Receiving sensitivity, reception area, strength, and thinness.
Pursuing further reliability of radio solar, we have arrived at the thin movement "TOUGH MVT. <Tough Movement>".
Hybrid mount mechanism
By carefully calculating the combination of materials (metal and resin) used for each part and their weight/strength balance and optimizing their placement, we have improved the durability against "deflection" and "lateral slip" that occur at the time of impact.
Needle position automatic correction function
A unique algorithm detects and confirms the position of the second hand, minute hand, and hour hand.
If there is a deviation between the time counter in the LSI and the reference position of the hands, each hand is automatically corrected to the correct position.
Tough Solar
Casio's unique solar charging system that converts light into power. Stable drive of various heavy-load functions such as radio wave reception function and needle position automatic correction function.
Multiband 6
Receiving standard radio waves from 6 stations around the world. Automatic time adjustment in Japan, North America, Europe, and China.
