Functions
PRG-240-5ER

Full-Auto Illuminator

Automatically deactivates the Auto EL backlight function when surrounding light is sufficient, and activates it under dim light or dark conditions.

Low-temperature resistant (-10 °C)

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

Solar Power

Invisible solar cells in the watch convert light into energy and supply all functions. A rechargeable battery provides the necessary capacity for operation in poor light conditions.

Duplex LC Display

The duplex LC display is practical and easy to read at the same time. While the upper layer displays the direction of the compass, the bottom layer can show furter measurments and figures simultaneously.

Digital-compass

A direction sensor measures the magnetic north and displays north on the watch, as well as the direction in which you are currently moving.

Altimeter 10000 m

A built-in sensor measures the local air pressure and calculates the current altitude.

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.

Sunlight Indicator

After entering your local data such as date, time and location, the times for sunrise and sunset can be displayed for any other date.

Barometer (260 / 1.100 hPa)

A built-in sensor measures the local air pressure and shows it on the display. This can be helpful, e.g. while hiking, to recognise weather tends at an early stage.

Thermometer (-10°C / +60°C)

A built-in sensor measures the local temperature and indicates it on the display.

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.

World time function

The world time function displays local times in up to 29 different time zones.

Stopwatch function - 1/100 sec. - 24 hours

Elapsed time, split time and final time are measured with 1/100-sec accuracy. The watch can measure times of up to 24 hours.

Accuracy

+/- 15 sec

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.

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 with Date, Day and Month

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

12/24-hour format

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

Direction Bezel

This bezel can be used to determine approximate directions.

Mineral glass

The tough mineral glass resists scratching.

Resin case

The resin housing is the ideal everyday companion. It is durable, lightweight and relatively insensitive to cold, heat or other external influences.

Resin band

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

Buckle

The bracelet is equipped with a buckle.

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 according to ISO 22810.
