The newly leaked Casio GMC-B2100ADS-1ADR will likely arrive next month, in April.
A new leak has now revealed the Casio GMC-B2100ADS-1ADR. This one is a full metal CasiOak with Tough Solar, analog-digital display, and a stainless steel build. A catalog listing hints at an April launch, which likely means the watch is nearing release.

A new leak shared by tipster @morgan_gshock is hinting at another upcoming addition to Casio’s full-metal lineup, this time based on the popular octagonal "CasiOak" design. The model, listed as GMC-B2100ADS-1ADR, appears in a catalog-style render similar to earlier leaks related to the GMW-BZ5000 series.

The image shows a full stainless steel construction, including the case and bracelet. The design follows the classic GA-2100-inspired octagonal bezel, but with a more industrial-style finish. The dial layout is analog-digital, with multiple subdials and applied indices, rather than the simpler digital display seen on square models.

A visible module number "5733" is listed on the spec render as well. The feature column on the left confirms Tough Solar charging, 20 bar water resistance, mineral glass, and a white LED backlight. Shock resistance and standard G-Shock durability features are also present, as expected. The presence of a barcode and "In Package" label implies that this is a finalized retail SKU rather than an early concept render. Similar to the earlier GMW-BZ5000RC leak, an "APR" marker is present near the top of the image, so we can expect a possible April release window.

Compared to resin-based GA-2100 models, this version will be occupying a more premium segment within the lineup. However, pricing is still unconfirmed at the time of writing.
