The Tudor Black Bay GMT: A Modern Watch Worth Your Attention

Tudor today and Tudor from twenty years ago. If you removed the brand name from the dials, you’d be forgiven for thinking they came from two entirely different manufacturers. If you’re not deeply into watches, you might not know that Tudor was originally positioned as Rolex’s more affordable sibling. What might surprise you is how thoroughly that narrative has shifted with watches like this: The Tudor Black Bay GMT Ref. 79830RB.

Tudor released the Black Bay GMT in 2018, establishing its identity with the in-house MT5652 movement—a significant milestone that transformed the brand from “affordable Rolex” to a manufacture in its own right.

Look Closer

To some, you might say, it’s just another GMT watch. How many red and blue bezels are there? Quite a lot. But to that I say: look closer.

That burgundy and blue ceramic bezel isn’t trying to be a Rolex GMT-Master II. The hues are warmer, and the gilt accents throughout the dial give it a vintage character that modern Rolex has abandoned. The snowflake hands—a design Tudor has used since their 1950s dive watches—are immediately recognizable without being gimmicky.

The movement impressed me when I first handled one. The 70-hour power reserve means you can take it off Friday and put it back on Monday without it dying. The finishing, visible through the exhibition caseback, is genuinely beautiful—Geneva stripes and a signed rotor. For this price point, remarkable.

Why This Matters

At 41mm, this wears perfectly on most wrists. The lug-to-lug is sensible, the bracelet taper elegant. You could wear this with a suit or jeans, to a meeting or on a dive (200m rated).

The in-house movement is significant. While competitors were buying movements from ETA or Sellita, Tudor developed their own. That’s a statement of intent. The MT5652 is COSC-certified with a silicon hairspring for magnetic resistance. A proper manufacture caliber.

This watch represents modern watchmaking done right. No shortcuts, just a well-executed tool watch that happens to be beautiful.

This Example

This particular piece is in 95% condition—worn but cared for. Sharp case, satisfying bezel action, light desk marks. Complete with box and warranty card from 2021, capturing the moment when Tudor fully came into its own as a manufacture.

The price is $22,000—fair when a comparable Rolex GMT-Master II trades for more than double that, assuming you can even find one.
