FUNCTION AND FEATURE GUIDE
Modules Cases
Full Auto EL Backlight Shock Resistant
Automatically deactivates the Auto EL Backlight function when surrounding light is sufficient, and activates it under dim light or dark conditions. Shock-resistant construction protects against impact and vibration.

Temperature Measurement
Water Resistance

A built-in temperature sensor measures temperature.


The "BAR" value indicates the number of atmospheres to which water resistance is ensured. 20 BAR means water resistance to 20 atmospheres. Watches marked "200m" have the same water resistance as 20 BAR watches.
Moon Age Display
Mineral Glass
The moon age and phase are shown on the display based on your current latitude and longitude.
Hard glass resists scratching.
Tide Graph Display
Resin Band
Tidal movements are displayed graphically based on your current latitude and longitude, and the tidal interval.
Sunrise, Sunset Time Display  
Sunrise and sunset times are displayed based on your current latitude and longitude.

Stopwatch
Accurate measurement of elapsed time with the touch of a button. The fraction indicates the unit of measurement, while the time figure indicates the maximum time measurement.
Daily Alarm, Hourly Time Signal
The daily alarm sounds each day at the time you set. The value indicates how many daily alarms are available. The hourly time signal causes the watch to beep every hour on the hour.
Full Auto Calendar
Allowances are made automatically for months of different lengths, and even leap year.
12/24-hour Timekeeping
Times can be displayed in either a 12-hour or 24-hour format.
Low-Temperature Resistant
The timekeeping module is designed for operation at very low temperatures. The value indicates the lowest temperature at which the module will operate.
*–10°C resistant does not apply to the direction sensor.
