Tudor Predictions 2025: Black Bay GMT Refresh

In 2018, Tudor debuted the Black Bay GMT — a 41mm travel watch that changed the game for sub-$5,000 GMTs. Its red-and-blue ‘Pepsi’ bezel nods to sibling brand Rolex, but Tudor’s vintage-inspired flair sets it apart: namely the faux-rivet bracelet and snowflake handset.

Tudor has been steadily upgrading its core Black Bay lineup with slimmer cases, reworked proportions, METAS-certified movements, and the now-standard T-Fit clasp. These changes have already made their way to the 41mm Black Bay diver (first with the Burgundy model, then the Monochrome) and partially to the Black Bay Chrono. Most recently, Tudor introduced the Black Bay 58 GMT — an all-new 39mm, gilt-accented GMT that wears completely differently from the 41mm original.

And that’s the key distinction.

The Black Bay 58 GMT is not a replacement for the Black Bay GMT. Just like the 39mm Black Bay 58 diver coexists with the original 41mm Black Bay diver, these are separate GMT models built for different wrists and preferences. Some collectors lean toward the smaller, vintage-leaning 58. Others want the larger, more substantial feel of the 41mm — especially in a rugged, travel-ready tool watch.

Which is exactly why we think a second-generation Black Bay GMT is coming.

The Case for an Updated Tudor Black Bay GMT

The original Black Bay GMT is still an excellent watch. But at 14.6mm thick, it’s due for a trim — especially now that the 58 GMT comes in at a much slimmer 12.8mm. We’ve already seen Tudor apply similar refinements to the 41mm Black Bay diver: a leaner case profile, a dial closer to the crystal, and updated bracelet options.

It would make perfect sense to do the same here.

We’d expect Tudor to keep the MT5652 movement but give it METAS certification, just like they did in the Pelagos GMT ‘Zulu Time’. The T-Fit clasp now feels like a given, and the crown tube design — already phased out on the Black Bay and 31/36/39/41 — could be next to go.

If Tudor brings over bracelet options from the Burgundy, we could see the five-link bracelet and integrated rubber strap make their way to the GMT. That would give buyers a more modern-feeling option than the rivet-style bracelet.

What About New Colors?

Hard to say. The opaline dial introduced in 2023 still feels fresh. Tudor doesn’t churn out new bezel colors often, but a bold option to mark a new generation isn’t out of the question.

And yes — maybe that means a Coke bezel.

Let’s not get carried away, but it’s worth noting that the original Black Bay GMT launched the same year as Rolex’s first ceramic steel Pepsi GMT. If Rolex releases a Coke GMT-Master II in 2025 (as many suspect), we could easily see Tudor doing the same with its new Black Bay GMT. Still, even if the bezel stays Pepsi, a slimmer case and METAS certification would be significant upgrades on their own.

Final Thoughts

Tudor has shown that it’s committed to the slow-and-steady, iterative approach of their sibling brand. The updates to the Black Bay Burgundy and Monochrome, Chrono, and other models show refinement rather than complete reinvention.

We exact the same from the Black Bay GMT. It deserves the same treatment. A second generation would let Tudor offer a full-size GMT for collectors who prefer 41mm watches — now with everything we expect from the modern Black Bay lineup.
