Time signal
This watch can be set to give a signal for every passed hour.

12/24-hour clock
The time can be presented in either 12 or 24 hour format.

Stopwatch function - 1/1000 sec. - 100 hours.
Intermediate and final time are measured down to 1/1000 of a second! The watch's measuring capacity is up to 100 hours, and a signal indicates when the function is started/stopped.

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.

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.

Snooze function
You can pause the alarm, and it will be reactivated after a few minutes.

Speedometer

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

Long batterylife
The battery in this watch will last at least 2 years, because the watch use less energy.

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

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

Water protection: 200 meter (20 bar)
This watch can be worn while swimming/snorkeling (near the surface). The value 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).
