A deep-layer hardening process and dark silver AIP® are applied to the recrystallized titanium case to express the color of the Shougeki-Maru: Gai helmet. An engraved metal plate commemorating the G-SHOCK 40th anniversary on the case side at the 10 o’clock position adds a touch of edgy styling, as do the four lab-grown rubies*2 in the bezel symbolizing 40 years.
