Our take on the Casio G-Shock GD-B500-1ER

The Casio G-Shock GD-B500-1ER is a solar-powered digital watch with a stainless steel case and a silver-grey finish. It offers a stopwatch, alarm, multiple time zones, and an integrated light for visibility. Its 49mm case and 13mm thickness give it a substantial presence, but the solar power means you never need to replace a battery. Compared to other G-Shock models, it stands out for its metal construction and eco-friendly solar charging, though it lacks the advanced sensors of some pricier G-Shock variants. It suits those who want a rugged, low-maintenance watch for sports and everyday wear.
