Functions
PRT-B50-4ER

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.

World time function

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

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.

Smartphone Link

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.

Hand Moving Function

With a push of a button, hands are moving and permit a free visibility of functions like stopwatch or date.

Phone Finder

Misplaced your smartphone? All it takes is the push of a button on your watch and the smartphone sounds an alarm.

Automatic calendar with Date, Day and Month

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 band

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

Battery change indicator

An icon appears when it is time to change the battery.

2 Years - 1 Battery

The battery supplies the watch with sufficient energy for approx. two years.

Water resistance classification (10 bar)

Perfect for swimming and snorkelling: the watch is water resistant to 10 bar according to ISO 22810.
