ROTATING BEZEL
1Turn the rotating bezel to align the
“ ” mark to the minute hand.
2When time has elapsed, read the
number on the rotating bezel.
The rotating bezel can show up to 60 minutes of elapsed time.
*Turn the hands past the 12 o’clock marker to determine whether the watch is set for the A.M.
or P.M. period. If the calendar changes when the hour hand passes the 12 o’clock marker,
the time is set for A.M. If the calendar does not change, the time is set for P.M.
*When setting the hands, first set them to a time a few minutes earlier than the correct time,
and then advance them to the exact time.
* It is necessary to adjust the date at the end of February and 30-day months.
Example: Starting time : 10:10
Finishing time : 10:40
Elapsed time : 30 minutes
Elapsed time
*For safety’s sake, the rotating bezel rotates only counterclockwise, so that the time measured
is never shorter than the actual elapsed time.

•the strap or bracelet is securely fastened to the watch case.
•the buckle keeps the strap or bracelet firmly secured to the wrist.

TO PRESERVE THE QUALITY OF YOUR WATCH
●Repair of diver’s watches requires special expertise and equipment. If you find that your diver’s
watch is malfunctioning, therefore, never attempt to repair it but immediately send it to a nearby
SEIKO Service Center.
■TEMPERATURES
+60°C
-10°C
Your watch works with stable accuracy within a temperature range of 5°C
and 35°C (41°F and 95°F). Temperatures over 60°C (140°F) may cause
battery leakage or shorten the battery life. Do not leave your watch in very
low temperatures below –10°C (+14°F) for a long time since the cold may
cause a slight time loss or gain. However, the above conditions will be
corrected when the watch returns to normal temperature.
●After checking that the crown is screwed in completely, rinse the watch in fresh water, and wash out all
seawater, soil, sand, etc.
●After cleaning the watch in fresh water, be sure to wipe it thoroughly dry to prevent possible rust on the
case.
