10 000 m altimeter

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.

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.

Stopwatch function - 1/100 sec. - 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.

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.
