Defined by the ongoing commitment to delivering ultimate toughness with bold creativity, G-SHOCK presents the GMW-B5000SB, inspired by a “Gem Accents” theme. Blue sapphire brilliance, brought to life with G-SHOCK toughness, gives the exterior a striking new look.

The bezel, with its iconic shape inherited from the very first G-SHOCK, is set with four lab-grown blue sapphires, second in hardness only to diamonds. Their round brilliant cut catches the light from every angle, while blue accents around the face echo their striking radiance. The black IP bezel, inverted LCD, and black soft urethane band complete the powerful all-black design, allowing the blue details to stand out.

The original full-metal shock-resistant structure 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. This preserves the original shock-resistant performance while making the blue sapphire design possible. Carefully applied mirror and hairline finishes further emphasize the texture of the hard metal, revealing the sculptural beauty of the full-metal exterior.

Bold black meets serene blue, reflecting the enduring G-SHOCK pursuit of strength and beauty.

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.

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, emphasising 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.

Super Illuminator

The high-brightness full-auto LED backlight offers enhanced readability in the dark.
