Tudor Black Bay GMT

Overview

The Tudor Black Bay GMT S&G, reference 79833MN, brings Tudor’s travel-watch expertise together with the warm contrast of steel and yellow gold. Presented in the distinctive “Root Beer” colourway, it pairs a matt black dial with a two-tone case and a black-and-brown 24-hour bezel. The result is a practical GMT watch with unmistakable character, equally suited to frequent travel and everyday wear.

Introduced to the Tudor range in 2023, this Black Bay GMT S&G is offered new as a full set and benefits from Tudor’s five-year warranty. Its 41mm stainless-steel case houses the chronometer-certified Calibre MT5652, while the independent GMT hand allows a second time zone to be read at a glance. A date display at 3 o’clock, luminous detailing and a secure folding clasp complete a highly capable package.

For buyers comparing Tudor watches, this reference occupies an appealing position: it offers the functionality of a serious traveller’s watch while retaining the robustness and vintage-inspired design language associated with the Black Bay family. At £2,995, it represents an attractive opportunity to acquire a current Tudor GMT in a particularly distinctive two-tone configuration.

Brand and reference history

Tudor was established by Hans Wilsdorf, the founder of Rolex, with the aim of creating watches that combined dependable Swiss engineering with a more accessible position in the market. Over time, the brand developed its own identity through strong tool-watch designs, robust movements and recognisable details such as the snowflake hand. The Black Bay collection is central to that identity, bringing historical dive-watch influences into contemporary cases and movements.

The Black Bay GMT extends that design language into the world of international travel. Rather than presenting a purely modern instrument, Tudor uses familiar Black Bay cues—including the prominent crown, snowflake hour hand and domed crystal—to create a watch with a clear family resemblance. Reference 79833MN adds yellow-gold elements to the steel construction, while its “Root Beer” bezel introduces a richer, more autumnal palette than the standard black-and-red GMT.

The “S&G” designation refers to Tudor’s steel and gold construction. Here, the combination is not simply decorative: the polished gold-toned bezel and crown details provide contrast against the brushed and polished steel case, creating a more refined interpretation of the established Black Bay GMT. Since its introduction in 2023, the model has appealed to enthusiasts seeking a travel watch with a stronger visual presence than an all-steel alternative.

Dial, hands and design detail

The matt black dial provides a calm, highly legible foundation for the watch’s travel-focused display. Applied hour markers stand out clearly against the dark surface, while the snowflake hour hand gives the watch one of Tudor’s most recognisable signatures. The broad hand shape is practical as well as distinctive, making the local hour easy to identify without compromising the reading of the other indications.

A dedicated GMT hand extends towards the outer scale to show a second time zone, and its contrasting colour helps separate it from the conventional hour and minute display. The 24-hour bezel can be rotated in both directions, allowing the wearer to align the scale with the GMT hand and track a further time zone. This makes the watch useful not only when crossing borders, but also for following home time, market hours or communications with colleagues overseas.

The date aperture at 3 o’clock adds everyday practicality without overwhelming the dial. Luminous material is applied to the hands and hour markers, supporting clear reading in subdued conditions. The domed sapphire crystal contributes to the Black Bay’s slightly vintage character while offering strong resistance to everyday scratching. Together, the dial, hands and bezel balance nostalgia with the clarity expected from a modern mechanical travel watch.

Case, bracelet and wearability

The case measures 41mm across and is made from stainless steel, with selected yellow-gold elements creating the S&G finish. This is a substantial but versatile diameter for a contemporary sports watch. Its rounded Black Bay profile, defined lugs and prominent crown give it a confident wrist presence, while the combination of brushed and polished surfaces keeps the case visually engaging from different angles.

The bi-directional bezel is one of the defining features of the reference. Its two-tone black-and-brown colour scheme gives the watch its “Root Beer” nickname and provides the visual framework for reading the second time zone. The gold bezel construction adds warmth and a more luxurious note, contrasting naturally with the steel case and matt black dial.

This example is fitted to a brown leather strap with a steel folding clasp and safety catch. The brown leather works particularly well with the bezel’s warmer tones, giving the watch a cohesive appearance rather than the sharper contrast associated with a black strap. The folding clasp helps keep the watch securely positioned on the wrist, while the safety catch adds reassurance during daily wear.

As a complete new set, the watch is suitable for a buyer looking for a current Tudor with immediate presentation appeal. The leather strap also makes it easy to dress the Black Bay GMT S&G up or down: it can accompany business clothing, travel attire and relaxed weekend wear without appearing out of place.

Movement and technical specification

Powering the watch is Tudor Calibre MT5652, an automatic GMT movement developed for the Black Bay GMT. It provides a useful 70-hour power reserve, meaning the watch can be removed for a weekend and still have a strong chance of continuing to run when picked up again. That extended reserve is particularly convenient for owners who rotate several watches.

The movement is chronometer certified, reflecting testing against recognised standards for precision. It also provides the central functions expected from a modern GMT: local time, a second time-zone indication and a date display. The independent travel-time functionality allows the wearer to adjust the local hour without losing the reference time, making the watch practical when moving between time zones.

Sizing and how it wears

At 41mm, the Black Bay GMT S&G is sized to make the most of its travel-watch purpose without becoming excessively large. The diameter provides sufficient space for a clear dial and readable 24-hour scale, while the rounded case profile helps it sit naturally on the wrist. Its presence is noticeable, but the design remains balanced rather than oversized.

The leather strap contributes to the watch’s comfort and visual flexibility. Compared with a full metal bracelet, leather gives the watch a softer, lighter feel and allows the case to remain the focus. The folding clasp and safety catch offer a secure connection, and the strap’s brown tone complements the gold and brown details throughout the design.

Wrist proportions remain important with any 41mm watch, particularly one with a substantial crown and rotating bezel. On a medium or larger wrist, the Black Bay GMT’s broad dial and strong case lines create a confident fit. On a smaller wrist, it will wear as a purposeful sports watch, with the leather strap helping to soften the overall impression.

The watch is also easy to style across different settings. The gold accents add sophistication for evenings or business travel, while the black dial, luminous display and robust case retain the practical character expected of a Black Bay. For shoppers browsing gmt & travel watches, it offers a particularly versatile balance between utility and luxury.

Collectability and market value

The Black Bay GMT has established a clear place within Tudor’s modern catalogue because it combines one of the brand’s most recognisable collections with a complication that has enduring practical value. A mechanical GMT is useful, easy to understand and strongly associated with international travel, giving the model relevance beyond purely stylistic appeal. The S&G version adds another layer of interest through its two-tone construction and Root Beer colour scheme.

Reference 79833MN is especially appealing to buyers who want the Black Bay GMT’s functionality without choosing the more familiar all-steel look. The black-and-brown bezel has a warmer, more individual character, while the gold details introduce a dressier quality. At the same time, the 41mm case, snowflake hands and domed sapphire crystal keep the watch firmly connected to the Black Bay design family.

Market value should always be considered alongside condition, completeness, warranty status and the exact specification of the watch. This example is supplied new as a full set and includes Tudor’s five-year warranty, factors that strengthen its appeal for a buyer who values clear documentation and manufacturer support. Its price of £2,995 positions it as a compelling way to obtain a current Tudor GMT with a distinctive two-tone execution.

Those researching the Tudor Black Bay GMT will find this reference particularly attractive if they want a watch that can serve as both a dependable travel instrument and a statement of personal taste. Its specification is broad enough for daily use, while its Root Beer styling gives it a stronger identity than many conventional GMT watches.

Authenticity, condition and servicing

This Tudor Black Bay GMT S&G is offered new as a full set. The supplied set and current presentation make it a strong choice for a buyer who wants to purchase with confidence and retain the watch’s complete ownership package. The reference is 79833MN, and the stated specification includes the brown leather strap, steel folding clasp and safety catch described above.

The watch also benefits from Tudor’s five-year warranty. This provides manufacturer-backed support for the applicable warranty period and is an important advantage when purchasing a modern mechanical watch. Buyers should always retain the warranty documentation and follow Tudor’s guidance for use, care and maintenance.

As with any mechanical timepiece, regular servicing will eventually be required, although the appropriate interval depends on use, performance and the manufacturer’s recommendations. Avoid exposing the watch to impacts, magnetic fields or conditions outside its intended specification, and arrange professional assessment if the watch develops an unusual gain, loss or operational issue. Servicing should be entrusted to an appropriately qualified watchmaker or Tudor service centre.

The sapphire crystal is highly resistant to everyday scratches, but it is not indestructible, and the polished and gold-toned surfaces should be treated with care. The leather strap will naturally develop character through wear and may require replacement over time, particularly if regularly exposed to moisture. Careful storage and gentle cleaning will help preserve the watch’s finish and presentation.
