•Hand installation procedure
1) Install the date and day hands at
desired marker positions,
respectively.
2) Pull out the crown to the second
click, and turn it clockwise until the
date hand shifts.
3) Install the 24-hour hand so that it exactly indicates “24” on the 24-hour scale. In doing so, take care not to
press down on the movement too hard.
4) Install the hour, minute and second hands in the same manner as you do with conventional watches.
5) Check that all the hands are fixed properly in position.

• Gently push the solar cell unit above the hooking portions
so that they catch the main plate securely.
Notes: •When installing the solar cell unit, take care not
to damage or deform the solar panel.
•After installing the solar cell unit, check that
both the hooking portions catch the main plate
securely.
•If the solar panel is soiled, gently wipe it with a
