Shock resistant

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


A built-in direction sensor detects the magnetic north.

Thermometer (-10°C / +60°C) 

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

World time function 

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

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. - 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.

5 daily alarms

The daily alarm reminds you about recurring events with an acoustic signal at the time you have set. You can also activate hourly time signal that indicates each full hour. This model has 5 independent alarms for flexible reminders of important appointments.

Snooze feature 

Each time you stop the alarm, it sounds again after a few minutes.

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.

Automatic calendar 

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, scratch-resistant mineral glass protects the watch against unsightly damage.

Stainless steel resin case 

Resin band 

Synthetic resin is the ideal material for wrist straps thanks to its extremely durable and flexible properties.

2 Years - 1 Battery 

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

Water resistance classification (20 bar) 

Perfect for free diving without scuba gear: the watch is water resistant to 20 bar / 200 metres. The metres value does not relate to a diving depth but to the air pressure used in the course of the water resistance test. (ISO 22810)
