Casio and Spanish rapper Rels B are releasing the GM-S2110B-8ARLSB on June 18 — a blacked-out octagonal G-Shock with concert-inspired caseback engravings and a custom aluminum Rels B flight case. It's the pair's second collab after the full-metal GM-2110.

Casio is dropping another G-Shock collaboration with Spanish rapper Rels B, this time on the smaller GM-S2110 platform. The new GM-S2110B-8ARLSB, teased via a 3rd party Instagram account (geesgshock), is set to release on June 18.

Rels B (real name Daniel Heredia Vidal) is a Latin rapper and producer from Palma de Mallorca, Spain, who also goes by Skinny Flakk, which explains the "ARLSB" suffix in the model number.

The watch is based on the octagonal GA-2100 silhouette, finished in an all-dark colorway with a brushed metal bezel. What sets it apart from the standard GM-S2110B-8A is a caseback engraved with the Rels B and G-Shock logos alongside tour artwork, just like the rapper's concert imagery, as hinted at in the Spanish-language video ("de sus conciertos"). It ships in a custom aluminum flight case branded with the Rels B logo.

This isn't the duo's first time working together. Rels B previously became a G-Shock ambassador to help launch the GM-2110, a full-metal model with an elegant design alongside durability, released in five colorways — that was the larger, bracelet-equipped version. The GM-S2110B-8ARLSB moves to the slimmer S-series case, which features a compact size suited for slimmer wrists, with a resin band instead of a metal bracelet.

No pricing has been confirmed yet, though standard GM-S2110B-8A variants typically retail around €130-150 in Europe. Given the custom packaging and engraving, the collab model will likely carry a premium over that.
