can transition comfortably between airport lounges, business settings and relaxed travel. The GMT display is useful without being intrusive, and the date makes it suitable for daily use. Buyers who prefer a compact vintage profile may find the 41mm case more substantial, but those looking for a modern travel watch with strong wrist presence should find the proportions convincing.

Collectability and market value

The Black Bay GMT S&G occupies an interesting position within Tudor’s catalogue. GMT watches are inherently attractive to enthusiasts because they combine a clear complication with genuine practical purpose, while the S&G format gives this model an added layer of visual distinction. The brown and black bezel, gold accents and leather strap ensure that it is not simply another variation on the standard Black Bay GMT formula.

Its 2023 introduction also gives the reference contemporary relevance within the current Tudor range. The watch benefits from the broader recognition of the Black Bay family, yet reference 79833MN has its own colour and material identity. For someone who already appreciates the collection, it offers a way to explore the line’s travel-watch capability while choosing a more individual and luxurious presentation.

Market value should always be considered alongside condition, completeness, warranty status and current availability. This example is offered at £2,995 and is supplied new as a full set with Tudor’s five-year warranty. Those details make it a compelling proposition for a buyer seeking a current-production Tudor GMT with the reassurance of complete presentation and manufacturer-backed coverage.

It also makes an appealing alternative to more conventional black-and-steel travel watches. The colour palette has enough restraint for regular wear, but the gold and brown elements provide the character that many collectors look for when adding a further GMT to an existing collection. Within the broader Black Bay family, it is a particularly distinctive choice; those considering the Tudor Black Bay range may find this model’s complication and Rootbeer styling especially attractive.

Authenticity, condition and servicing

This Tudor Black Bay GMT S&G is supplied new as a full set. That presentation is significant for a modern luxury watch, as it provides the buyer with the appropriate accompanying materials and supports a complete ownership experience from the outset. The watch also benefits from Tudor’s five-year warranty, offering manufacturer-backed reassurance for the covered period.

As with any mechanical watch, long-term performance depends on sensible care and appropriate servicing. The sapphire crystal is highly resistant to everyday scratching, but the case, bezel, clasp and leather strap should still be protected from unnecessary knocks, moisture and harsh chemicals. The leather strap will naturally develop character with use and may eventually require replacement depending on wear, climate and the owner’s routine.

The automatic movement is designed for reliable daily operation, but servicing should be carried out by an appropriately qualified watchmaker or an authorised Tudor service centre when required. It is sensible to avoid operating the date mechanism during the movement’s date-change period and to ensure that the crown is fully secured before exposing the watch to water. These straightforward habits help preserve both performance and appearance.

We do not make claims about provenance beyond the information provided for this particular watch. The important details available here are clear: it is reference 79833MN, it is offered new as a full set, and it carries Tudor’s five-year warranty. Buyers can therefore assess the watch on a transparent basis, with its specification, presentation and warranty status set out directly.
