A Casio Wave Ceptor WV-200DE watch. The Multi-Band 5 indicates that it can receive time calibration signals from five radio towers in the world
The Wave Ceptor series (Sometimes stylized as 'wave ceptor' or 'WAVE CEPTOR') is a line of radio-enabled watches by Casio. Wave Ceptor watches receive time signals from various government time services around the world. These signals transmit the time measured by atomic clocks accurate to one second in millions of years. By synchronizing daily with the signals, the Wave Ceptor watches achieve high accuracy, using a traditional quartz crystal to keep time between synchronizations. Some radio watches, including some Wave Ceptors, are solar-powered, supported by a rechargeable battery[1] with a lifetime of about 10 years; such a watch should keep perfect time for about ten years with no adjustment. Some models have a fully digital display; others have hands to indicate the time.
Radio-controlled watches require no setting of time, date, or daylight savings time adjustments, as they attempt automatic synchronization at least once every 24 hours, typically at midnight. Free-running Wave Ceptors, like other commercial quartz timepieces, are typically accurate to better than 15 seconds per month; daily synchronization ensures 500 ms per day accuracy.
Aug 30, 2014 Another problem is the inadequacy of the instructions - minute and barely readable, but even worse: there's a missing step, explained below. This can lead to time-wasting mistakes when setting the casio watch. So beware of these watches, unless you are willing to take risks with your money, and spend time re-setting after faults.

This watch does not have a city code that corresponds to the UTC offset of –3.5 hours. Because of this, the radio-controlled atomic timekeeping function.

Most Wave Ceptor watches feature a gauge to measure signal strength to aid the user in receiving a time signal. The number of receivers which the watches can tune to vary according to watch model; most current watches can tune to any one of several signals around the world. In Europe, the claimed reception range is approximately 1,500 kilometres.
Locations[edit]
Casio watches synchronise to radio time signals from one or more of six low frequency time signal transmitters. The 60kHz signals from different transmitters are not compatible with each other; a watch designed for WWVB only cannot receive MSF.
Japan
Watches can receive signals from two JJY transmitters:
The 40kHz signal from Mount Otakadoya, near Fukushima (Ohtakadoyayama).
Pinook mini massager pads. The 60kHz signal from the Haganeyama Transmitter at Mount Hagane (Haganeyama).
China
Watches receive the 68kHz signal from BPC at Shangqiu.
United States Hyundai eon era plus.
Casio Wave Ceptor User's Manual
Watches receive the 60kHz signal from WWVB at Fort Collins.
United Kingdom
Watches receive the 60kHz MSF at Anthorn.

Germany
Watches receive the 77.5kHz DCF77 at Mainflingen.
As an example, Casio Wave Ceptors using modules 3353 and 3354, such as the WVA-440, can tune to signals from both DCF77 (Germany) and MSF (UK). The two submodels use the same electronics module, but with a soldered jumper selecting preferential tuning first to DCF77, or to MSF. This is default behaviour after a factory reset; the user can choose to use either one of the two transmitters with either module, although this limits use when travelling within Europe.[1]
Multi-Band 6[edit]
A Casio G-Shock GW-9200J 'Riseman' watch incorporating Multi-band 6 technology
A Casio watch featuring Multi-Band 6 indicates that it can tune to any of the six signals of the low frequency radio towers.[2][3]Some of the Casio G-Shock line of watches have Multi-Band 6 technology. The earlier Multi-Band 5 system could not receive the signal of the Chinese radio tower.
Other radio watches[edit]
Japanese manufacturers Seiko and Citizen Watch, and German manufacturers Junghans and Eurochron, also make radio-controlled watches.
