Meet Tudor’s colorful Black Bay GMT

WORLDWIDE ARTISTRY. By adding a new GMT function, Tudor is introducing the Black Bay to the world of global travelers

Back at this year’s Baselworld fair, Tudor introduced the Black Bay line with a highly functional complication: A multiple time-zone function—also known as a GMT function—that establishes local time without losing sight of the time in two other time zones. What makes this watch even more special, other than the fact that it is sporting a distinctive burgundy and blue bezel, is that it is equipped with a new manufacture movement.

Physical Attractiveness
Like the other models in the famed Black Bay line, the new Black Bay GMT features a dial inspired by Tudor’s divers’ watches produced during the 1950s. Recognizable by its rotatable bezel, which derives its deep blue and burgundy matt color scheme from other models in the Black Bay line, the Black Bay GMT is also a nod to the early days of this complication.

Additional time zones are indicated by an aesthetic hallmark of Tudor – a signature red snowflake hand, as well as a bidirectional 24-hour rotatable bezel. Up front, its contrasting black dial means that it is legible in all conditions, including night-time, thanks to its luminescent hour markers.

Designed to withstand the elements, the Black Bay GMT model comes in a steel case measuring 41mm in diameter. Completed with a riveted metal bracelet—again, inspired by the Tudor watches produced in the 1950s and 1960s—the Black Bay GMT model also comes with other optional straps designs, including the “Terra di Siena” brown leather strap and folding clasp or black fabric strap with a burgundy band.

It’s also interesting to note that the twelve daylight hours are printed on the burgundy section of the Black Bay GMT’s bezel, while the night-time hours on the blue part. The characteristic angular hands is also pretty much well known to collectors as it appeared in the brand’s 1969 catalogue.

So, the Black Bay GMT is essentially a subtle blend of traditional aesthetics and contemporary watchmaking know-how. It brings together over 60 years of Tudor divers’ watches while also being resolutely anchored in the present. With the manufacturing techniques, reliability, robustness and the quality of its finish which are consistent with today’s more rigorous requirements, it goes without saying that new Black Bay GMT ticks all the right boxes in terms of sights and style.

Special Engine
Inside the case, we find the new Manufacture Calibre MT5652, which has has been developed by Tudor for this particular Black Bay GMT and demonstrates a new approach to development. Rather than adding ever more complicated modules, the integration of new functions is made possible by a flexible architecture.

Appearance wise, the Calibre MT5652 has a defining detail. Its structure has been designed to ensure robustness, longevity and reliability, as has its variable inertia balance, which is maintained by a sturdy traversing bridge with a two-point fixation. Thanks to these qualities, together with its non-magnetic silicon balance spring, it is certified as a chronometer by the Swiss Official Chronometer Testing Institute (COSC). On top of that, with a 70-hour power reserve, you can take off the watch on Friday evening and put it back on your wrist again on Monday morning without having to re-set and wind it. All in all, for their first introduction of a GMT function in a Black Bay line, Tudor has surely made all the right moves.
