2. Continuous Usage Time
This watch will continue to run for about 1 month (until the insufficient charge warning function is activated) once it has been fully charged.
This is roughly based on the conditions of use indicated below.
•Diving (water depth measurement): Twice/week (30 min./dive)
•Alarm: 30 seconds/day
•Chronograph measurement: 1 hour/week
•EL light: 4 seconds/day
*The continuous usage time of the watch becomes shorter the more often the alarm, chronograph and other functions are used. In addition, the continuous usage time is further reduced by infrared communication.
*Since the water sensor is activated when the watch gets wet even when not diving, the continuous usage time becomes correspondingly shorter.
