| The newly leaked Casio GMC-B2100ADS-1ADR will likely arrive next month, in April. |
The rumor mill is spinning again for G-Shock enthusiasts, and this time, the focus is squarely on one of the most beloved designs in the brand’s modern catalog. If you thought the stainless steel treatment was reserved only for the square-bodied retro classics, a new leak suggests Casio is about to change the game.
A fresh tip from the reliable leakster @morgan_gshock has surfaced online, hinting at a significant expansion of Casio’s full-metal lineup. The new model, reportedly listed under the product code GMC-B2100ADS-1ADR, appears to be the premium iteration that fans of the octagonal "CasiOak" have been waiting for.
A Heavyweight Champion in Stainless Steel
The leaked catalog-style render reveals a watch that takes the iconic, rugged silhouette of the GA-2100 (famously nicknamed the “CasiOak” for its octagonal bezel resembling the Audemars Piguet Royal Oak) and elevates it into the luxury tier.
Unlike the standard resin-cased models that have dominated store shelves for years, this version—dubbed the GMC-B2100—boasts a full stainless steel construction, encompassing both the case and the bracelet. The industrial-style finish on the metal gives it a more robust, tool-watch aesthetic that should appeal to collectors looking for everyday durability with a premium wrist presence.
The dial layout remains true to the analog-digital hybrid format that made the series famous, but with notable refinements. Instead of the simpler digital displays found on square models like the iconic 5600 series, this variant features multiple subdials and applied indices, offering a more sophisticated and legible face.
Specifications and a Spring Release Window
For those who scrutinize the technical details, the leak provides plenty of reasons to get excited. A visible module number "5733" is listed on the spec render, confirming that this will be no ordinary fashion piece.
According to the feature column visible in the leak, the GMC-B2100ADS will pack the usual G-Shock durability essentials:
- Tough Solar: Ensuring you never have to worry about battery changes.
- 20 Bar Water Resistance: Good for swimming, snorkeling, and high-impact water sports.
- Mineral Glass: Protecting that detailed dial from scratches.
- White LED Backlight: For visibility in low-light conditions.
Interestingly, the presence of a barcode and an “In Package” label on the render suggests that this is not merely a design concept, but a finalized retail SKU ready for distribution. For those marking their calendars, eagle-eyed viewers noticed an “APR” marker near the top of the image—a detail that mirrored earlier leaks regarding the GMW-BZ5000 series. If the pattern holds, we can likely expect an official announcement with a release window set for April.
The Growing Premium Metal Lineup
This leak arrives as Casio continues to blur the lines between utility tool and luxury accessory. While the resin-based GA-2100 models remain wildly popular for their affordability and lightweight feel, the introduction of the GMC-B2100ADS suggests that Casio is aggressively targeting the premium segment.
By giving the octagonal “CasiOak” the full-metal treatment (similar to what they did with the square GMW-B5000 series), Casio is offering an alternative for collectors who want the modern design language of the 2100 family but with the heft and prestige of stainless steel.
Pricing remains unconfirmed at the time of writing, but given the materials and the module complexity, this model is expected to command a significantly higher price point than its resin-based siblings.
A Look Back at the Leak
The speculation began when @morgan_gshock shared the initial visuals, showcasing the catalog-style render that has since sparked discussions across watch forums. You can view the original post.
Is the “Metal Oak” the New King of G-Shock?
If the GMC-B2100ADS delivers on the promise of the leak, it could easily become one of the most sought-after releases of the year. It combines the best of both worlds: the legendary durability and shock resistance of a G-Shock with the refined aesthetics of a stainless steel sports watch.
While we wait for the official confirmation and pricing details from Casio, the market is already abuzz with anticipation. Whether you are a die-hard square collector or a fan of the newer octagonal designs, this release signals that Casio is listening to the demand for higher-end materials in modern silhouettes.
