[Insufficient Charging Warning Feature]
When the capacity of the rechargeable cell decreases as a result of light not
shining on the solar cell, the second hand switches from 1-second interval
movement to 2-second interval movement (insufficient charging warning
feature). Although the watch continues to keep time accurately at this time, the
watch stops after about 5 days have elapsed after the second hand has
switched to 2-second interval movement. When this happens, charge the watch
by exposing it to light until the second hand returns to 1-second interval
movement.
Notes: • During chronograph
measurement, measurement
stops and the chronograph
second hand is reset to the 0

Note: • Do not subject the chronograph to strong impacts while chronograph
timing is in progress. Subjecting the watch to a strong impact during
chronograph timing or when the chronograph has stopped
automatically after 60 minutes have elapsed can cause the
chronograph minute hand to shift out of position. If this happens, press
button (A) to reset to the 12:00 position before using the chronograph
again.
