Limited Edition G-SHOCK 40th Anniversary Model with Gassan

The top range of the G-SHOCK line-up, the MR-G series, is also getting in on the 40th anniversary celebrations of G-SHOCK with a limited edition model created in collaboration with Japan’s leading sword-smith Gassan. This limited edition G-SHOK 40th anniversary model with Gassan draws inspiration from Gassan’s attention to detail, precision and art, with elements applicable to MR-G’s spirit of timekeeping.

This G-SHOCK 40th Anniversary MR-G Gassan presents a timepiece made of re-crystallised hybrid titanium, integrating multiple layers of titanium Ti64 and pure titanium.

Traditional Sword-Making Meets Modern Timekeeping Technology

Sadanobu Gassan, a descendent of one of Japan’s most renowned swordsmith lineages, has carved his mark for a timepiece that is a symbol of elegance. The watch comes with a titanium band that is designed to resemble a sword’s nakago (tang), personally marked by Gassan with a yasuri-me (file mark) pattern and carved with his signature. The middle segment of the band is carved with the motto of the Gassan clan ???? (devoted to sword-forging), along with the characters ?(forged) and ? (tempered). The handmade aspects of these models make each timepiece a distinctive work of art.

G-SHOCK 40th Anniversary MR-G Gassan Watch Built and Quality

The watch is made from re-crystallised titanium, a material that integrates multiple layers of titanium Ti64 and pure titanium in a way that the differences between the materials become visible when they are re-crystallised. Taking advantage of this feature, G-SHOCK created a unique tempered ayasugi hada pattern under the supervision of Gassan.

Depending on the sword making school, different patterns manifest themselves when a sword blade is forged. The bezel, band, and back cover are coated with a newly developed blue-gray IP coating to reproduce the bluish iron color that is the color of high-quality swords. The case is made of pure recrystallized titanium and finished with deep hardening and a TIC coating. The letters “G-SHOCK” “40TH” are engraved on the plate on the side of the case at 10 o’clock.
