・How to install hands
Place the movement directly on a flat metal plate or
the like to install the hands.
Note: How to procedure hands Day transmission wheel
①The state of movement is confirmed by the position of
a right picture.
Pull out the crown to the second click position and
rotation. The position is setting.
②Dial setting.
③
Install the Day calendar hand at the first position.
④Install the Date calendar and small second hands at the
12 o'clock position.
⑤Pull out the crown to the second click position and
rotation it clockwise the change date.
⑥Install the 24hour and hour and minute hands at the
12 o'clock position.
(2)Day calendar (Retrograde) hand first position
・Be quick in Day calendar hand
The hand instantaneously returns from B position
to A position when one week passes.
(3)Winding stem
