Heading into this year’s Watches and Wonders show, rumors swirled that Rolex was going to unveil a GMT-Master II with a red-and-black bezel. Well, it wasn’t the Crown that released a new “Coke” — as the colorway is commonly referred to — but Rolex’s sister brand.
Tudor once again stole the show at the watch world’s biggest event of the year, this time by unexpectedly releasing a Coke GMT of its own. But it didn’t just slap a black-and-red bezel on the existing Black Bay GMT and call it a day. Oh no. Instead, the brand launched an entirely new model. Meet the Black Bay 58 GMT.

Tudor Black Bay Fifty-Eight GMT
This is the watch that many enthusiasts — present company included — have been clamoring for for years ever since Tudor launched the initial Black Bay GMT “Pepsi” back in 2018. Now, I can happily say that the Tudor Black Bay 58 GMT is real … and it’s spectacular. Here’s everything you need to know about it.
The Black Bay 58 GMT is compact. And thin!

The biggest complaints about the original Black Bay GMT was it was too large for many wrists, clocking in at 41mm across, 50mm lug-to-lug and a slab side that accentuated its 15mm thickness. When the brand followed that watch up with the 39mm Black Bay Pro a few years later, many were disappointed that the watch still was a chunky boi at nearly 15mm thick itself.
Perhaps feeling the heat due to increased competition from the likes of last year’s Spirit Zulu Time 39 from Longines, Tudor made sure the Black Bay 58 GMT’s measurements were pretty close to perfect. The watch measures 39mm across and 47.8mm long, but even more importantly, it’s just 12.8mm thick, allowing it to wear wonderfully on the wrist.
