Stopwatch function - 1/100 sek. - 24 hours.

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

This, very durable, mineral crystal has improved protection.
Natural resin is an ideal material for straps, because the material is not only very durable but also very flexible.
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).

How is the size of the watch measured?
The common term is diameter, but since not all watches have circular watch cases, the diameter is actually the width measured from left to right. Note that some manufacturers include the crown (to set the clock) and the buttons when measuring the width, but we try to standardize all the watches by not including the crown as part of the measured width.
The thickness - or height of the watch in profile - is indicated by measuring the watch from top to bottom as illustrated below. By comparison, a 1-euro coin is 2.33 millimeters thick.
One usually defines the watches with these numbers:
Slim: 4-6 millimeter
Normal: 6-12 millimeter
Big: 12-14 millimeter
Oversize: 14-18 millimeter
