PRECAUTIONS FOR DIVING
BEFORE DIVING

• the watch operates normally.
• 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 time and date are properly indicated.
• the small second hand is moving at one-second intervals.
• the log data of the previous two dives is recalled properly.
• all the hands for diving measurement are reset to “0” position.
While the small second hand is moving at two-second intervals, or when the DEPTH hand
points to the 58-minute position after all the hands are reset to “0” position, the watch will
not measure the depth. In these cases, replace the battery with a new one. (See “BATTERY
LIFE INDICATOR”)
If there are any malfunctions, do not use the watch for diving. We recommend that you
contact an AUTHORIZED SEIKO SERVICE CENTER.
● If the temperature of the water is much lower than the air temperature (for example, if the

measure the depth accurately. In this case, soak the watch in water for approximately 5
minutes before starting to dive.
● If the watch is used in places where atmospheric pressure or temperature changes sharply,
