IN CASE OF AN UNUSUAL MOVEMENT OF THE SECOND HAND

Energy depletion forewarning function (Second hand movement and watch state)

Movement of the second hand shows the state of the watch (working functions).

...2-sec interval movement/5-sec interval movement are brought about

When the energy stored in the watch runs low, the energy depletion forewarning function will work.

When the energy stored in the watch runs low, charge the watch by expose to light.
