LED light
A light diode (light-emitting diode / LED) is used to light up the dial of the watch.
Display flasher
A LED light flashes as soon as an alarm clock, a countdown timer or the hour signal is activated.
Display of day and date
Current day and date is displayed on the dial/screen.
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.
Timer – 1/1 min – 24 timer (with auto repeat)
Useful general information: Countdown hour can provide reminders for special or repeating events. The hours are also counted back automatically from the defined time. The time can be set in second intervals up to 100 hours in advance. Therefore this function is especially useful in for daily intake of medicine/treatment or for interval workout.
Multi-alarm
The watch will remind you of any important event that you set. There are 4 types of alarms:
1. Daily alarm; activated at the same time every day.
2. Date alarm; activated at a certain date.
3. Monthly alarm; activated on the same day each month.
4. Alarm for every day of one month.
Auto calendar
Corrects automatically for months/years with different lengths.
12/24-hour timing
The time can be specified either in a 12 hour (AM/PM) or in a 24 hour format.
Adjustable locking mechanism
The watch has an adjustable locking mechanism, that can be slid to the desired position on the bracelet. The position of the lock can easily be adjusted, and thus fit almost any wrist
Long batterylife
Because of this watch's low energy usage, the battery will last at least 2-3 years.
Stainless steel bracelet
Tough, durable and elegant; a bracelet made of stainless steel gives the watch a classic quality look.
Acrylic glass
This dial is protected by acrylic glass, treated for extra durability.
Water protection: 50 meter (5 bar)
This watch can resist water, but should not be worn while swimming. 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).

Sizes

How is the size of the watch measured?
The diameter
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
