Operating Instructions
ASTON 1/5 CHRONOGRAPH
A chronograph combines two time-keeping functions. It incorporates
a device to measure intervals of time independent of the regular time
shown on the dial. Your ESQ by Movado Aston Chronograph may be
used to time events up to two hours in duration, in 1/5 of-a-second
increments.
NOTE: After 2 hours of continuous running, the chronograph will stop
and reset automatically to preserve battery life.
Setting the Time:
1. Pull crown out to position 3. (Watch will stop.)
2. Turn crown in either direction to move hands to desired time.
Be sure to take AM/PM into account so that date changes at midnight,
not noon.
3. Push crown back in to position 1. (Watch will restart.)
NOTE: To set time to exact second, pull crown out to position 2 precisely
when small seconds hand
S
reaches <<60>> position. (Watch stops.)
Adjust time to one minute ahead, and take an accurate time signal, from
a radio news station, for example. When audible tone signals exact time,
immediately push crown back in to position 1. (Watch will restart, now
set to the exact time.)
Setting the Day:
1. Pull crown out to position 3. (Watch will stop.)
2. Turn crown in either direction to move hands forward or back. Each
time the hands complete a 24-hour revolution and pass midnight,
Day indicator hand
F
will move ahead or back by one day.
3. Once correct Day has been reached, set hands to correct Time,
following instructions above.
4. Push crown back in to position 1. (Watch will restart.)
Setting the Date:
1. Pull crown out to position 2. (Watch will keep running.)
2. Turn crown clockwise to move hands forward. Each time the hands
complete a 24-hour revolution and pass midnight, the date shown in
Date display
D
will advance by one number.
3. Once correct Date has been reached, push crown back in to position 1.
CAUTION: Never set the date when the hands are between 9:00 PM
and 12:30 AM, while automatic date changing is in progress. Doing so
could damage the calendar mechanism.
