Casio releases the MRG-G1000HT , a 20th anniversary model to commemorate the original launch of its flagship MR-G series in the G-SHOCK line.

Employing the theme of tsuiki, a traditional Japanese metalworking technique, Casio designed the new MRG-G1000HT in collaboration with a third-generation master artisan in the field, Bihou Asano. A limited run 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.

Casio boldly combined practicality and beauty under the theme of tsuiki in the design of the new MRG-G1000HT, while also realizing the MR-G concepts of extreme toughness and highly refined elegance.

In collaboration with Bihou Asano, Casio produced a watch with a stately appearance and a beautifully pounded finish achieved through meticulous workmanship. Asano is a master tsuiki artisan who has created works for the Kyoto State Guest House and participated in restoration work of items designated as Important Cultural Properties in Japan.

For the bezel and the band, Casio produced a distinctive luster by applying special Japanese “Oboro-gin” (silver-grey color) finish traditionally used for sword accessories and ornaments. On the screws and buttons, the watch also features an “Akagane” (copper color) finish, which was used to give Japanese traditional armor and handicrafts their distinctively deep brilliance.

Learning from these traditional metalworking techniques, Casio gave the entire MRG-G1000HT a dignified and attractively brilliant finish worthy of its status as a 20th anniversary model, 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-G1000HT 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 .

About Tsuiki

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.
