The Casio ProTrek PRW2500-1 multifunction watch is a high-performance instrument that keeps time via the accurate Atomic Clock and reliably draws its power from the sun.


Lining and Layers:

  • Duplex LCD layout provides a 2-layer display for clear information at an easy glance when you're on the go


  • Thermometer ranges from 14 to 140°F (-10 to 60°C) measured in 0.2°F increments (0.1°C)
  • Watch automatically receives Atomic Clock time calibration signals in the U.S., England, Germany and Japan for incredibly accurate timekeeping
  • Digital compass displays current heading; reports bearing in 1° increments
  • 200m water resistance helps protect the watch while rafting, swimming or other activities that may involve strong water pressure
  • 1/100-second stopwatch measures elapsed time, split time and first- and second-place times
  • Altimeter tracks elevation gain/loss from -2,300 to 32,800 ft. (-700 to 10,000m); stores up to 40 records of high/low altitude, cumulative ascent/descent and date/month/time
  • Triple sensors enable easy, 1-touch operation of an altimeter/barometer, compass and thermometer
  • Numerical/trend graph data and distinctive arrow icons indicate barometric pressure patterns; barometer tracks atmospheric pressure from 260 to 1,100 hPa (7.68 to 32.49 inHg)

Excellent Travel/Adventure Watch

I purchased the watch specifically so I'd have a reliable Travel/Adventure watch. I did a lot of research and on various Casio G-Shock watches and looked into some other brands: Timex, Suunto, Armitron. None of the others have the features packed into them for the price. So far it is an excellent watch and though it takes time getting to know how to operate it, if you are a detail-oriented type individual this watch is excellent.

My biggest critiques:
• The Compass bezel must be like aluminum because it scratches really easy.
• Unlike Timex, Casio doesn't have a lighting feature that stays on; so when you cycle through the features, the light turns off after 3 seconds leaving you lost on where you are at.
• The Alarm is only good between 1min-60min. Why they do not let it go from seconds to hours is beyond me...

All in all, the watch is reliable and accurate. The barometer, thermometer and altimeter are pretty accurate and deviate very little and do not require recalibration often. Time will tell how durable the watch really is and how reliable it will be to keep going.

I love the watch, but a little "screwy"

I use this when hiking and traveling the world for work. I love it for keeping track of time in different locations and the compass provides comfort when out walking around a new town. My only complaint is the screws and bar holding the band on. The top set is loose. It does not come off, but it rattles a bit. I took it back to the store to trade it in only to find that another new one had the same issue. I kept my original watch. The screws are tight in the bar, but it seems to be a just a bit too long. Maybe for thermal expansion/contraction? It has not had any issues and I really like it, I just wish the screws/bar didn't rattle.

Amazing watch!!!

I bought this watch because I moved to Guam and knew that I would be scuba diving, snorkeling, and spending time in the ocean. I love the tide feature, it is very accurate. The barometer, compass, and altimeter work great! If you spend time in the outdoors hiking or in the water it is the watch for you. I love this watch and was torn between the ProTrek and the glad I went with the ProTrek. My only complaint and it's nothing major is that it is a little heavy. However, for what you get it is expected. Best watch I have every owned!

So far so good

I really vacillated between this watch and the Suunto, and spent some time with both models. I decided to go for this model predominantly because it seemed to be more bullet-proof, plus I liked the fact that it does have the tidal features (which I'll put to use in my kayaking expeditions). So far I've been impressed with the watch- looks good, packed full of features, feels pretty light on my wrist, and just feels solid and well built. Time will tell how all these features actually pan out in extreme conditions, so an update might be forthcoming.

Great Watch for Hiking

I use the watch mainly as an altimeter and Barometer. This thing has everything. It works great as long as you calibrate it before you will be needing it as an altimeter or barometer. It will only take you about a minute to calibrate based on your current location and given information (i.e. the elevation of the base of a mountain climb). the compass is also very accurate and has been able to help when my GPS shuts down, this watch is solar powered and never shuts down.

Excellent Product

I use it to keep track of the altitude when skiing. I have to get used to the fact that barometric changes are affecting the altitude reading, so it has to be corrected when at a known altitude(like the ski base). I like having the time accurately updated every night. The temperature readings unfortunately are affected by my body temperature. It never seems to need to be recharged, relying on ambient light. So far it appears to be an excellent product at a reasonable price.

ProTrek PRW2500-1

This is a great multi-sensor watch. My only gripe is the low-res of the tide graph - only two hour blocks. And the band is wearing in the grommet hole that I buckle - minor though.
Other than that this is a great watch. I wear it everyday on land and in the ocean. It is very comfortable and the multi-sensors are real handy.

Great so far.

Complicated but does what it says.

Great watch, display is a little crowded

Hard to beat a Casio, loved the watch but returned it for a casio pag 240, I could not read the time without my glasses,,,, the tide displAy takes up too much of the screen for me. Keep in mind the tide will only work for one location, so not too much value there do the display realestate.

Great watch, but just too crowded for me.

Nightmare to calibrate...

The watch performs us it should, but is a total pain to calibrate.
