• Case / bezel material: Bio-based Resin / Stainless steel
  
• Mineral Glass
  

The tough mineral glass resists scratching.

• 100-meter water resistance
  
• LED backlight (Super Illuminator)
  

Full auto LED light, selectable illumination duration (1.5 seconds or 3 seconds), afterglow

If the ambient light fades, a turn of your wrist illuminates the watch display particularly brightly.

• Tough Solar (Solar powered) White

Invisible solar cells in the watch convert light into energy and supply all functions. A rechargeable battery provides the necessary capacity for operation in poor light conditions.

• Low-temperature resistant (–10°C/14°F)
  Even temperatures as low as -10 °C have no effect on this watch.
  
• Time calibration signal reception
  Whether in Europe, North America and Japan or in the outer reaches of Canada, Central America and China - once the watch has been set to the local time, it receives the relevant signal and shows the correct time wherever you are. In many countries, it also sets itself automatically to summer and winter time.
  Auto receive up to six* times a day (remaining auto receives canceled as soon as one is successful)

*5 times a day for the Chinese calibration signal

• Countdown timer
  Measuring unit: 1 second

Countdown range: 24 hours

Countdown start time setting range: 1 minute to 24 hours (1-minute increments and 1-hour increments)

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 24 hours in advance. Ideal for people who need to take medicines every day or those who do interval training.

• 5 daily alarms (with 1 snooze alarm)
  Each time you stop the alarm, it sounds again after a few minutes.
  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.
  
• Hourly time signal
  
• Battery level indicator
  An indicator shows the current battery level.
  
• Power Saving (display goes blank and hands stop to save power when the watch is left in the dark)
