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.

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 damages.

Carbon-reinforced resin casing

Combining resin with carbon—a particularly robust material—creates a casing that is even more stress-resistant and offers even greater protection against external influences, resulting in an extremely high level of durability.

Folding clasp

The watch has a folding clasp.

3 Years - 1 Battery

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