Casio ProTrek PRG-550-2ER
Auto LED Light
A LED (light-emitting diode is used to light up the front of the watch. The watch also has an Auto Light Switch, that lights up the display when the dial is angled towards the face.
Resistant to cold
This watch can withstand temperatures as cold as -10° C.
Solar Energy
A solar cell is the energy source for this watch.
Digital compass
A built-in direction sensor finds the magnetic North Pole.
10,000 m altimeter
A pressure sensor detects changes in the air pressure, and converts that data into altitude... up to 10,000 feet above sea level.
Altitude
This function sums up how many vertical meters, for example, you have climbed.
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.
World time
The largest cities in the world are pre-programmed in this watch, so select current city (or the one closest to you - in the same time zone) and the watch will automatically show the correct time.
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.
Stopwatch function - 1/100 sek. - 60 min.
Preliminary time, split time and final time are measured down to 1/100 of a second. The measuring capacity is up to 60 minutes.
Timers - 1/1 min - 1 hour
Useful general information: the countdown timer can provide reminders of special and/or repeating events, and it can be set in second intervals, of up to 1 hour in advance. Therefore the function is extra useful with exercise/intake of medicin.
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.
Keyboard sounds on/off
The keyboard sound can be deactivated. This does not affect any other functions of the watch, like alarms, timers, reminders.
Auto calendar
Corrects automatically for months/years with different lengths.
12/24-hour clock
The time can be presented in either 12 or 24 hour format.
Mineral crystal
This, very durable, mineral crystal has improved protection.
Resin case
Resin strap
Natural resin is an ideal material for straps, as the material is characterized by being very durable as well as 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).

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
