New design, as a tribute to 40 years of G-SHOCK. The GA-2140RE-1AER is a limited edition that celebrates 40 years of G-SHOCK history. Its strap and bezel are made from bio-based resins, while Eric Haze's anniversary logo is engraved on the case back. When the LED is activated, the logo appears as a silhouette. Four stars symbolising the 40th anniversary are engraved on the strap loop. The design is based on the GA-2140 line and shows you all the milestones in G-SHOCK history on the strap.
