Casio to Release G-SHOCK MR-G with a Gold and Indigo Design Embodying the Beauty of Japan

Limited Edition of Only 300 Watches Worldwide Featuring a Hammered Finish by Bihou Asano, a Third-Generation Master Artisan

December 6, 2016


Tokyo, December 6, 2016 — Casio Computer Co., Ltd., announced today the release of the MRG-G1000HG, a 20th anniversary model to commemorate the original launch of its flagship MR-G series in the G-SHOCK line. Employing gold and indigo design elements, which have been widely used in traditional Japanese artwork and architecture, Casio designed the new MRG-G1000HG to give a splendid and dignified impression. A limited edition of 300 watches will be sold worldwide.

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 feel of G-SHOCK, which conveys its shock-resistant performance. MR-G has gained popularity among adults who want to enjoy a G-SHOCK for many years to come.

Embodying the beauty of Japan, the new model features gold and indigo design elements, enjoyed by the Japanese since ancient times and found extensively in Japanese artwork and architecture. The watch is splendidly finished using cutting-edge technologies. The gold ion plating on the bezel, case, band, and back cover was applied after deep-layer hardening, while the indigo accents were rendered using a blue diamond-like carbon (DLC) finish.

In order to realize the MR-G concepts of extreme toughness and highly refined elegance, Casio chose tsuiki,* a traditional Japanese metalworking technique that combines high degrees of both practicality and beauty. The bezel and the center row of the band on each watch were finished by Bihou Asano, a third-generation master tsuiki artisan. He applied the traditional hammered treatment to each piece, giving the final product a profound sense of originality. Asano has created works for the Kyoto State Guest House and participated in restoration work for items designated as Important Cultural Properties in Japan.

* tsuiki is a metalworking technique by which a sheet of metal is hammered out thinly into a three-dimensional shape. Historically it was used to make copperware and other metal containers, as well as armor and helmets, which needed to be made both thin and strong. Nowadays, the technique is applied to produce components for rail cars, aircraft, and other items.

Casio also gave the MRG-G1000HG outstanding technical specifications worthy of a 20th anniversary model. This status is denoted by a metal plate at the 10 o’clock position engraved with “20th LIMITED” and a serial number engraved on the back case.

Like the MRG-G1000 model it is based on, the new MRG-G1000HG comes with an advanced timekeeping system that receives both Global Positioning System (GPS) satellite signals and radio wave time-calibration signals, and features Dual Dial World Time, which displays times in two cities simultaneously.

This traditional metal-hammering technique was developed for use in the formation of such items as armor and copperware by striking metal sheets with a hammer. Bihou Asano, a master in this technique, finishes the surfaces of the bezel and the center row of the band on this elegant MR-G model by hand with a hammer, thus giving each watch an original appearance and achieving a dignified, delicately beautiful exterior.


Tsuiki Master Bihou Asano

Bihou Asano was born in 1943 into an old Kyoto family of tsuiki metal hammering masters. In addition to pursuing creative activities under the name Heian Bihou III, he engages in the repair and reproduction of National Treasure metal artworks. While continuing to work in his inherited artistic tradition, he was pleased to collaborate in developing this product due to his appreciation of the MR-G vision of product manufacturing as an ongoing challenge.
