Casio to Release G-SHOCK MR-G with Crimson Accents, Embodying Strength and the Beauty of Tradition

Tough Metal Construction for a Solid Look; GPS Hybrid Wave Ceptor System Keeps Accurate Time Anywhere in the World

March 10, 2017


Tokyo, March 10, 2017 — Casio Computer Co., Ltd., announced today the latest addition to the flagship MR-G Series in the G-SHOCK line of shock-resistant watches. The new MRG-G1000B-1A4 employs the GPS Hybrid Wave Ceptor* timekeeping system, and features crimson accents that evoke the red lacquered armor that once signified elite samurai.

* A timekeeping system that receives both GPS signals and radio wave time-calibration signals transmitted from six stations worldwide, to keep accurate time anywhere in the world. In areas where radio waves are available, the watch prioritizes reception of radio wave signals. In areas without radio wave coverage, the system corrects the time using time data from GPS signals.

The MR-G series offers the ultimate in tough watch design. It combines a sense of quality evoked by finely finished titanium with the distinctively solid look of a G-SHOCK to convey its shock-resistant performance. The MR-G series has gained popularity among adults who want to enjoy a G-SHOCK for many years to come.

The new MRG-G1000B-1A4 features crimson accents that evoke the red lacquered armor which signified the power and strength of elite samurai during the Warring States period of old Japan. Crimson accents are applied to the bezel and dial logos, second hand, and inset dial hands, adding to the solid and rugged look of the MR-G. The large side buttons, crown, and front screws are chiseled from metal and finished with gold ion plating, highlighting the black and red theme and lending a refined look to the watch.

For the ultimate in toughness, the bezel, case, band, and back case feature deep-layer hardening to increase hardness, on top of which is applied a diamond-like carbon (DLC) coating. Sallaz polishing, considered the ultimate in polishing techniques, is applied to achieve a flawlessly radiant and attractive finish.

The face is made from sapphire crystal with an anti-reflective coating for scratch resistance and optimum readability, while multidimensional index marks are formed using precision molding techniques developed by Casio. This diligent attention to small details results in a stylish looking watch.

The MRG-G1000B-1A4 comes with a timekeeping system that receives both GPS satellite signals and radio wave time-calibration signals, and features Dual Dial World Time, which displays times in two cities simultaneously.
