Casio Wave Ceptor watches form a line of radio watches by Casio. Wave Ceptor watches are able to calibrate themselves to the correct time by receiving time signals from various government time services around the world. These signals are normally driven directly by ultra-accurate atomic clocks, and so by synchronizing with the signals, the Wave Ceptor watches achieve long-term accuracy - the same accuracy as the atomic clocks that drive the time signals, which is on the order of one second in three million years.

As well as offering completely accurate time, Casio Waveceptor watches adjust for daylight savings and world time. Across a series of bracelet and strap watches, primarily aimed at gents, the Casio Waveceptor range combines analogue and digital time displays to communicate its impressive functionality. Last but not least, every model comes with a significant discount from the RRP, making Casio Waveceptor watches not only accurate but a complete bargain.
