※ While the chronograph is used to measure a long period of time, however,
the watch will stop operating before 45 hours..
If the watch is used without being wound up fully, gain or loss of the watch
may result. To avoid this, wear the watch for more than 10 hours a day. If
the watch is used without wearing on the wrist; if it is used on the desk like
a clock, for example; be sure to wind it up fully every day at a fi xed time.

This is an automatic mechanical watch with manual winding
mechanism.
When the watch is worn on the wrist, the mainspring is wound
automatically through normal wrist movement.
The watch can also be wound up by turning the crown. To do so,
unscrew the crown by turning it counterclockwise.
To start the watch after it stops completely, wind it up either by
turning the crown or swinging it from side to side until the sec-
ond hand starts moving. Then, set the time and date before
putting the watch on the wrist.
To wind up the watch, unscrew the crown by turning it counter-
clockwise, and then, turn it clockwise slowly. The watch cannot
be wound by turning the crown counterclockwise.
Once the watch is wound up fully, it operates for about 45 hours.

How to set the time and date（NE88）
Check that the watch is operating, and then, set the time
and date.
The watch is provided with a date function and is so de-
signed that the date changes once every 24 hours. The
date changes around 12 o'clock midnight. If AM/PM is not
properly set, the date will change at 12 o'clock noon.
■ How to set the time and date
CAUTION
○ Do not set the date between 8:00 p.m. and 2:00 a.m.
as this will cause a malfunction.
