You may have the watch confi gured for Auto Receive of the time calibration signal
(page E-26), which will cause the time to be adjusted automatically according to your

You are in an area where signal reception
is not possible for some reason.
See “Approximate Reception Ranges”.

Charging
■
The watch does not resume operation after I expose it to light.
This can happen after the power level drops to Level 3 (page E-15). Continue
exposing the watch to light until the
x
Second Hand
starts moving normally (at one-
second intervals).
The
■
x
Second Hand
starts to move at one-second intervals, but then suddenly
returns to moving at two-second intervals.
The watch probably is not suffi ciently charged yet. Continue keeping it exposed to
light.
