PERPETUAL CHRONO A•T
Mvmt. Cal. No. E65*
NOTE: Under normal conditions, this timepiece will
receive radio signals to automatically update the time
and calendar for the 5 radio-controlled cities (zones)
featured (LAX, DEN, CHI, NYC and LON.) The ‘A-TM’
(alternate) time zone is not radio-controlled but its time
is based from the radio-controlled zones. There may be
conditions in which the radio signal cannot be received. If
a signal cannot be received or the ‘A-TM’ (alternate) time
zone is chosen, the watch will operate normally, but not
sync with the radio signal.
NOTE: After a complete loss of charge or an abnormal
function is noticed, an ALL RESET PROCEDURE and
0-POSITIONING is required. Be sure to set the time
and date after performing these procedures.
RADIO RECEPTION
The timepiece will receive radio signals both
automatically and on-demand. Both the time and calendar
will update based on a chosen radio-controlled time zone
(LAX, DEN, CHI, NYC or LON) and provided you are within
that radio signal zone.
Automatic reception occurs first at 2:00 AM, 3:00 AM and
then if needed, at 4:00 AM. If initial reception is successful,
subsequent reception attempts (3:00 AM or 4:00 AM) will
not be activated.
The “on-demand” reception feature allows the user to
enter the reception mode at his/her convenience. This is
helpful when changing time zones before the automatic
update or if an automatic update was not successful.
NOTE: Radio updating can take up to 15 minutes to
complete. During the update process, the watch must not
be moved as this will prohibit a successful radio update.
For in-depth instructions on the radio reception feature,
please refer to your owner’s guide.
ALL RESET AND 0-POSITIONING PROCEDURE
•
Pull the crown out one ‘click.’
•
Rotate the crown to move the mode hand (6:00 sub
dial) to CHR mode.
•
Pull the crown out an additional ‘click.’ The hour,
24 hour, minute and multi-function hands as well as
the date will rotate to their zero positions currently
stored in memory. The correct zero positions are:
Hour, minute, second and 24 hour: 12:00 (straight up)
multi-function hand (2:00 sub dial): 6:00 (straight down)
date: between 31 and 1, centered in date window
•
Press and hold the upper right (B) and lower right (A)
buttons down simultaneously for 2 or more seconds,
then release them. The hands will move back and
forth and a “beep” sound will tone indicating the ALL
RESET is successful.
•
Press and release the lower right button (A). The
minute and hour hands will move slightly indicating
they are active for setting.
•
Rotate the crown to move the minute, hour and
24-hour hands until they point straight up (12:00).
NOTE: quickly rotating the crown two ‘clicks’
will activate rapid advancement. To stop rapid
advancement, rotate the crown 1 ‘click.’
•
Press and release the lower right button (A). The
second hand will move slightly indicating it is ready
for setting.
•
Rotate the crown in either direction to move the
second hand to the 12:00 position.
•
Press and release the lower right button (A). The
multi-function hand (2:00 sub dial) will move back
and forth indicating it is ready for setting.
•
Rotate the crown in either direction so that the multi-
function hand points straight down (6:00) and the
date indicates between “31” and “1” (centered in
the date window.)
•
Push the crown in two ‘clicks’ to the closed position
next to the case. This completes the ALL RESET and
0-POSITIONING. You must now set the time and calendar.
TO SET THE TIME AND CALENDAR
NOTE: You must first set one of the radio-controlled time
zones prior to setting the ‘A-TM’ (alternate) time zone,
even if you do not wish to use a radio-controlled time
zone. Otherwise, the time displayed will not be correct
for all zones.
NOTE: If you are using one of the radio-controlled time
zones (LAX, DEN, CHI, NYC and LON), and you are in the
signal area for that time zone, the time and date will
update automatically upon receiving a successful radio
update. There may be circumstances however for which
you need to manually set the time and date such as after
an ALL RESET and 0-POSITIONING.
•
Pull the crown out one ‘click.’ Rotate the crown
clockwise or counterclockwise to the radio-controlled
time zone shown nearest you. NOTE: The ‘A-TM’
(alternate) time zone is not radio-controlled.
•
Pull the crown one additional ‘click’ to the time setting
position. The second hand will rotate to the SMT
(daylight saving time) “on” or “off” setting position set
in memory.
•
Press and release the upper right button (B) to move
the second hand to indicate SMT “ON” or “OFF.”
•
Press and release the lower right button (A). The
second hand will rotate to the 12:00 position and the
minute hand will move slightly indicating the minute,
hour and 24-hour hands are active for setting.
•
Rotate the crown in either direction to set the
current time in the radio-controlled zone chosen. Pay
particular attention to the 24-hour hand to ensure
the correct AM or PM time is set (quickly rotating the
crown two ‘clicks’ will activate rapid advancement).
•
Press and release the lower right button (A).
The multi-function hand (2:00 sub dial) will move
indicating the date is active for setting.
•
Rotate the crown one ‘click’ clockwise or
counterclockwise to change the date (quickly
rotating the crown two ‘clicks’ will activate rapid
advancement).
•
Press and release the lower right button (A). The
second hand will rotate to the current month of year
and leap year position set in memory.
•
Rotate the crown clockwise to set the current month of
year and leap year as outlined in the graphic below:
•
Press and release the lower right button (A).
The multi-function hand (2:00 sub dial) will rotate
to the current day of week set in memory.
•
Rotate the crown clockwise or counterclockwise to
set the correct day of week.
•
Push the crown in two ‘clicks’ to the closed position
next to the case. This completes setting the time
and calendar.
TO SET THE ALTERNATE TIME ZONE
NOTE: One of the radio-controlled time zones must
be set prior to setting the alternate time zones.
• 
Pull the crown out one ‘click.’ Rotate the crown
clockwise or counterclockwise until the mode
hand (6:00 sub dial) points to “A-TM.” The hands will
rotate to the current “alternate time” set in memory.
• 
Pull the crown out one additional ‘click’ to the time
setting position. The second hand will rotate to the
SMT (daylight saving time) “on” or “off” setting
position set in memory and the minute hand will
move back and forth slightly.
• 
Press and release the upper right button (B) to move
the second hand to indicate SMT (daylight saving
time) “ON” or “OFF.”
• Rotate the crown clockwise to advance or
counterclockwise to decrement the time in one
hour increments.
• Press and release the lower right button (A) to
advance the minutes in 15 minute increments.
• 
Push the crown in two “clicks.” This completes
setting the alternate time zone.
TO INITIATE ON DEMAND RECEPTION
There may be times when you need to initiate radio
reception rather than waiting for the automatic update
to occur.
Be sure the mode hand (6:00 sub dial) is pointing to
one of the radio-controlled cities (LAX, DEN, CHI, NYC
or LON) and you are within that same radio signal
reception region.
Press and hold the lower right button (A) for
approximately 2 seconds and release. The second hand
will rotate to the “RX” position.
Place the watch on a stable surface where it will not be
disturbed during the update process. The update process
can take up to 15 minutes to complete, depending on
signal strength.
After the update process is complete (successful or
failed), the watch will return to normal operation.
If you are having difficulty receiving radio reception and
are in one of the radio-controlled zones featured on this
timepiece, try a different location such as by a window
that is facing your nearest radio transmission tower (as
indicated in your instruction manual).
