Casio has designed the new MRG G1000HT watch that explores the theme of tsuiki, a traditional Japanese metalworking technique.

This is described as a 20th anniversary model to commemorate the original launch of the flagship MR-G series in the G-SHOCK line.

Casio designed the watch in collaboration with a third generation master artisan in the field, Bihou Asano. A limited run of 300 watches will be sold worldwide.

The MRG series claims to offer 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,” the company stated, adding that MRG has gained popularity among adults who want to enjoy a G-SHOCK for many years to come.

Casio says it has 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 has produced a watch with a “stately appearance and a beautifully hammered fish 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 a special Japanese silver grey finish traditionally used for sword accessories and ornaments.

On the screws and buttons, the watch also features a copper color finish.

Tsuiki is a metalworking technique in 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.
