New: Casio releases G-SHOCK MRG-B5000R

The Casio G-SHOCK MRG-B5000R will be priced at SGD 4,299 inclusive of GST. Available in selected G-SHOCK stores from 2 February 2024.


This novelty is a followup to the MRG-B5000B released in 2022 And is basically the same watch, but with a different band. The case is the same as the MRB-B5000B-1DR model, with the gold accented black DLC case. The gold is an IP finishing and flourishs as accents on the frames of the dial as well as on the side buttons.

The band is now a soft, pliable and flexible material called Dura Soft. And Casio claims that it is extremely stable against discoloration, staining and deterioration.

Pricing-wise, the new MRG-B5000R is less than the 2022 MRG-B5000B-1DR, coming in at just a tad below SGD 4.3k vs SGD 5.9k.

Release information

Casio Computer Co., Ltd. announced today the release of a new addition to the MRG line, the flagship of the G-SHOCK brand of shock-resistant watches. The new MRG-B5000R inherits the iconic shape of the very first G-SHOCK — representing the brand’s point of origin — and features a highly comfortable Dura Soft band.

Based on the concept of delivering “the ultimate in toughness-driven watches,” the MR-G line sits at the pinnacle of the G-SHOCK brand, incorporating state-of-the-art technology and master metalworking techniques. Inheriting the iconic form of the original G-SHOCK, the original MRG-B5000 was released in 2022. Featuring a bezel with the Multi-Guard Structure to enable precision polishing, the watch employed cutting-edge materials including COBARION®, a super-hard alloy, finished with master polishing craftsmanship. With features such as these, it has proven very popular as the flagship model of the G-SHOCK brand.

The new MRG-B5000R builds on the MRG-B5000, employing a soft, comfortable Dura Soft band to offer flexible ease of use befitting the flagship line of the G-SHOCK brand and deliver suitability for both formal occasions and active situations. The Dura Soft band offers strong resistance to discoloration, staining, and deterioration over time, while insert-molding of titanium components also enhances the strength of the band’s connection to the case. The band features a soft, comfortable textural feel, offering a snug fit even when engaging in rigorous activities. A one-touch, 3-fold titanium clasp adds stylish flair to the design.

The watch design is an homage to the color scheme of the DW-5000C-1B, the gold-accented version of the very first G-SHOCK. A diamond-like carbon (DLC) coating is applied to the case and a gold IP finish to the side buttons. The face features gold accents as well. The band incorporates textured patterns inheriting design motifs still going strong since the very first G-SHOCK, including “SHOCK RESIST” symbols and the brick pattern. While inheriting design elements from the original model, the watch combines characteristic G-SHOCK toughness and beauty with a look all its own.
