Limited Edition

From the MR-G series, the pinnacle of the G-SHOCK lineup, comes a new design based on the original DW5000C. The trademark square shape is elevated by utilizing special, premium metal materials and artisan craftsmanship that the MR-G series represents.

The new MRGB5000 model features an intricately shaped bezel made up of 25 parts that have been individually polished with Sallaz polishing, which gives the watch a stunning, elegant finish.

A new shock-resistant multi-guard structure increases strength by using stainless steel leaf springs and silicon between bezel parts. The case and bezel are made of high-hardness Ti64 titanium alloy, and the band is made of DAT55G titanium alloy, which is approximately three times harder than pure titanium and provides excellent workability. The top of the bezel is made using the cobalt alloy COBARION®, which is approximately four times harder than pure titanium and has the same brilliance as platinum. The MRGB5000B-1 model enhances the mirror finish of the COBARION® material by adding a glossy finish with black DLC (diamond-like carbon), which is meant to resemble the original black DW5000C. A brick pattern and a red line for the frame around the digital display adorn the screen, which are identifying characteristics of the original DW5000C.

Function-wise, the MRGB5000 also features a special-purpose MR-G module with gold-plated circuit retainer plates to reduce electrical resistance and is also equipped with time signal reception and Bluetooth® communication capabilities for smartphone connectivity.

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.
