Marc and Sons puts out some pretty nice dive watches, and some avaition models too. Back in January of 2018 I reviewed their 500M Diver. That was a fantastic timepiece. Well made, and offered at a good price. It’s been awhile since I checked out what Marc and Sons has been doing. Turns out they have been putting out some cool new stuff, including this Bronze GMT. Right away I liked the look of this thing and had to check it out.

The Dial

Marc and Sons uses a sandwich dial where the lumed hour markers show through cutouts in the face of the dial. The face is dark black with a glossy finish. To match the case, the hour, minute, and seconds hands are finished in a polished bronze look. The GMT hand is done is a vibrant red. All those hands are mounted to the reliable Swiss made ETA 2893-2 Elabore automatic movement. Surrounding all of this is a nicely done 60 click bi-directional “Pepsi” bezel using an aluminum insert. The bezel has a very solid feel to it with no play at all.

The Case

The case on this Marc and Sons GMT is made of CuSn8 bronze and uses a double anti-reflective sapphire crystal. Water resistance is an impressive 500 meters. The watch has a screw-down crown. Since the case is made from bronze it will react with oxygen, which will develop patina over time. Some may react more then other which gives each watch its own character. Speaking of character, the case back on this watch is really cool. The case back has what looks like an image of a large fish eating a smaller fish or who knows, maybe the little fish is chocking the big fish. Who will win? Measuring in at 41mm this case size will appeal to a large market since it’s in the just right size. Well at least for me it is.

The Strap

The strap is made from a soft brown leather. The lug is 22.0 mm wide and tapers down to 18.0 mm. The pin buckle clasp is also done in bronze. The brown leather strap and bronze buckle pair very well together and to me really dresses up the look of this watch.

The Lume

Marc and Sons uses Superluminova BGW9 lume on all indexes, hands, as well as the bezel. The glow is a nice blue/green and since it’s Superluminova, the glow will last for a long time.

If you travel a lot you will appreciate a good GMT watch. Of course any smartphone can show you multiple time zones, but to me its nicer to just glance down at my watch. I don’t want to pull out my phone each time, or wear a computer on my wrist. I like a good old watch for that. If you are the same like me then go check out this Marc and Sons Bronze GMT. Prices start at $714 USD and that’s not bad for this kind of quality. You can check them out at
