Casio GW-M5610U Operation Manual

The Wave Ceptor (Multiband 6) atomic timekeeping feature works by allowing your watch to receive a radio signal containing time information and use it to keep its time setting accurate. An automatic time calibration signal receive operation is performed, and the time and day settings are adjusted between midnight and 5:00 a.m. Once a signal receive operation is successful, no more auto receive operations are performed that day. The watch can receive signals from various locations, including Japan, China, the U.S., U.K., and Germany.

Was this helpful? Does the Casio GW-M5610U watch require a battery replacement, or is it solar powered?

Your watch is solar powered and runs on power supplied from a rechargeable (secondary) battery that is charged by a solar panel. The solar panel is integrated into the face of the watch, and power is generated whenever the face is exposed to light. The special rechargeable battery used by your watch is not intended to be removed or replaced by you. If you feel that the amount of operation provided by charging is too short, you should contact your original retailer or CASIO service center.
