SEIKO Solar Radio-Controlled Wall Clock, Solar Plus, SF243S, Silver

This solar-powered radio-controlled wall clock has an ultra-long battery life, capable of supplying power for approximately two years on the auxiliary battery alone , even in places where there is insufficient light, and for more than two and a half years when used in combination with solar power generation and an auxiliary battery .

Press the brightness test button on the back of the watch to check whether the brightness is suitable for your situation using the LED lamp on the dial.

*Even if the auxiliary battery is capable of generating sufficient power, it should be replaced approximately every 10 years.

*Please be sure to insert the auxiliary battery before use. Charging by light alone will not function properly.

The metallic silver frame adds a cool touch to offices and public spaces.

The watch is equipped with a sleep second hand function , which detects brightness and stops the second hand at the 12 o'clock position when it gets dark. When it gets bright again, the second hand starts moving again to match the 00 second mark.

*Even while the second hand is stopped, the hour and minute hands will continue to display the correct time.

It creates a quiet environment that won't disturb your sleep, and since the second hand doesn't make any noise when it moves, it creates an environment that is easier to receive radio waves.
