1. Notes on Water-Resistance
a. This diver’s watch has the water-resistant construction for diving up to 200m
and withstands water pressure up to 200m deep. The crown is screw-lock
type. Tighten the screw completely before use.
b. All maintenance services including battery replacement must be carried out
by a Citizen Service Center.
c. Subject the watch to a water-resistance check at the time of battery replace-
ment or every one or two years to maintain the water-resistance of the watch
2. Pressure Sensor
•Never disassemble the sensor cover which protects the pressure sensor.
• Be careful that foreign objects such as sand, dust or other matter does not
enter into the sensor. If such objects have entered into the sensor, wash it
away with fresh water. Do not use alcohol, gasoline, thinner or other chemi-
cal substances.
• If you cannot clean the sensor, take the watch to a Citizen Service Center.
