Full automatic Illuminator
Enable this function, and the watch will automatically light up its display when you turn your wrist. Energy saving: the full automatic illuminator only works in the dark.

Resistant to cold
This watch can withstand temperatures as low as -10 °C.

Stopwatch Memory: 60 sets
Data from the stopwatch function can be stored together with the date from the measurement. This memory can store up to 60 of these datasets.

Digital compass
A built-in direction sensor finds the magnetic North Pole.

Barometer (260/1100)
A special sensor measures the air pressure (measuring range: 260/1100 hPa) and shows this with symbols on the display. It should thus be possible to recognize and predict weather trends.

Thermometer
A sensor measures the temperature around the watch and displays it in Celsius. Operation range: -10°C to +60°C.

World clock
The largest cities in the world are pre-programmed in this watch, so you can select current city/town (closest to you, in the same time zone), and the watch automatically shows the correct time.

Sunrise / sunset display
By entering your geographical position, the local time for sunrises and sunsets are shown, for any date.

5 daily alarms
The alarms are using an acoustic signal that could remind you of repeating events at a set time. You can also set a time signal that indicates each full hour. This model has five independent alarms for flexible reminders of important appointments/events.

Stopwatch function - 1/100 sek. - 24 hours.
Preliminary time, split time and final time are measured down to 1/100 of a second's accuracy. The measuring capacity is up to 24 hours.

Auto-calendar
The watch automatically adjust for different months different lengths, and for leap years.

12/24-hour timing
The time can be specified either in a 12 hour (AM/PM) or in a 24 hour format.

Solar Energy
A solar cell is the energy source for this watch.

Duplex LCD
This function gives you a better view. On the display, the elements are separated from each other by color. This is made possible by using different color layers on top of others, which present information in a more straightforward manner.

Altimeter (10,000 meters)
A pressure sensor detects changes in the air pressure, and converts the changes to an estimated height position (up to 10,000 meters).

Height gain
This function sums up how many vertical meters that you have gone/done/passed.

Altimeter Memory
Up to 40 sets of data can be saved in memory. These datasets includes the measured height, date and time. Additionally the lowest and highest altitude record, during a measurement, is also saved.

Timers - 1/1 min - 24 hours (with auto repeat)
Useful general information: the countdown timer can provide reminders of special and/or repeating events. The timers can also automatically count back from the defined time. Timers can be set in second intervals, up to 24 hours in advance - so it is very useful for reminding about training/medicine.

Keyboard sounds can be activated/deactivated
The keyboard sound can be deactivated so switching between each function does not make sound. It does not affect alarms, timers or reminders.

Mineral crystal
This, very durable, mineral crystal has improved protection.

Resin strap
Natural resin is an ideal material for straps, because the material is not only very durable but also very flexible.

Indicator for battery power
An indicator shows the current level of the battery.

Water protection: 100 meter (10 bar)
This watch can be worn while swimming. 10 bar/100 meter refers to the pressure in water, at that depth, while motionless... and should not be seen as the depth for wearing the watch..

Condensation - important!
Rapid changes in temperature can cause condensation inside the watch. If you notice moisture beneath the glass, you should immediately go to a watchmaker, who can open and dry the watch. Even if the signs of moisture disappears, by themselves... the moisture will not - and will eventually damage your watch - so, visit a professional and remove it permanently. Even waterproof watches are not protected against condensation, so keep that in mind if you plan to go from very hot to very cold temperatures - like from a hot sauna directly to the snow. If condensation occurs, it very rarely (if ever) depends on manufacturing, so if your watch is damaged by moisture, warranty will probably not cover it (it could be manufacturing issues, but... most likely it will be because of the rapid change of temperature = natural causes).
