That thin aqua stripe running down each edge is the whole trick here. Bamford London’s Bark & Jack strap takes the black-and-aqua palette from its Casio collaboration and moves it onto black nylon, so the color doesn’t stop where the case ends.
It’s a small swap for a watch that already wears Bamford blue on its bezel, but it’s the kind of small swap I’d notice every time I put it on.

A G-SHOCK with Bamford’s signature blue

The watch underneath is the Casio × Bamford GM-5600BWD-1, a $280 square G-SHOCK with a black ion-plated metal bezel and aqua touches on the dial, display and band. Inside, it’s the same tough digital G-SHOCK with 200-meter water resistance, a stopwatch, a countdown timer and an LED light.
None of that changes with a new strap. What changes is how loud the blue gets.
Why swap the resin band for nylon?

Because the aqua finally gets a proper stripe. The stock band carries Bamford’s blue as lettering. The Bark & Jack runs it along both edges of a 24mm black nylon strap, so the accent frames the case instead of sitting on it.

Nylon is also softer against the wrist and a lot more casual than resin. I’d wear this one with a T-shirt and save the resin for rainy days.
Casio connectors, no model list

Bamford London ships the strap with connectors for a Casio watch, and since the width describes the nylon rather than your watch, those connectors are what decide the fit.

Bamford sells it right alongside its own G-SHOCK, and that’s the watch I’d buy it for. On any other Casio, it’s a gamble the listing doesn’t settle.
Who should buy the Bark & Jack strap?

Owners of Bamford’s G-SHOCK who want more aqua on the wrist. At $40, it costs about a seventh of the watch and changes its whole mood. That’s a fair deal for a branded strap that comes with its own connectors.
Skip it if you like the resin band’s toughness or want a strap that disappears. This one is meant to be seen.

On the collaboration watch, it carries Bamford’s colors from the case right onto the strap, and I’d call that money well spent.
