Thermometer (-10°C / +60°C)

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

Digital-compass

A built-in direction sensor detecs the magnetic north.

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.

World time function

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

Stopwatch function - 1/100 sec. - 24 hours

Accuracy of measurement up to 1/100 of a second, measuring range up to 24 hours.

Timer - 1/1 min. - 1 hour

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 1 hour in advance. This model has three independent timers - 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.

Automatic hand adjustment

The automatic hand adjustment function checks the home position of the hands every hour and corrects it if necessary — either by adjusting e.g. from shocks or using the influence of magnetism.

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.

Crown button lock
