Note
xThe stopwatch 1/100-second hand and stopwatch 1/10-second hand move for
the fi rst three minutes of an elapsed time measurement operation only. After that,
both hands stop at the 0 position.
Stopping the elapsed time operation will cause the two hands to move to
the 1/100-second and 1/10-second positions of the stopped elapsed time
measurement operation. Note, however, that the hands will not move when the
stopwatch is stopped if the cumulative elapsed time exceeds 120 minutes.
xThe stopwatch minute hand is a 40-minute retrograde dial. Every 40 minutes (at
the 41st or 81st minute), it reverts back to the 1 position.
xThe stopwatch second hand and stopwatch minute hand move for the fi rst 120
minutes of an elapsed time measurement operation. After that, the second hand
stops at the 0 position while the retrograde minute hand stops at the 40-minute
position.
Hold down the A and B button at the same time for at least two seconds.
Push the Crown back in.
x The second hand should be moving normally at one-second intervals.
Important!
x Timekeeping stops while the crown is pulled out. Correct the current time setting
after performing the above operation.
Crown Operations
Some water-resistant models (100 meters, 200 meters)
have a screw-in crown. When you need to perform a crown
operation, rotate it towards you to unscrew it. Then pull the
crown out. Avoid applying undue force when pulling. The watch
loses its water resistance while the crown is unscrewed. After
performing a crown operation, fully screw the crown back in.
If your watch has a rotary bezel...
You can rotate the bezel to align its ▼ mark with the
minute hand. Then you will be able to tell how much
time has elapsed since aligning the ▼ mark.

stop and the watch will exit the Demo Mode after about three seconds.
