Casio PRG-300-1A2ER Men's Pro Trek

Full-Auto-LED light 

A twist of the wrist in weak light conditions automatically lights up the display backlight.

Low-temperature resistant (-10 °C) 

Even temperatures as low as -10 °C have no effect on this watch.

Solar Power 

A solar cell provides power for operation.


A built-in direction sensor detects the magnetic north.

Barometer (260 / 1.100 hPa) 

A special sensor measures the air pressure (measuring range: 260/1100 hPa) and presents this on the display in the form of a symbol. This enables early detection of weather trends.

Thermometer (-10°C / +60°C) 

A sensor measures the ambient temperature around the watch and displays it in °C (-10°C /+60°C).

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.

Height Gain 

The height gain sums all the meters you have climbed in a session, so that you can see at a glance the total ascent on a tour.

Altimeter data memory 

Depending on the model, up to 40 sets of elevation data can be stored in the watch's data memory and re-accessed at any time. Each of these data sets consists of a measured altitude as well as the date and time. In addition to the individual altitudes, the maximum and minimum altitudes during a measurement are also stored.

Sunrise/sunset display 

After entering the geographical location, sunrise and sunset times can be displayed for any given date.

World time function 

Displays the current time in major cities and specific areas around the world.

Stopwatch function - 1/10 sec - 1.000 hours 

Elapsed time, split time and final time are measured with 1/10-sec accuracy. The watch can measure times of up to 1000 hours.

Timer - 1/1 min. - 24 hours 

For fans of precision: the countdown timers help you to remember specific or recurring events by giving off an audible signal at a preset time. The time can be set to the nearest minute and up to 24 hours in advance. Ideal for people who need to take medicines every day or those who do interval training.

5 daily alarms 

The daily alarm reminds you about recurring events with an acoustic signal at the time you have set. This model has 5 independent alarms for flexible reminders of important appointments.

Snooze feature 

Each time you stop the alarm, it sounds again after a few minutes.

Button tones on/off 

The button tones for using the mode button can be turned off. This means that the watch no longer beeps when switching from one function to another. Preset alarm or countdown timers remain active when the button tones are deactivated.

Automatic calendar 

Once set, the automatic calendar always displays the correct date.

12/24-hour timekeeping 

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

Mineral glass 

The tough mineral glass resists scratching.

Resin case 

Resin band 

Synthetic resin is the ideal material for wrist straps thanks to its extremely durable and flexible properties.

Battery level indicator 

An indicator shows the current battery level.

Water resistance classification (10 bar) 

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 22810)
