●Hour, minute and second hands

•For disassembling and reassembling, use the movement holder for exclusive use with the respective

calibres.

•When installing the hands, place the movement directly on a flat metal plate or a riveting plate.

•How to set the hands

Withthe batteryinstalled, placethe movementdirectly

on a flat metal plate or a riveting plate, taking care not

to press down the hooking portions.

To install the hands:

Turn the crown clockwise until the date changes, and install the hands so that they point to the 12 o’clock

position.

To install the hands so that the date changes more accurately as the hands indicate 12 o’clock midnight:

1) Turn the crown clockwise until the date changes.

2) Give the crown four counterclockwise turns to make the date return to the previous date.

3) Turn the crown slowly clockwise until the date changes again.

4) Install the hands so that they point to the 12 o’clock position.

•Setting position of the movement on the exclusive movement holder

Check that the pins of the movement holder are securely set to the corresponding holes of the

movement.

•Be sure to complete the battery replacement work within three minutes. Otherwise, the

calendar data stored in the built-in IC will be erased.

•Before removing the old battery, be sure to keep a new battery at hand.

•When installing the new battery, take utmost care not to short-circuit the battery connection

(–) and the circuit block cover, as this will also erase the calendar data.

•How to replace the battery

•How to remove the battery

The case ring has numerals printed on it to show the order of disengaging the hooking portions of

the circuit block cover using the tips of the tweezers.

1. Locate the position where numeral “1” is printed on the case ring, and insert the tips of the

tweezers into the gap between the insulator for battery (A) and the circuit block cover, while

taking care not to damage the coil.
