Full Metal Blue Sapphire

Bold black with real blue sapphire accents

Defined by the ongoing commitment to delivering ultimate toughness with bold creativity, G-Shock presents the GMW-B5000SB, carrying the “Gem Accents” theme established by the 30th Anniversary and 'Dream Project' references. This real blue sapphire brilliance, brought to life with G-SHOCK toughness, gives the familiar exterior of the square B5000 series 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.
