MRGB2000B1A4 | Black MR-G Watch - G-SHOCK | CASIO

MRG-B2000 Series


My GShock

Introducing the stunning MRGB2000, a proud addition to the MR-G line, the pinnacle of the G-SHOCK brand. The meticulous attention to construction, function, materials, and finishes that is the hallmark of MR-G delivers the strength and beauty that has always been at the heart of Japanese craftsmanship. Cut to evoke the look of a Japanese fan or folding screen, the dial’s perimeter features a simple, yet gorgeous texture. The gentle curvature of a sword blade is echoed in index marks with a grind-mark finish that offers the beautiful edging and curves that only Yamagata Casio’s nano-processing technology can produce. The MRGB2000B-1A4 takes it to the next level with inspiration from Akazonae — the color of the crimson armor worn by elite samurai and associated with gallantry and valor. The G-SHOCK and MR-G logos on the bezel are inlayed with this traditional color of boldness, and it is also used for dial components. The timepiece also layers in the red and black G-SHOCK brand colors to project a unique and timeless sense of strength. Yet function would not be outdone by style in this one-of-a-kind watch, which features radio-controlled calibration and smartphone pairing via Bluetooth® to delight even the most practical owner. The exclusive MR-G module even has a gold-plated retainer plate to reduce electrical resistance. As if this weren’t enough, Sallaz polishing, double-hardening, and a sapphire crystal with anti-reflective coating ensure that every detail of this timepiece exudes power and excellence. Step up to the MR-G, the embodiment of the strength, beauty, and precision that come to life when Japanese technology meets Japanese aesthetics. Returns will only be accepted if product is in original packaging and protectant film is in place.

A colour evoking the all-crimson armour worn by elite samurai units in the Warring States period of old Japan. The way it stood out on the battlefield associated it with those led by valorous commanders, including the Takeda and Sanada troops. Red, a colour signifying strength, is used for the MRG-B2000B-1A4.


striking colour
expressive of strength

Red, as a shade of colour signifying strength since days of old, is captured here using the traditional Japanese hue of deep crimson. Applied to the engraved lettering in the bezel and various parts of the dial, its striking impression is paired with the G-SHOCK brand colour black for an expression of strength to span the ages. Components including the front screws and crown feature gold-coloured IP evoking a samurai commander’s helmet and armour.

Dial design infused with
Japanese aesthetics

Cuts evoking the look of folding fans/screens adorn the dial’s perimeter. For the index, Yamagata Casio’s nano-processing technology is used to apply a grind-mark finish to sharp-edged forms and recesses to evoke the gentle curvature of a Japanese sword blade. Also, light, strong carbon is used for the minute and hour hands to offer resistance to drops and impacts.

Rust-resistant pure
titanium, double-hardened
for scratch resistance

The case and band are made with titanium, a material that is light, rust-resistant, and gentle on the skin. The surface is applied with a deep-hardening process and DLC coating which enhances scratch resistance, and finished with a black exterior brimming with presence.

*The MRG-B2000D features a titanium carbide finish.

The beauty of metal brought out with Sallaz polishing

A flawless mirror finish is achieved on the case and part of the band with Sallaz polishing, considered the ultimate in polishing techniques. Highly skilled artisans carefully apply the technique by hand to give the watch a radiantly attractive gleam.

Clad Guard Structure for durability and operability

The Clad Guard Structure builds shock resistance into the crown and buttons, ensuring toughness and ease of operation while reducing the case size. αGEL® inserted into the head cover of the crown helps to absorb shocks.
