rapid ascent warning may or may not reach your ears.
● If you find the DEPTH hand indicating the 58-minute position while you are underwater, you
should either ascend to the surface immediately or, if you choose to remain underwater, not
depend on diving information provided by the watch.
● The watch measures the depth of water on the basis of seawater having a specific gravity
of 1.025. When it is used in fresh water such as lakes, therefore, the displayed depth should
be corrected by multiplying it by 1.025.
Ex. Assuming that the gravity of the lake where you are diving is 1.00
If the watch indicates 29.2 m, the actual depth is:
29.2 m x 1.025/1.00 = 30.0 m
● While you are underwater, none of the buttons will work for safety’s sake.
AFTER DIVING
● After making a dive, be sure to rinse the watch in fresh water, and wash out all seawater,
soil, sand, etc. If dust forms between the case and rotating bezel, the pressure sensor will
not function properly.
● Be sure to wash out soil, etc. sticking to the water contact sensor unit, as this will cause a
malfunction.
● After cleaning the watch in fresh water, be sure to wipe it thoroughly dry to prevent possible
rust on the case.
● If soil, sand, etc. stick in the sensor unit and cannot be washed out, take your watch to the
retailer from whom the watch was purchased or an AUTHORIZED SEIKO DEALER or
SERVICE CENTER.
● Be careful not to expose the watch to solvents such as alcohol and gasoline, as this may
cause a malfunction of the sensors.
