Casio Watches

Today, Casio is most commonly known for durable, large sized watches. Especially popular are its dual function LCD and analogue watches, some of which, called Wave Ceptors, receive radio signals daily from an atomic clock to keep accurate time.

G Shock Watches By Casio

G-Shock is a brand of watches manufactured by Casio, known for its resistance to shocks (e.g. hard knocks and strong vibrations). They were, and continue to be, designed primarily for sports and outdoor adventure oriented activity; for example, practically all G-Shocks have some kind of stopwatch feature, countdown timer, light and water resistance. Recent models have become more luxury and design oriented.

Casio Waveceptor Watches

The Casio Wave Ceptor is 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.
