    This Self-Charging Edifice model eliminates the need for battery changes through its unique Solar Powered system. Robust enough to power functions, such as its 1/100th Chronograph, 29-City World Time and Daily Alarm, the EQS500C-1A1 is not only intelligent, it's tough also. The black IP solid stainless steel case with mineral glass is water resistant up to 100 meters.
