| The Casio G-Shock GM-5600BWD-1 with the new Bamford London strap |
Casio G-Shock fans have two reasons to celebrate this week: a brand-new black-and-aqua nylon strap from Bamford London, and the surprise return of the sold-out Aqua Blue edition.
Bamford London has launched the Bark & Jack Black Strap With Aqua Edge, a 24 mm nylon strap designed specifically to dress up the two Casio G-Shock x Bamford London collaboration watches — the original DW-6900BWD-1 and the newer GM-5600BWD-1.
The timing is fitting. The two brands first joined forces on the Aqua Blue strap released alongside the Bamford x G-Shock GM-5600BWD-1 in December 2025, and now they're back "for round two," as Bamford Watch Department put it in a recent Instagram announcement.
What's New in the Black Strap With Aqua Edge?
The new strap is a black nylon NATO-style band with a vivid aqua blue edge running its full length — a subtle nod to the signature "Bamford Blue" that has become the calling card of the collaboration. The loops carry both the Bamford London and Bark & Jack logos, while all the hardware gets a matte black finish to match the all-black cases of both collaboration watches.
Crucially, the strap ships with connectors for a wide range of G-Shock models, including the DW-6900, GM-5600, GM-2100 and GA-2100. According to G-Central, the connectors should also fit the DW-5610, DWE-5600, GA-B2100, GBM-2100 and GM-6900 — though notably not the standard DW-5600.
The Aqua Blue Strap Is Back — While Supplies Last
Perhaps the bigger news for collectors: Bamford London has confirmed that the original Bark & Jack Aqua Blue Strap with Connectors is back in stock. In its Instagram post, the brand teased that it "might have found a box of the original Aqua strap while reorganising," and that it's available while supplies last — a classic line that usually means G-Shock fans shouldn't wait around.
Price and Availability
Both straps are priced at £35 in the UK (around $40 in the US), with worldwide shipping available directly from Bamford London's online store. Buyers outside the UK should keep in mind that local import duties and taxes are the responsibility of the customer, and delivery times may be affected by regional customs controls — a point several commenters on Bamford's Instagram post were quick to raise about shipping to Europe.
As for the watches themselves, the GM-5600BWD-1 remains available through Casio's online stores in markets including the US and the UK, and G-Central notes it's currently listed at a discounted £195.30 in the UK, $280** in the US and **AU$154 in Australia.
Why It Matters
Strap swaps are one of the simplest ways to freshen up a G-Shock, and Bamford's collaboration pieces have become something of a cult favourite thanks to that distinctive blue accent. With the Black Strap With Aqua Edge offering a stealthier alternative to the original Aqua Blue — and the original back from the dead — this is a good week to be a Bamford G-Shock owner.
