Enjoy Japanese Unique Features in MRG-B5000!

Titanium carbide finish & DLC coating

A titanium carbide finish gives the MRGB5000D a stunning metallic sheen, and the diamond-like carbon (DLC) coating applied to the case and band of the MRGB5000B achieves the iconic black hue of the first G-SHOCK model, but now in metal. Components including the buttons and back cover are finished with gold-colored IP.

Face design true to its roots

A true heir to the distinctive identity of the first-ever G-SHOCK model, the MRGB5000 retains the iconic brick pattern and red line of the original design. The MR-G logo at the lower left of the face also projects a strong presence.

Digital functionality supported with a special module

The MRGB5000 features a special dedicated module based on that of the GMWB5000, with gold plating applied to the retainer plate for the circuit board to reduce electrical resistance.

Solar-powered timekeeping with Bluetooth® and radio control for enhanced accuracy and reliability

Super Illuminator

High-brightness LED backlight for maintaining watch readability in the dark

Official Casio Description. These breakthrough timepieces are a study in metal craftsmanship. The case and bezel are made of Ti64-based super-hard titanium alloy, while the band is made of another special titanium alloy, DAT55G, that is both three times harder than pure titanium and highly workable. The bezel top is crafted in COBARION®, a cobalt-chrome alloy four times harder than pure titanium.
The bezel alone consists of 25 different components, each individually polished for a stunning detailed texture. The state-of-the-art Multi-guard Structure incorporates flat springs and silicone buffers to the multi-component bezel, ensuring outstanding shock absorption to protect the dedicated MR-G module with gold-plated retainer plate.
