Japanese Watch Casio Protrek 

Thank you very much for visiting my page !

-Tough solar (solar charging system)

● 10 ATM water resistant function

Radio wave reception function: Automatic reception (maximum 6 times/day, Chinese radio wave maximum 5 times/day), coverage area: Japan, North America, Europe, China

* If you set the home time setting to a city where reception is possible, you will receive the station that matches the city. The time difference is set by the selected city.

●Needle position automatic correction function

●World time: 29 cities around the world (29 time zones, with daylight saving time setting function) + UTC (Coordinated Universal Time) time display, UTC direct call function, home time city replacement function

●Azimuth measurement function:

・Measure 16 azimuths and azimuth angles (0 to 359°)

・Direction continuous measurement (60 seconds)

・North direction guide function

・Magnetic declination correction function

・Azimuth correction function

Atmospheric pressure measurement function:

・Measuring range: 260 ~ 1,100hPa

・Atmospheric pressure trend graph display (displays the past 20 hours)

・Pressure difference indicator (±10hPa)

・Atmospheric pressure trend information alarm

Altitude measurement function / relative altimeter:

・Measuring range: -700 ~ 10,000m

・Altitude memory (manual memory of up to 30 measurement dates, times and altitudes, automatic recording data: maximum/minimum altitude, auto integration (ascending/descending memory))

・Altitude trend graph

・Altitude difference indicator (±100m/±1000m)

・Measurement interval setting function (every 5 seconds/2 minutes) *Every 1 second only for the first 3 minutes

●Temperature measurement function: measurement range / -10 ~ 60℃

- Stopwatch (1/100 second, 24 hour meter, with split)

Timer (set unit: 1 minute, maximum set: 60 minutes, measured in 1 second units)

● 5 time alarms, hourly signal

-Needle retraction function (manual, automatic (at the time of altitude, atmospheric pressure, temperature measurement))

●Battery indicator display

● Power saving function (In a dark place, the display turns off after a certain period of time has passed, and the needle stops to save power)

● Full auto calendar

● 12/24 hour display switching

Low temperature resistant specification (-10℃)

●Operation sound ON/OFF switching function

-Double LED light (Dial + liquid crystal part; full auto light, afterglow function, with afterglow time switching (1.5 seconds / 3 seconds))

-Driving time without solar power generation from full charge: Approximately 6 months when using functions, Approximately 23 months when using power saving mode

* When radio wave reception is not performed, it operates with normal quartz accuracy (average monthly difference ± 15 seconds).

* The altimeter is a relative altimeter that converts atmospheric pressure changes into altitude. If the barometric pressure changes due to weather conditions, the measured altitude will also change.
