Well, let me tell you somethin’ about this here watch, the Black Bay 58 GMT. This thing, it ain’t too big, ain’t too small. It’s like Goldilocks, just right. They call it 39mm. I don’t know what them millimeters is, but it fits just fine on my wrist. And my wrists are like a little bird’s legs, all skinny and such.

Now, they talk about this Black Bay 58 GMT thickness. This Black Bay 58 GMT, it’s a little thicker, you see. They say it’s 12.8 of them millimeters. The regular one, the one that just tells the time, is only 11.9. So, this one’s got a little more meat on its bones, ya know? But it ain’t bulky, don’t get me wrong.
This watch, it got some pretty colors on the edge, the bezel they call it. Warm colors, like them old airplanes. The good old days when folks used to travel in style. Not like today, all crammed in like sardines in a can.
- This Black Bay 58 GMT, it’s 39mm wide.
- It’s 12.8mm thick, that’s what they say.
- The whole thing, from one end to the other, is 47.8mm.
Now, this other fella, the regular Black Bay, not the GMT one. It’s nearly the same size, just a little thinner. 0.9mm thinner, if you’re countin’. They shaved off a little here, a little there. Like whittlin’ a stick, you know?
They say they took off another 0.4mm somewhere. Made the whole thing 12.8mm thick. The big ones, the real hefty ones, those are 14.6mm. This here Black Bay 58 GMT, it’s closer to them fancy Rolex watches. You know, the ones the rich folks wear. This watch is still tough, though. You can take it swimmin’, 200 meters down! That’s deeper than I can even imagine. Deeper than the well out back, that’s for sure.
That Rolex, now there’s a name everyone knows. They make them good watches, I hear. Strong, good-lookin’, and not too thick. Just right, like this Black Bay 58 GMT. They say 40mm wide and about 12mm thick is the sweet spot. Sounds about right to me. Not too big, not too small, just like a good bowl of porridge.

The Black Bay 58 GMT thickness is just right for my old wrist. It feels good, you know? Not too heavy, not too light. Like a good quilt, keeps you warm but doesn’t weigh you down. And it looks good too, with them warm colors. Makes me think of them old travel posters, with the airplanes and all.
I reckon this Black Bay 58 GMT is a good watch. It tells the time, and it tells you the time in another place too, that’s what that GMT is all about, I suppose. I don’t travel much these days. My old bones ain’t what they used to be. But if I did, this here watch would be just the ticket.
They say it’s a “Master Chronometer.” Sounds fancy, don’t it? I don’t know what all that means, but it sounds important. Like when the preacher talks about them scriptures. Sounds important, even if you don’t understand all the words. This watch is probably like that. Full of fancy stuff that makes it tick real good.
So, if you’re lookin’ for a good watch, and you don’t want somethin’ too big and bulky, this Black Bay 58 GMT might be just what you need. It ain’t too thick, it ain’t too thin. The thickness of Black Bay 58 GMT is perfect. It’s just right. Like a good pair of shoes, you know? You want ’em to fit just right, or you’ll be sorry.
This watch, it’s like that. It fits just right. And it’ll probably last longer than me, too! That’s sayin’ somethin’. I’ve been around a long time, seen a lot of things. Seen a lot of watches come and go, too. But this one, this Black Bay 58 GMT, it feels different. It feels like it’s built to last. Like a good oak tree, strong and sturdy.

The Black Bay 58 GMT thickness, it’s just one part of it, but it’s an important part. It’s like the foundation of a house. You gotta have a good foundation, or the whole thing will fall apart. This watch, it’s got a good foundation. A good thickness. It’s gonna last. It is really a good choice to buy a watch with such good Black Bay 58 GMT thickness.
