The MR-G design capturing the blue radiance of ice caves & a Full-metal G-SHOCK featuring blue sapphire gemstones
As MR-G, the flagship line of G-SHOCK, celebrates its 30th anniversary, the MRG-B5000SA is born under the banner of the Blue Rose Project. For this completely unique timepiece, engineers embraced the ultimate challenge: making the impossible possible. Drawing inspiration from the “super blue” world of ice caves found in Iceland’s largest glacier, the design incorporates a variety of blue hues reflecting the spirit of polar exploration.
A Full-Metal defined by the ongoing commitment to delivering ultimate toughness with bold creativity, G-SHOCK has embraced a definitive challenge with the Blue Rose Project. Inspired by a “Gem Accents” theme, the GMW-B5000SB incorporates the brilliance of blue sapphire gemstones to offer even more refined strength and beauty.
BLUE ROSE PROJECT
Taking its name from the blue rose, the symbol of a miraculous feat that makes the impossible possible, the project is a story of challenge — the very essence of the G-SHOCK identity. The powerful beauty of blue sapphire gemstones represents bold ideas that defy convention, brought to life through originality and innovation. This has culminated in a timepiece pioneering new realms of toughness in a way never before imagined.
FEATURES
Blue sapphire gemstones gleaming with blue radiance
The mystical blue glow of Iceland’s ice caves is created by highly pure glacial ice compressed over countless years, allowing only blue light to pass through. A pair of blue sapphire gemstones adorn the bezel, capturing the beautiful radiance of this stunning “super blue” sight.
A pair of large two-carat unset gemstones capture the spectacular blue hue of the glacial landscapes. The sapphire gemstones feature beautiful finishing from every viewing angle, with original eight-facet cuts inspired by the iconic G-SHOCK form and meticulous polishing.
These lab-grown blue sapphires offer a level of quality control difficult to achieve with natural gemstones. Grown as ingots over the course of several months, only the sections with exceptional color consistency, clarity, and minimal inclusions are carefully selected.
Exquisite, blue-toned structural beauty
The bezel is formed from multiple separate components instead of a single piece. Each part is polished prior to assembly to give the watch a distortion-free finish, right down to the most challenging spots like recessed portions. A dedicated Multi-Guard Structure was developed specifically for this watch to meet the rigorous MR-G standards of shock resistance while employing a multi-component structure. αGEL® protects the blue sapphire gemstones with superior shock-absorption, while suspension components at the four corners and silicone buffers help absorb impacts to the module.
In addition, blue arc ion plating (AIP) is applied to the bezel, blue ion plating (IP) to the four-cornered suspension componentry, and blue vapor deposition to the watch glass made from sapphire crystal, expressing a “super blue” aesthetic across the entire watch exterior. The nuanced color scheme incorporates varying hues of blue, accentuating the radiance of the blue sapphire gemstones.

Pursuing strength and beauty through materials
The top bezel is made with COBARION, an alloy about four times harder than pure titanium, with a brilliant gleam comparable to platinum. The side bezel, case, case back, buttons, and buckle employ a special Ti64 titanium alloy about twice as hard as pure titanium. Special surface treatments enhance wear resistance, helping to preserve the beauty of the metal over time.
The strap is made with Dura Soft rubber, a material that combines exceptional durability with flexibility. The tri-fold deployment buckle is crafted from super-hard materials, including Ti64 titanium.

Special design celebrating the MR-G 30th anniversary
Limited to just 500 pieces worldwide, the MRG-B5000SA features a case back engraved with the “MR-G 30TH” anniversary logo and a serial number. Each watch is presented in special anniversary packaging.
* Due to the screw-lock construction of the case back, the orientation of the logo and lettering on it may not match up perfectly with the dial.
Solar-powered timekeeping with radio control and Bluetooth® connectivity
Smartphone Link and radio-wave time calibration deliver automatic time adjustment. Solar-power charging ensures stable operation of watch functions.

Sapphire crystal
Scratch-resistant, highly transparent, and treated with anti-reflective coating to deliver excellent clarity and readability.
FEATURES
Blue sapphire brilliance reflecting strength
As a symbol of the Blue Rose Project, four lab-grown blue sapphires are set in the bezel dimples, adding dazzling radiance to the watch. Second in hardness only to diamonds, these round brilliant-cut gemstones shine with beautiful sparkling gleams from every angle. Exuding a serene sense of intelligence, the blue-toned brilliance expresses the spirit of G-SHOCK with its ongoing passion for achieving strength and beauty.
Full-metal shock-resistant structure with no compromise on beauty
The original full-metal shock-resistant structure of the GMW-B5000, which protects the module with a stainless-steel bezel and case while employing fine-resin buffering components to help absorb impacts, has been updated to accommodate the blue sapphire settings. The holes bored through the bezel dimples are fitted with stainless-steel mounting bases and rubber buffering components that support each gemstone securely from below.
The watch features the same screw-lock case back as the very first G-SHOCK and a three-pronged lug that provides a strong, stable band connection.
* Due to the screw-lock construction of the case back, the orientation of the logo and lettering on it may not match up perfectly with the dial.
All-black design handsome with blue accents
A black IP bezel, inverted LCD, and black soft urethane band create a bold, powerful all-black design that accentuates the striking presence of the blue sapphire gemstones and the blue line tracing the watch’s face.
The stainless-steel bezel features a complex form that demands a high degree of manufacturing precision, requiring forging, cutting, and polishing processes to be repeated dozens of times. Mirror and hairline finishes are carefully applied to individual surfaces, emphasizing the textural sophistication of the hard metal. The result is the sharp, sculptural beauty of this one-of-a-kind full-metal design.
Solar-powered timekeeping with radio control and Bluetooth® connectivity
Smartphone Link and radio-wave time calibration deliver automatic time adjustment. Solar-power charging ensures stable operation of watch functions.
