Casio Pro-Treck What is this Watch about

pwr6000-Caartoon-004.png pwr6000-scene-003.jpg Casio's Pro-trek line of watches are outdoor watches. It would not be far of the thruth to claim that almost no one who buys this watch ever would need the out-door functions of this watch only once. Even if you are on doing serous outdoor activity there are far better internet and GPS based tools to get actual infomation enroute. Only people who are far of civilasation for a prolonged time, like en excurstion or on an ... would benefit from this functions.
So let me first review the regukar function like the readability radio time syncronisation, worldtime before review the out door funtions of the watch.


For day trips most of its functions are available by other means, like Internet combined with a smartphone of GPD Navigator. You get Weather forecasts, Sun-Rise, Sunset Data. RainRadar, GPS navigation and maps for your cell phone
But these are high power devices that depend on a possibility to recharge often as well as on mobile telecommunication networks. Thus Many of the functions make only sense if you are on long term outdoor trips away from civilization. For office workers only Atomic Time Receiver, World-Time, Stopwatch and Timer remain useful. Let have a closer look.

What makes any watch useful?


pwr6000-scene-001.jpg pwr6000-scene-002.jpg
The Casio Pro-trek PRW-6000Y has certainly a lot of features. But are they useful?
Atomic-Radio Time
The watch keeps precise time from 6 atomic watches worldwide if in Range. If you are living in range of one of them, like me, you have always the precise time and automatic DST changes at your wrist. This feature works very well and gets daily updates of the time.

World-time
Useful for people that travel a lot between timezones. The key feature is the Swap Home and World time. You can select from 29 cities. The watch second hand point for a few seconds to the timezone that is writen as 3 letter airport code in tiny letters after which the second hand returns to show the seconds. The home time is shown on the digital display without timezone, just abbr. as "HT". The whole implementation is so useless, you don't know if the world time is p.m. or a.m. or which timezone it is, if it is DST or not, what is the aitprot abrev. mean of if which airport is in the same timezone. You even have to know if world time is DST or not. The best would be it world time would be on the digital display along with timezone.

Stopwatch
Relative easy to operate and useful if you often time events You need this mode to access quickly and therefor it you be the first mode in sequence instead of Barometer mode.:q

Hour
Another way to quickly change the time after a plane trip the watch has a posibility change the watch in full ours in time mode. But when doing so the watch will not keep the minutes and seconds and change the hours it will reset the seconfs to zero and advance the minutes by one whihc make it totaly useless.

Altimeter
Only useful if you do you do mountaineering or piloting unpresurized planes; Cumulative Assent and descend are very useful to see what you have archived. It is easy to set the altitude.

Compass
Only useful if you do outdoor activities. You can precisely adjust a map with the second hand pointing to north

Barometer
Only useful if you do outdoor activities on flat terrain. In mountain terrain the air pressure changes
much more with the altitude then with weather. Most useful are weather trends to predict oncoming weather.
Thermometer
It actually measures a mixture of Body and ambient temperature and is therefor useless. The manual suggest to put it 20-30 min to get a proper reading. It can only measure temperatures up to -10 °C which prevents you form measure winter .

Recording 30 data points
It is so complicated to do this operation that this feature is useless. You would more likely use a GPS for tracking.

Timer
Useless. Only maximum of 60 min is possible and it quickly goes in auto mode which makes it useless.

Light
Phos.. ; Auto LED switches light on when holding 45° to your vertical - Great feature which works.

Ergonomics:
Light and well readable dial and relatively easy to operate.

The user-interface of the PRW-6000y-1ER has a certain enough consistent to provide some useful functions but still leaves a lot to desire. For example when you are in stopwatch mode you cannot just press COMP or ALT to get into compass or altitude mode because this buttons are used by the stopwatch. You first have to return to time mode to use COMP or ALT.
There are modes like Stopwatch and Compass you want to enter rather quickly and there are modes that like ALT, BARO, and World-time or TEMP which are more relaxed


Button press should trigger light if dark

Barometric Pressure and Altitude


pwr6000-Baro-Scale-002.png
Atmospheric pressure is the force per unit area exerted on a surface caused by the weight of air above the measurement point as illustrated by figure. On average, a column of air one square centimeter in cross-section, measured from sea level to the top of the atmosphere, has a mass of about 1.03 kg and weight of about 10.1 N (2.28 lbf) equal to or 1013.25 hectopascals. Equivalent to 760 mmHg (torr), 29.92 inHg, 14.696 psi.
This pressure changes either by altitude or by the change in weather.

Average sea-level pressure is 101.325 kPa (1013.25 hPa or mbar)

Altitude

We laearnd that there column of air is about 1.03 kg equal to or 1013.25 hPa at sea level or 29.92 inHg. As air gets thinner this preasure quickly drops. At
     0m  there is 1013 hPa
   500m  there is  960 hPa
   600m  there is  950 hPa
  1500m  there is  859 hPa which is 84%
  2500m  there is  760 hPa which is 75%
  4000m  there is  630 hPa whihc is 63%

TAs a consequnsce you ger 25% less oxcygen ad 2500m or 37% less oxygen at 4000m.






Reset Altitude Differential



Set Reference Altitude

pwr6000-scene-005.jpg
The problem is altitude indication changes weather related pressure changes showing a false indication. You are generally advised to set altitude at reference signs there are often or after map references at the begin of the trip. In Switzerland there are many signs along the marked hiking pathes which state the reference altitude.



Auto Record Altitude related

When in Altitude mode the watch records
Basically every 15 m of altitude difference is recorded

Set Altitude Differential to 1000 m Mode

To delete all Altitude Records and therefore reset them before an hike do


Weather

Average sea-level pressure is 101.325 kPa (1013.25 hPa or mbar) The air pressure changes at a location according to changes in the weather situation
 1086 hPa (32.08 inHg): Highest Ever Recorded
 1030 hPa (30.42 inHg): Strong High Pressure System
 1013 hPa (29.92 inHg): Average Sea Level Pressure
 1000 hPa (29.54 inHg): Typical Low Pressure System
  980 hPa (28.95 inHg): Hurricane 
  870 hPa (25.70 inHg): Lowest Ever Recorded

At higher altitude the respective actual air pressure is lower. For reason of comparability this pressure has to be adjusted to the altitude of sea level.
This is the atmospheric pressure normally given in weather reports on radio, television, and newspapers. When barometers in the home are set to match the local weather reports, they measure pressure adjusted to sea level, not the actual local atmospheric pressure.
This is fine for barometers at home but quite changing for a barometer on a watch that changes location all the time. For this reason barometric measurements, including tendency graphs, on your watch only works when you are at flat terrain.
Fore example when you hike from 1500 m to 2600 m the pressure lowers about 100 hPa while a Weather change good to bad or bad to good weather typical only changes the pressure 10 hPa.

Tough Solar - Solar Charging

There are less power hungry functions like time keeping and more power hungry function like using the compass, stopwatch, barmeter or altimeter.
According to the Casio brochure the new Version 3 Tripple Sensor using only 1/7 of the energy for the pressure sensor and 1/10 for the direction sensor.
Pro-trek watches are Solar that are charged with solar power. This keeps the watch more power hungry function operating on excursions away of civilization.
To compensate for average daily usage my PWR-6000 needs :
   8 min bright sunlight (50000 Lux) 
  30 min sunlight through a window (10000 Lux)
  48 min daylight trough a window on a cloudy day
 480 min (8 hours) indoor fluorescent light (500 Lux) 

According to the Casio's Operation Guide 5365. It is to note that this is just for compensating daily usage and not to fully charge an empty watch battery.
The following shows how much exposure to light is required to recharge the battery by the amount used by one display light operation.
 Approximately 5 minutes exposure to bright sunlight coming in through a window
 Approximately 50 minutes exposure to indoor fluorescent light


Even here in far north where it is dark most part of the day in winter it charges well so far.

World Time and Time Keeping


Configure the World Time on the PWR-6000 line of Watch


After the that watch hands show the world time and the display shows the local time.

Handling

Using the Pro-Trek in salty sea water

Your PWR-6000 is waterproof up to 10 m. According the Casio's FAQ below whenever your watch is exposed to sea water or mud, rinse it off with clean fresh water.
