PRECAUTIONS
Before diving
● Do not use the watch for saturation diving using helium gas.
● Check that:
• the time and calendar are appropriately set.
• Rotating Bezel turns counterclockwise smoothly (the rotation must not be too loose
or too tight) and the “ ” mark aligns with MINUTE hand.
• CROWN is locked tightly in place.
• there are no visible cracks in the crystal.
• the strap is securely fastened to the watch case.
• the buckle keeps the strap firmly secured to the wrist.
If there are any malfunctions, we recommend that you contact an AUTHORIZED SEIKO
SERVICE CENTER.
While diving
● Do not operate CROWN 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 harder in the water but this is not a malfunction.
