These G-SHOCK GBM-2100A new colorways have arrived, and CASIO has done something genuinely interesting with their metal-bezeled CasiOak formula. These aren’t lazy color swaps — there’s real design thought here that makes them worth your attention.
Three new variants were released in Japan this August, joining the G-SHOCK GBM-2100 family. The pricing strategy makes sense: 37,400 yen each, matching the original models. That translates to about $250 in the U.S. market, keeping these watches accessible while delivering meaningful updates.
The standout feature lies in the dial patterns. While the original GBM-2100 models featured vertical striping, these new releases have horizontal rectangular patterns that create a striking visual contrast. The GBM-2100A-2B has a blue dial with a positive LCD display, and the GBM-2100A-4B has a burgundy dial with an inverted LCD. The GBM-2100A-8B completes the trio with a gold dial that beautifully catches the light.
These pattern changes may be subtle, but they demonstrate CASIO’s understanding that collectors want more than just color variations. The horizontal lines create a completely different visual texture that works particularly well with the octagonal case architecture.
All three models maintain the core DNA of the original GBM-2100 series. They have stainless steel bezels paired with black resin bands, which balance durability with comfort. The Tough Solar charging system eliminates the need for battery replacements, and Bluetooth connectivity keeps your watch synced with your smartphone.

With water resistance up to 20 ATM, these watches are suitable for serious water activities. The dual LED backlight ensures readability in low-light conditions, and the hands shift function prevents the analog hands from obstructing the digital display.
The Bluetooth implementation here feels purposeful rather than gimmicky. Through the CASIO Watches app, you can access world time for 38 cities, automatic time adjustment, and easy function setup. The power-saving mode extends battery life when needed, and five daily alarms help you manage your schedule.
The stopwatch measures with 1/100th-second precision and has a countdown timer that goes up to 60 minutes in one-second increments. All of these features work seamlessly with the analog-digital display layout that defines the 2100 series.
CASIO has struck an interesting balance with these releases. The metal bezel elevates the perceived quality without pushing the price into luxury territory. The biomass plastic bands demonstrate environmental consciousness without compromising functionality.
The case dimensions remain at 49.3 x 44.4 x 11.9 mm, keeping the watch substantial yet wearable. At 72 grams, the watches feel substantial without becoming burdensome during extended wear.
Priced at $250, these watches compete directly with mid-tier sports watches from traditional manufacturers, offering G-SHOCK’s legendary durability. The metal bezel provides visual weight, justifying the price premium over basic G-SHOCK models.
The August release date in Japan suggests that they will be available globally within months. Early sightings at U.S. retailers confirm that international distribution plans are already in motion.
