With Casio's non-stop, self-adjusting Wave Ceptor Timepieces, you don't have to worry about replacing batteries because they're Solar Powered and you'll have confidence of always knowing the correct time via Atomic Timekeeping Technology. Several times per day, these watches receive the official US government time via a time calibration signal from the atomic transmitter in Ft. Collins, CO. This eliminates the need to manually set the time and date, adjust for daylight saving time or leap years once the user's home city is set.
