The 12.8 mm profile sports a stainless steel band and a mixed material case, including a negative LCD and a tonal dial layout that differentiates each model. The collection introduces silver models GST-B500D-1A and GST-B500D-1A1, the latter showcasing an all-black dial. The silver GST-B500AD-3A boasts a forest green dial, while the GST-B500GD-9A features a gold strap and case contrasted by a black dial and gold-tinted hour markers. A uniquely-designed 3D face distinguishes the GST-B500 lineup and hones G-SHOCK’s innovative design while retaining key performance aspects integral to the brand. Each timepiece exhibits mineral glass and a Neobrite lume, G-SHOCK’s proprietary technology offering luminescent effects activated in low-light environments.
The range adapts design elements from the GA-2100 and GST-B400 models — specifically the LCD, now consolidated at the lower right of the dial, additionally incorporating Tough Solar power and a Bluetooth smartphone link. Weighing approximately 143 grams, the GST-B500 timepieces integrate interactive mechanisms like auto time adjustment via Bluetooth, 200-meter water resistance, world time access in up to 300 cities and a phone finder feature that syncs with smartphone apps. All featured models are shock-resistant and come equipped with dual LED lights.
