What is a G-SHOCK Smart Watch?
A CASIO G-SHOCK smart watch isn’t a typical smart watch. Unlike devices running Wear OS and watchOS, G-SHOCK prioritises reliability – eliminating the need for daily charging, touch screens, or delicate handling.
What makes it ‘smart’? Across the range, you get Bluetooth smartphone connectivity, automatic time sync and a handy phone finder. More advanced models add app integration via the Casio Watches app, step counting, heart rate monitoring, GPS connectivity, and detailed training analysis.
This approach is best summed up as smart where it counts, tough where it matters. You get the core G-SHOCK DNA with 200m water resistance, shock resistance, solar charging – subject to models – and multi-year battery life. The Casio Watches app acts as your central hub. It manages your connected features, your training data, and your watch configuration.
