Functions
PRT-B50-1ER

Double-Illuminator
Both the digital and analogue areas of the watch face glow when the EL backlight is turned on.

Neo-display
A luminous coating provides long-term illumination in the dark after only a short exposure to light.

Digital-compass
A built-in direction sensor detecs 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.

Steptracker
The watch has a built-in 3-axis accelerometer that counts the steps you take and indicates the numbers on the display.

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

Location Indicator
The location indicator indicates the direction and distance of a previously stored location. This function can be very useful, if you got lost and you want to get back to a cabin, a lake or a car.

Mission Log
After activating the Mission Log function, route and altitude profile are stored in the smartphone and can be displayed on a map. In addition, photos are automatically stored in a Mission Log when they are made during a tour storage.
