Functions
PRT-B70-5ER

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

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.

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.

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.

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.

Tide graph
After entering the local data, the tide graph will be dynamically displayed in a hourly cycle. This allows you to check the tides in order to plan your activity in advance.

Moon phase indicator
After entering the local data, the moon phase and moon age are dynamically displayed on the watch.

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.

Fishing Timer
By using the moon phases, the watch can calculate the best times for fishing and displays them symbolically. This allows you to plan the best time for fishing is in advance.

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

Accuracy
+/- 15 sec

Type of battery
CR2025

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.

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

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.

2 Years - 1 Battery
The battery supplies the watch with sufficient energy for approx. two years.
