PRECAUTIONS ON USING THE WATCH FOR DIVING

Before diving, make sure that the watch operates normally and be sure to observe the
precautions described below.

BEFORE DIVING

Do not use the watch for saturation diving using helium gas.
To measure the elasped time while you are underwater, always use the rotating bezel.
Check that:

• the second hand is moving at one-second intervals.

• the “•” mark on the case back indicates the expected life limit of the battery. (See “BATTERY
CHANGE” on page 22.)

• the crown is locked tightly in place.

• the buttons are 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.

If there are any malfunctions, we recommend that you contact an AUTHORIZED SEIKO SERVICE
CENTER.

WHILE DIVING

Do not operate the crown and the buttons when the watch is wet or in water.
Take care not to hit the watch against hard objects such as rocks.
Bezel rotation may become slightly stiffer underwater. This is not a malfunction.

AFTER DIVING

Rinse the watch in fresh water after diving and wash out all seawater, soil, sand, etc.
Wipe the watch thoroughly dry to prevent possible rust on the case after cleaning the watch in fresh water.
