Since G-SHOCK’s launch in 1983, the brand has continued to evolve in its pursuit for outstanding toughness and functionality. This is demonstrated with the release of these compact, smaller, and thinner G-STEEL models, first of their kind. This model GSTB600-1A still maintains the G-STEEL characteristics with its metal bezel structure, but more condensed at 11.4mm. The case has also been reduced in size to 42mm diameter. This is a watch that can be worn in both casual and business settings. Delivering an all timepiece that offers toughness, design, and fashion. - Module No. 5724 - 41.4 x 42.3 x 11.4mm Case Size - 60g Weight - Shock resistant (G-SHOCK) - Tough Solar (Solar powered) - Double LED light: LED light for the face (Super Illuminator, selectable illumination duration (1.5 seconds or 3 seconds), afterglow).
