EDIFICE
Edifice watches range from basic chronographs to more advanced models with more computerized movements. Many Edifice watches utilize Tough Solar, Casio's brand name for solar-powered batteries. More advanced models are "Waveceptors" which can calibrate themselves with atomic clocks via radio wave signals. Some models have Bluetooth connectivity which enables them to be monitored via a smartphone and to share chronograph data. The display of the watches in the Edifice range is variable from a purely analog display to a display combining analog and digital displays (also called Ana-Digi).
Edifice sponsors Honda's motorsport division Honda Racing, Nissan's motorsport division Nismo, TOM's Racing Team, the Japanese Inter Proto Series and etc.
