PRECAUTIONS ON USING THE WATCH FOR DIVING

Before diving, make sure that the watch operates normally and be sure to observe the precau-
tions described below.
BEFORE DIVING
l Do not use the watch for saturation diving using helium gas.
l Check that:
• the crown is locked tightly in place.
• there are no visible cracks in the crystal or the watch band.
• the strap or bracelet is securely fastened to the watch case.
• the buckle keeps the strap or bracelet firmly secured to the wrist.
• the rotating bezel turns counterclockwise smoothly (the rotation must not be too loose or
too tight) and the " " mark aligns with the minute hand.
• the time and calendar are appropriately set.
• the second hand is operating normally (if not, swing the watch for more than 30 seconds
to wind the mainspring sufficiently).
If there are any malfunctions, we recommend that you contact an AUTHORIZED SEIKO SERVICE
CENTER.
WHILE DIVING
l Do not operate the crown when the watch is wet or in water.
l Take care not to hit the watch against hard objects such as rocks.
l Bezel rotation may become slightly stiffer underwater. This is not a malfunction.
AFTER DIVING
l Rinse the watch in fresh water after diving and wash out all seawater, soil, sand, etc.
l Wipe the watch thoroughly dry to prevent possible rust on the case after cleaning the watch in fresh
water.
