Inspiration from an ancient Japanese artform grants this titanium G-SHOCK distinction and sophistication. The flagship MR-G line exemplifies the brilliance and protection of luxury G-SHOCK watches, and that luxury takes a bold turn with the kigumi-inspired MRGB2100D-1A.
A veritable master class in metal craftsmanship, the titanium G-SHOCK MRGB2100D-1A features case and bezel components made with the hard titanium alloy, Ti64. The bezel top is fashioned from COBARION, an alloy that is four times harder than pure titanium, giving this silver G-SHOCK a brilliant gleam comparable to platinum. The band is made of another special titanium alloy, DAT55G, which is both extremely hard and highly workable. We make the most of the extra-hard metal materials to create ultra-smooth mirror finishes and apply titanium carbide (TiC) coating for even greater scratch- resistance. These intricate details further the G-SHOCK reputation for ultimate protection and imbue this luxury G-SHOCK watch with class and style all while granting you peace of mind.
The bezel alone of this silver G-SHOCK consists of 27 different components in an intricate construction unique to G-SHOCK shock- resistant performance. Every single one is individually and meticulously polished to achieve a stunningly detailed textural appearance, ensuring that each titanium G-SHOCK MRGB2100D-1A receives special and specific attention. The state-of-the-art Multi-Guard Structure incorporates buffers between the parts to ensure outstanding shock absorption and protects the dedicated MR-G module with a gold-plated retainer plate. This level of craftsmanship grants the MRGB2100D-1A a special position among other silver G-SHOCK watches.
While the case and bezel of this titanium G-SHOCK are exquisite, the dial’s flare is inspired by the traditional Japanese art of interlocking woodwork called kigumi, which like the bezel of this MRGB2100D-1A involves myriad small components. This traditional art is reflected in the intricately assembled two-part structure of the 12 o’clock index mark and the depth and dimension of the latticework. The tiny openings in the dial — the result of the highest precision process technology — let plenty of light through to the solar panels beneath to keep you up to speed. Casio’s solar-powered system called Tough Solar powers all of the tech under the hood, thus the silver G-SHOCK MRGB2100D-1A combines the look of traditional and ancient art with stunning modern engineering. Luxury G-SHOCK is where innovation meets tradition.
This titanium G-SHOCK masterpiece is more than just a splendid celebration of premium metals. It delivers outstanding functionality with radio-controlled calibration and smartphone pairing via Bluetooth®. Sophistication in a luxury G-SHOCK means continually pushing the frontiers of watchmaking, and that’s nowhere better exemplified than in the silver G-SHOCK MRGB2100D-1A.
Explore the featured elements of the MRGB2100D-1A, and discover the stellar line of luxury G-SHOCK watches in the entire MR-G series.

⭐⭐⭐⭐⭐
I’m extremely impressed with this Casio G-Shock DW-5600! The watch itself is in perfect condition, with a crisp display and all functions working flawlessly. The recycled blue style fabric strap is a game-changer — it’s comfortable, durable, breathable, and looks fantastic against the gray resin case. The silver buckle is high-quality and secures perfectly. Seller shipped quickly with excellent packaging. Communication was fast and friendly. This is a top-tier seller — trustworthy, detail-oriented, and clearly passionate about watches. I’ll definitely be back for more! Highly recommended.
Great communication and willing to work with me to strike a deal that fit my budget.
This was my first luxury watch purchase to cap off a year of personal and professional milestones and I couldn’t be happier! It’s an absolutely gorgeous watch, was shipped quickly, was packed well, and I feel secure knowing I bought it from an AD and am backed by Longines’ warranty! It’s everything I hoped it would be and I look forward to many years of use!
Awesome experience. Quick delivery.
This is my first luxury timepiece, and the overall feel is exceptional. The brand itself carries a strong heritage of quality and craftsmanship. The service provided by TimeMachinePlus was outstanding—professional, efficient, and focused on delivering a smooth and pleasant purchasing experience. Any issues or concerns were handled promptly and with priority. Overall, an excellent level of service, complemented by the added confidence of a manufacturer-backed warranty.
