Converting Light from Fluorescent Lamps and More
The original Casio solar-charging system reduces the need for regular battery replacement
Tough Solar
This original Casio solar-charging system employs solar panels that convert light even from fluorescent lamps and other sources, combined with an internal rechargeable battery. It generates ample power for smooth operation of power-hungry functions, from measurements to radio wave reception, Bluetooth® connectivity, lights, and alarms. Also includes a Power-Saving function that automatically engages when the watch is left for a certain period in a dark location.
Shadow-Dispersing Solar Panel
Ample power for functions such as GPS signal reception is ensured by dispersing the power generation loss due to the shadows of watch hands and so on across multiple solar cells to raise light-reception efficiency. This has also enabled the use of dimensional dials with low light transmissivity and designs with large hands and hour marks.
Solar Charging Through Inset Dials
The solar-receptive area in inset dials alone transmits enough light to power the watch, enabling face design with a greater degree of freedom.
Solar-Assisted Charging
Use USB charging for training functions such as GPS tracking and heart rate monitor, as well as smart functions such as notifications and step tracker. Time display is powered solely by solar charging, even when battery runs low.
