You can get the G-SHOCK 2100 shape, toughness, and everyday convenience for far less than MR-G money. The Casio MRG-B2100HR-1A has to justify its price through what cheaper 2100 models do not offer: a hand-finished platinum-leaf dial, unusual titanium alloys, laser-created structural color, and production limited to 800 numbered pieces worldwide.

The watch commemorates the 30th anniversary of Casio’s MR-G line, which launched in 1996 as G-SHOCK’s premium metal-focused range. It is an MR-G anniversary model, not a celebration of the 2100 family itself. Casio lists November 2026 as the international launch window, although retailer timing and availability may vary by market.
The question is whether its materials and finishing offer enough practical and emotional value to make the jump worthwhile.
The dial is the main attraction
The MRG-B2100HR-1A has a dimensional latticework dial inspired by kigumi, a traditional Japanese method of joining wooden components without nails or other metal fittings.
Metal-leaf artist Hiroto Rakusho applies platinum leaf to the dial components. Casio says every stage of the foil-stamping process is done by hand, with Rakusho personally adding the finishing touches. Powdered platinum leaf creates variations in shimmer and shading, so individual watches will not look completely identical.
Casio says each of the 800 watches is individually hand-finished by Rakusho.
The bezel and bracelet take a more technological approach. An ultrashort-pulse laser creates microscopic surface textures that produce structural color rather than relying on conventional pigments. The effect shifts with viewing angle and reflected light, making it difficult to judge fully from promotional photographs alone.
The materials go beyond a standard G-SHOCK
Casio uses COBARION for the upper bezel and DAT55G for the bracelet. The case, case back, buttons, and crown use Ti64 titanium.
Casio says COBARION is approximately four times harder than pure titanium and DAT55G roughly three times harder. Those are comparisons between materials, not independent tests of how the finished watch will withstand years of scratches and wear.
Titanium helps keep the weight down, while Casio chose the specialty alloys and DLC coating to help resist wear and preserve the watch’s appearance. The bezel is also built from 27 separate components, allowing its individual surfaces to be polished before assembly. Buffers in Casio’s Multi-Guard Structure help the full-metal exterior retain the shock resistance expected of an MR-G.
None of this changes what the watch can do day to day. It changes how the watch is made, and where much of its price goes.
It still works like a practical G-SHOCK
Beneath the elaborate exterior is a familiar set of high-end G-SHOCK conveniences. The MRG-B2100HR-1A has Tough Solar charging, Multi Band 6 radio time synchronization, and Bluetooth connectivity through the Casio Watches app. Radio reception or a paired phone can correct the time automatically; without either, Casio rates its accuracy at ±15 seconds per month.
Other specifications include a sapphire crystal with an anti-reflective coating, Super Illuminator LED lighting, automatic hand-position correction, a full auto-calendar, shock resistance, magnetic resistance, and 200-meter water resistance.
These are useful features, but they are not the main reason to buy this edition. The premium is concentrated in the construction, materials, finishing, and limited production around them.
It is still a substantial watch
Casio lists the MRG-B2100HR-1A at 49.5 × 44.4 × 13.6 mm and 122 grams on its solid titanium bracelet. That gives it a 122-gram, full-metal wrist presence rather than the feel of a resin GA-2100.
The bracelet has a tight-lock, one-press, three-fold clasp, and the watch uses a screw-lock crown. They are fitting details for a flagship 2100 rather than a standard model with a decorative dial.
Price and availability
Casio’s Japanese announcement lists a November 13, 2026 release in Japan and a price of ¥1,100,000 including tax. Those are Japan-specific details. Casio’s international product page gives a broader November 2026 launch window; pricing and availability elsewhere will depend on the market.
The MRG-B2100HR-1A makes the most sense for someone who already loves the 2100 design and wants an unusually elaborate version of it. Its hand-finished dial, complex metalwork, and limited run are the appeal.

If your priorities are toughness, solar charging, automatic time correction, or Bluetooth, less expensive G-SHOCKs can meet them. This watch’s practical advantages are more focused: titanium construction, specialty alloys, and coatings chosen to help preserve its appearance. The rest of the premium buys craftsmanship and exclusivity, not a dramatic increase in everyday function.
