Introducing the PRG-340 from the PRO TREK climber line, authentic outdoor gear for nature lovers.
The case, urethane band, and resin back cover are made of environmentally friendly biomass plastic, while maintaining a comfortable fit that fits comfortably on your wrist.
A duplex LCD with separate liquid crystals for the direction display and clock function display increases the size of the compass display and improves readability, creating a functional and beautiful design that makes it easier to understand direction.
Furthermore, it has a rotating bezel that is useful for simple orientation memory.
In addition, by installing a pressure sensor inside the case, the unevenness of the case is reduced and the button is easy to operate, and it also has practical functions such as tough solar.
The functional design creates an outdoor gear look.

・ 10 ATM waterproof function
・ World time: 48 cities around the world (31 time zones, daylight savings time setting function included) + UTC (Coordinated Universal Time) time display
・ Direction measurement function: 16 directions and angles of direction (0 to 359°) Measurement, Continuous direction measurement (60 seconds), Graphic display of north, south, east, west, Bearing memory (1 graphic showing the angle of direction and recorded direction is stored), Magnetic declination correction function, Direction correction function / Barometric pressure measurement function (measurement) Range: 260 to 1,100hPa), atmospheric pressure trend graph display (displays the past 42 hours), atmospheric pressure difference graphic, atmospheric pressure trend information alarm (notifies you with an arrow and sound when a characteristic change in atmospheric pressure occurs) )
・Altitude measurement function/relative altimeter (measurement range: -700 to 10,000 m), altitude memory (up to 30 manual memory for measurement date, time, and altitude, automatic recording data: maximum/minimum altitude, automatic integration (climb) / descent) memory), 14 mountaineering record data (highest/minimum altitude, automatic integration (ascend/descent) memory), altitude difference measurement (-3,000 to 3,000 m), measurement interval setting function (5 seconds/ (Every 2 minutes) *Every 1 second for the first 3 minutes Temperature measurement function (Measurement range: -10 to 60℃)
・Duplex LC display ・Sunrise/sunset time display ・Stopwatch (1/10 second, 1000 hour meter, with split)
・ Timer (set unit: 1 minute, maximum set: 24 hours, measured in 1 second increments)
- 5 time alarms (only one has snooze function) - Time signal - Battery indicator display - Power saving function (turns off the display after a certain period of time in a dark place 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, and afterglow time switching (1.5 seconds/3 seconds))
- Drive time from full charge without solar power generation: Approximately 7 months When using power saving mode: Approximately 27 months *The altimeter is a relative altimeter that converts changes in atmospheric pressure into altitude.
If the atmospheric pressure changes due to weather conditions, the altitude of the measured value will also change.
*When measuring the outside temperature, remove the watch from your wrist to prevent it from being affected by body temperature, sweat (water droplets), direct sunlight, etc.
