Functions
EL Backlight (with Auto Light)
An electro-luminescent panel causes the entire face to glow for easy reading. Auto Light automatically turns on the EL backlight when the watch is tilted towards your face for reading.

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 resistance does not apply to the direction sensor.

Duplex LCD
Two liquid crystal panels make it possible to select from among different display patterns.

Barometic Pressure Measurement
A built-in pressure sensor measures barometric pressure, which is shown on the display.

Temperature Measurement
A built-in temperature sensor measures the temperature.

Compass
A built-in direction sensor detecs magnetic north.

10,000 m Altimeter
A pressure sensor detects changes in the air pressure and converts the result into an altitude up to 10,000 m.

Stopwatch function (1/100 - 24HR)
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.

5 Daily Alarms
The daily alarm reminds you about recurring events with an acoustic signal at the time you have set. You can also activate hourly time signal that indicates each full hour. This model has 5 independent alarms for flexible reminders of important appointments.

Battery Indicator Display
An icon appears when it is time to change the battery.

Full Auto Calendar
Allowances are made automatically for months of different lengths, in case date corrections for leap years are required.

12/24-hour Timekeeping
Times can be displayed in either a 12-hour or 24-hour format.

Leather/Cloth Band

Water resistance classification (10 bar / 100m)
Perfect for swimming and snorkelling: the watch is water resistant to 10 bar / 100 metres. The metres value does not relate to a diving depth but to the air pressure used in the course of the water resistance test. (ISO 2281)
