G-Shock's MR-G line exists to answer a question nobody really asks: what happens if you make the toughest watch on earth out of the most expensive materials instead of the cheapest? Thirty years after the first MR-G, Casio just pushed that idea further than it's ever gone, and the result costs more than most of the cars in a Gear Patrol garage feature.
The MRG-B2100HR-1A, nicknamed "Haruka," starts from the familiar octagonal CasiOak case that MR-G collectors already know. From there, everything gets an upgrade most watchmakers reserve for pieces ten times the price. The dial has a dimensional lattice pattern borrowed from kigumi, the Japanese wood-joinery technique used in temple construction, and each one is individually finished in platinum leaf by hand, by a single named craftsman in Kyoto. Because it's hand-applied, no two watches in the 800-piece run are exactly alike.
The part that isn't just decoration
The bezel and bracelet use what Casio calls structural color: a laser carves a microscopic texture into the metal that bends light into shifting blues, greens and copper tones, the same physical trick that makes a butterfly wing or a peacock feather change color depending on the angle. There's no paint or coating involved, which means the finish can't chip or fade the way a dyed or plated case eventually does.
Underneath the ceremony, it's still built like a G-Shock is supposed to be. The case is Ti64 titanium, the bezel uses a cobalt-chrome alloy Casio calls Cobarion that's roughly four times harder than pure titanium, and the movement runs on Tough Solar charging with Multi-Band 6 radio sync and Bluetooth linking to the Casio Watches app. A companion gold-leaf version, the MRG-B2100HS-9A, is limited to just 150 pieces.
Price and availability
Casio has confirmed a Japan price of ¥1,100,000 — roughly $7,000 at current exchange rates — for a November 2026 release, but hasn't announced U.S. pricing or a release window yet. Watches at this production level tend to sell through MR-G's usual boutique and authorized-dealer network rather than general retail, so expect a waitlist once a U.S. price lands.
Why it matters even if you never buy one
Most of what a $7,000 G-Shock teaches trickles down. The structural-color bezel technique and the Cobarion alloy first showed up in cheaper MR-G references before reaching a limited piece like this one, and Casio has a habit of eventually folding its flagship ideas into watches a normal person can actually order. If you want the everyday version of "tough watch that still looks intentional at a desk," our luxury dive watch guide covers steel divers that do a similar job for a fraction of the price, our retro sneaker guide rounds out the same "premium but not precious" wardrobe logic on your feet, and a leather jacket is the outerwear that can actually stand up to a watch this substantial. For a more attainable take on the same instinct to buy something with a story most people won't recognize, see Nivada Grenchen's F77 or Timex's root beer GMT, both a fraction of the price.
