2 year warranty

Full automatic LED light

With a twist of the wrist the dial is automatically illuminated by a light-emitting diode in case of poor lighting.

Low temperature resistant (-10 °C)
Even temperatures as low as -10 °C do not damage the watch.

Solar function
The solar cells power the watch autonomously and ecologically. Excess solar energy is saved in a battery.

Digital compass
The built-in direction sensor detects magnetic north.

Barometer (260 / 1,100 hPa)
A special sensor measures the atmospheric pressure (measuring range: 260/1,100 hPa) and displays it as a symbol on the display. It is thus possible to know the weather trend in advance.

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

Altitude detection up to 10,000 m
A pressure sensor detects changes in atmospheric pressure and converts the data into altitude up to 10,000 m.

Accumulating altitude detection
Altitude accumulation adds up all the meters traveled uphill, allowing you to quickly know the total altitude difference for a hike.

Altimeter data memory
Up to 40 data relating to altitude can be saved in the watch's data memory, depending on the model, and can be recalled at any time. Each of the data is composed of a measured elevation and the corresponding date and time. In addition to the individual quotas, the maximum and minimum quotas detected during a measurement are also stored.

Sunrise and sunset display
By indicating the geographical position it is possible to display the sunrise and sunset time for any date.

World time function
The world time function shows the time in up to 29 time zones.

Stopwatch - 1/10 sec - 1,000 hours
Elapsed time detection. The fraction indicates the unit of measurement while the number indicates the maximum measurement time.

Timer - 1/1 min. - 24 hours
For anyone who loves precision: countdown timers help you remember particular or repeating events by emitting an acoustic signal at the set time. The time can be set in minutes and up to 24 hours in advance. Particularly practical for daily medication intake or interval training.

5 daily alarms
The daily alarm reminds you of events that repeat every day by emitting an acoustic signal at the set time. This model is equipped with 5 independent alarms to individually remind you of important appointments.

Snooze function
Every time you stop the alarm it starts ringing again after a few minutes.

Activating/deactivating the sound of the keys
With a special button it is possible to deactivate the sound of the lyrics. After deactivation, no acoustic signal will be emitted when switching from one function to another. However, the set alarms or the countdown timer remain active even after deactivating the button sound.

Automatic calendar
Once set, the automatic calendar always displays the exact date.

12/24 hour format
The time can be displayed in 12 or 24 hour format.

Mineral glass
The mineral glass, robust and more resistant to scratches, protects the watch from unsightly damage.

Resin case

Resin strap
The resin is synthetic, an ideal material for straps thanks to its extreme resistance and flexibility.

Battery level indicator
The indicator shows the current charge level.

Water resistance rating (10 bar)
Perfect for swimming and snorkeling: the watch is waterproof up to 10 bar/100 meters. The meter specification refers not to a diving depth but to the atmospheric pressure that was used as part of the waterproof approval. (ISO 22810)
