Battery swaps and dead displays have no place on a long shift. The Casio AQ-S820W Solar Analogue-Digital Watch draws its power from light, keeping you on time without routine maintenance.
Its rechargeable battery runs approximately 10 months without light after a full charge, while Power Saving blanks the display in the dark to conserve energy. The 46 g resin case and band stay comfortable all shift.

· Dual Interval Timers: Two countdown timers with auto-repeat alternate between two paces for structured interval training.
