PRO TREK Climber Line: serious outdoor gear for nature lovers

The case, band (PRW-35LD) and resin back cover are made from biomass plastic, demonstrating consideration for the environment.

The PRW-35TLD and PRW-35LD are the first Casio watches to feature a luminous LCD for improved practicality in outdoor situations at night.

The underside of the digital display is luminous, improving visibility at night.

When illuminated with a mountaineering headlamp (equivalent to 200 lumens) from approximately 5 cm above the watch for approximately 1 minute, the light will continue to glow for approximately 1 hour.

The PRW-35TLD features a sapphire crystal, stainless steel bezel, and titanium band.

The bezel and band are treated with titanium carbide, which not only makes them scratch-resistant but also improves their color development.

The PRW-35LD uses a dark coyote color for the band, making it suitable for the outdoors.

In terms of functionality, it is equipped with a triple sensor that can measure direction, altitude/barometric pressure, and temperature.

In addition to its measurement functions, it also has practical functions such as Multiband 6 and Tough Solar.

This model is packed with high functionality and practicality, improving visibility at night and making it suitable for a variety of situations, including camping.

・ Tough Solar (solar charging system)
・ 10 ATM water resistance
・ Radio wave reception function: Automatic reception (up to 6 times/day) (up to 5 times/day for Chinese radio waves) / Manual reception, Received radio waves: JJY, Frequency: 40kHz/60kHz (Fukushima/Kyushu station compatible model) Received radio waves: WWVB, Frequency: 60kHz Received radio waves: MSF/DCF77, Frequency: 60kHz/77.5kHz Received radio waves: BPC, Frequency: 68.5kHz
* If the home time setting is set to a city that can receive radio waves, the station corresponding to the city will be received.

The time difference is set according to the city you select.

Luminous LCD: By storing light from a headlamp or other source and illuminating the entire face, visibility in dark places is improved.
- Orientation measurement function: Measures 16 orientations and orientation angles (0 to 359°) (in 1° increments),
graphically displays north, south, east and west, continuous orientation measurement (60 seconds),
bearing memory (records the orientation of a target (destination) and indicates the recorded direction),
magnetic declination correction function, orientation correction function (2-point correction)
- Barometric pressure measurement function (measurement range: 260 to 1,100 hPa, 1 hPa increments),
barometric pressure trend graph (42 hours),
pressure difference indicator (± 10 hPa),
barometric pressure trend information alarm (arrow and sound alert when a significant change in barometric pressure occurs)
Altitude measurement function/relative altimeter (measurement range: -700 to 10,000m, 1m unit),
altitude difference indicator (± 3,000m),
altitude trend graph, measurement interval setting function (every 5 seconds/2 minutes)
* Every 1 second for the first 3 minutes only, altitude memory (manual memory for up to 30 measurement dates, times, and altitudes),
automatic recording data (maximum/minimum altitude, auto total (ascent/descent) memory),
14 mountain climbing record data (maximum/minimum altitude, auto total (ascent/descent memory))
- Temperature measurement function (measurement range: -10 to 60°C, in 0.1°C increments)
World time: 48 cities (31 time zones, daylight saving time setting function) + UTC (Coordinated Universal Time) time display Sunrise and sunset time display Stopwatch (1/10 seconds, 1000 hour counter, split)
・ Timer (set unit: 1 minute, maximum set: 24 hours, measured in 1 second units)
5 time alarms (1 with snooze alarm) Time signal Battery indicator Power saving function (display turns off after a certain period of time in the dark to save power)
- Fully automatic calendar - 12/24 hour display switching - Low temperature resistance (-10℃)
- Operation sound ON/OFF switching function - LED backlight (with full auto light, super illuminator, afterglow function, afterglow time switching (1.5 seconds/3 seconds))
Operating time from full charge without solar power generation When using functions: Approximately 7 months When in power saving mode: Approximately 23 months
* If radio reception is not performed, it will operate with normal quartz accuracy (average monthly difference of ±15 seconds)

* The altimeter is a relative altimeter that converts changes in air pressure into altitude.

If the air pressure changes due to weather conditions, the measured altitude will also change.
