Square-faced G-Shocks sit at the heart of Casio’s range, and the 5600 Series is the classic, no-nonsense option that competes with other tough digital sports watches for durability and everyday wear. This black and red version leans into the retro look, with a high-contrast red display that stands out more clearly than the usual grey-on-black screens, especially in low light.
Who is this for?
Anyone who wants a watch they can wear without thinking about it. The 200m water resistance suits swimming and water sports, and the shock-resistant build is the reason people buy G-Shock in the first place, it shrugs off knocks that would finish a dressier watch. The compact square case also sits flatter on the wrist than many chunky modern G-Shocks, so it works well for daily use.
- 200m water resistance: confidence for pool and sea sessions
- Shock resistance: built for drops, bumps and rough use
- Red digital display: clearer at a glance than darker LCDs
