■POWER SAVE FUNCTION

● This watch is powered by electrical energy generated and stored by the built-in

Kinetic System. The watch also features the “power save function,” which

automatically stops the hands from moving when the watch is not in use for a

certain period of time to minimize the electrical energy consumption. When the

watch is in power save mode, the hands stop moving but the built-in IC continues

to calculate the time and calendar.

● When the watch is in power save mode, swinging the watch several times will

activate the “time relay function,” which automatically resets the watch hands
