Casio is preparing a stealthy new trio of full metal G-Shock watches, and fans of the brand’s tough, tech-forward designs have plenty to look forward to. Details and images of a so-called Black Tone series have surfaced, pointing to three models with a cohesive black-and-silver theme and a refined, brushed-metal finish. While the name isn’t officially confirmed, the “BT” in each model number strongly suggests Black Tone styling, with a release expected in fall 2025.
The lineup reportedly includes the GM-B2100BT-1A, GMC-B2100BT-1A, and GMW-B5000BT-1—covering hybrid, analog, and digital preferences in full metal form. All three lean into a modern, monochrome identity that still nods to classic G-Shock DNA inspired by the original DW-5000C from the eighties.
Design is the star here. Each model appears to feature a brushed stainless steel bracelet paired with a black ion-plated bezel that’s also brushed for a uniform, premium look. The darker hardware is complemented by black-background “negative” displays on the hybrid and digital models, tying the entire series together with a stealth aesthetic that should appeal to anyone who prefers a subtle, tactical vibe.
Here’s what to expect from each watch:
– GMC-B2100BT-1A: An analog model with a black face, three sub-dials, and a straightforward date display. It takes the popular 2100-series silhouette and keeps things clean and legible while embracing the Black Tone palette.
– GM-B2100BT-1A: A hybrid analog-digital edition with a negative display. This variant adds modern convenience with Bluetooth connectivity and Tough Solar charging, making it an everyday-ready option that blends classic hands with smart, low-maintenance tech.
– GMW-B5000BT-1: The all-digital pick for purists who love the square case lineage. It also offers Bluetooth and Tough Solar, and the negative display completes the dark, full-metal look.
Pricing chatter suggests the GM-B2100BT could land around $550, the GMC-B2100BT around $800, and the GMW-B5000BT around $600. Exact figures and final specifications are still to be confirmed, but the rumored pricing puts them right in line with other premium, full-metal G-Shock releases.
As for availability, the Black Tone series is tipped for a fall 2025 launch, with some reports hinting that an announcement could arrive in the coming weeks. Until Casio makes it official, consider these details preliminary—but the consistent leaks and cohesive styling point to a well-defined lineup that’s nearly ready for prime time.
If you’ve been waiting for a darker, dress-meets-utility metal G-Shock, this series looks like a strong fit. The brushed steel bracelets, black ion-plated bezels, and negative displays deliver a unified look across analog, hybrid, and digital options, while Bluetooth and Tough Solar on select models add practical appeal. Keep an eye out for the final reveal, firm release date, and full specs as Casio gears up for the Black Tone drop later this year.
