Casio Pro Trek PRW-3500 Watches For 2015 Hands-On

Casio Pro Trek PRW-3500 Watches For 2015 Hands-On Hands-On

Casio Pro Trek PRW-3500T-7

For 2015, Casio introduces yet another new Pro Trek collection watch with the PRW-3500 – offered in a few variations – which predictably build upon the impressive Casio Pro Trek PRW-3000 (reviewed here) from 2014. These fresh “many function” sports watches are a favorite among outdoors enthusiasts and active professionals, and here, they continue a design theme Casio has been carefully refining for many years.

In the age of smartwatches, the Casio Pro Trek models still hold their own, showing that in order to be truly versatile, smartwatches have a long way to catch up before they can beat one of these mega digital watches. The Casio Pro Trek PRW-3000 was important for a number of reasons. One was for having Casio’s third generation Triple Sensor Version 3 system in the quartz movement (which is more accurate, uses less power, and is smaller than before). Second was because for a Pro Trek collection model it was relatively small with a case diameter of just 47mm wide (very small for a Pro Trek).

Casio Pro Trek PRW-3500Y-4

The Casio Pro Trek PRW-3500 uses that same Triple Sensor Version 3 module in the movement, but goes back to the chunkier style, with a wide rotating navigational bezel that Casio Pro Trek customers like. The Casio Pro Trek PRW-3500 has a 53.4mm wide case that is 14.5mm thick and 56.9mm long. Nevertheless, with the resin strap it weighs just 89 grams and offers Casio’s legendary Pro Trek comfort.

A major area of improvement in the PRW-3500 over the PRW-3000 is in water resistance which is back up to 200 meters (a typical Pro-Trek standard) from the PRW-3000’s mere 100 meters of water resistance. For a watch meant to go anywhere, the more “general purpose” PRW-3000 wasn’t quite up to snuff for some recreational diving. Also, rather than having a case produced from “resin and aluminum” (as is the case with the PRW-3000), the Casio Pro Trek PRW-3500’s case is in resin and steel (which adds just a touch of durability for the most demanding of consumers.

Casio Pro Trek PRW-3500Y-1

The Casio Pro Trek PRW-3500 collection is a wonderful all around Pro Trek model with all the features you’d expect, but none of the more exotic Pro Trek functions out there, such as a tide chart or moon phase indicator that you can find on some other models. Like most Pro Trek models, the movement in the Casio Pro Trek PRW-3500 collection offers solar (light) power generation, and a 6 band atomic clock radio signal receiver to update the time automatically in places where the signals are located. Casio’s newest GPS/Atomic clock radio signal hybrid movements, such as in the G-Shock GPW-1000, are not yet available in a Pro Trek collection watch. I think it is only a matter of time before Casio includes this technology in a Pro Trek model.


The list of features and functions contained in the movement of the Casio Pro Trek PRW-3500 is very long but should be familiar to anyone who has had a Pro Trek model in the recent past. I personally use functions such as the sunrise/sunset time indicator, the chronograph, and world time indicator the most, in addition to basic time telling features.

Casio Pro Trek PRW-S3500 “Real Material Series”

Of course what makes the Casio Pro Trek PRW-3500 a “real” Pro Trek is the triple sensor functionality which offers (at the touch of a button on the side of the case) a compass, barometer, altimeter, and thermometer. Each of these functions offer vastly improved performance compared to any Pro Trek model that does not have the Triple Senor Version 3 module in the movement.

As I am writing about the Casio Pro Trek PRW-3500 I am asking myself, “how could Casio make this a cool smartwatch?” I think that it is possible for Casio to add useful smartwatch functionality, while at the same time, allowing a Pro Trek to maintain its reliable “go anywhere” spirit that it gets from not needing to have its time set or needing a charge.

A smart Pro Trek watch would most certainly need to have a GPS signal receiver and make the best use possible out of its solar power system so that you’ll never need to charge a battery. It might also be nice to combine the sensors on the watch with those on a phone to come up with some interesting information on that lovely, large, legible dial. Here’s me hoping and wishing that Casio’s engineers can keep the Pro Trek amazing in the future while also adding smartwatch features that can be optionally used with it.

    the best watches for true use!

  • Fraser Petrick

    I have a G-Shock and love it; but for a geriatric dinosaur such as myself it’s too darn confusing tryin’ to adjust the thing to the right time and date. Furthermore, it’s humiliating when I have to ask our home IT serviceman (age 18) to adjust it when he comes for the annual oil-lube&filter on our desk tops. Might this Pro-Trek be idiot proof for a grandfather of 1;  2 in late May?

  • thornwood36

    Stick it on and lets go…………..

  • Phoenikz

    I’m just a father of a 16 month old (young – middle-aged), and I really can’t give a hoot about learning how to set these things. I use a cheap Casio (tough solar) for my gym – I look at the time – That is all. Despite it’s laps, time zones. stop-watches, et al., it’s all a joke when we carry a smart phone in the pocket … And there’s this –  Like most people – I don’t give a shee’at about these details when working-out.

    PS: Casio – If I want ‘World Time’ when travelling, I wear a proper watch… for anything else I look at my phone  –  (soweee).

  • GaryK30

    Fraser Petrick You might try a radio-controlled G-Shock or Protrek like the PRW-3500 profiled here, if you live in an area that supports this capability. This way the watch will set itself. I have four radio-controlled Casios (three G-Shocks and one Pathfinder/Protrek). I’d say they successfully set themselves overnight at least 95% of the time. I find radio control and solar charging to be useful features.

  • DG Cayse

    Phoenikz Reasonable comment that I think reflects the thinking of about 98% of people.
    I like the G-Shock models and I would like to see a “trimmed” down offering of this technology in a 45mm size.

  • DG Cayse

    Fraser Petrick Congrats on the new addition. Best to Mom and Child.

  • Aghast!  Yet another article about a smartwatch?   Wait…

  • Phoenikz A watch for glancing at the time is the vast majority of my timekeeping needs also and as you pointed out, a cell phone pretty much does the rest. While my watches have date indications, at my age (62), I can’t read it unless I have my reading glasses on  – the time of day I can see just fine without optical assistance. At my desk the PC shows the time. In the car, it has the time usually in 3 places at once. But when walking around, a watch on my wrist is exactly what I need. Plus as we all know, your choice of watch is a personal statement (of some sort). I’ve had Casios and other multi-function quartz watches over the years and they are ALL A PAIN IN THE ASS to set-up. I’m beginning to think Breitling with their “Connect” watch and phone app that sets the watch may be the way to go for quartz watches in the future. Cheers.

  • In talking about what Casio might do to make a smarter watch for the G-Shock series, how about a simple connection (Bluetooth or even better, NFC) that syncs the time on the watch from the phone (which we assume has accurate time from the phone network). No need for atomic or GPS receivers in this case. And the watch could transmit back the battery charge level. Casio would be my choice for a solar powered “smarter” watch. But it would be nice if not every reference had a robot face.

  • Baerli Baer

    MarkCarson The Casio Manaslu (prx 7000t) is in comparison a much smarter/dressier Protrek, (though still quite far from being smart/dressy!).

  • Baerli Baer

    I love my protrek (prw-1300y). It’s perfect for when I’m
    feeling a little less dressy and my go to watch for many outdoor activities such
    as walking, hiking, backpacking (holidays) and skiing (use a Garmin for cycing
    and running to records the ride/HR etc). It can take a good bash, accurate
    time, no worries about battery drainage and looks like it’s good for the job. 

    neat to be able quickly find out your altitude when skiing or hiking and reassuring
    to have a compass for such activities (which does get used). The barometer I
    never use, and the temperature function is only good for telling you the temp
    of your wrist!

    Like the look of these new models, though no so keen on the bigger size. Mine already looks huge on me (athough i do have tiny wrists!).

  • I_G

    I wonder what “TOUGH SOLAR” means. Do the watch manhandle the sunshine? Is there a G rated SOFT version?

  • Tough movement (resistant to shock, etc) and solar powered. They’ve been using that term for a long time: where have you been?

  • I know that the sensors in the pro treks have gotten much better over the last few years, but I am loathe to replace my ever-trusty pag-240. They’ve never made one as user friendly since: the large display with duplex lcd is simply unrivaled, and I actually put mine to the test. It has never let me down. If this 3500 only had the duplex screen and functionality, I’d go out and buy one today.
    Casio, WTF?

  • shinytoys

    Pro-Trek, my everyday wear piece.

  • shinytoys

    MarkCarson Casio has some nice looking analog pieces available, check them out:)

  • Shawnnny

    I have a G-Shock GW3000 with Tough Solar. I bought it for mountain bike riding. Unfortunately, I guess it’s not tough enough. Because when I get back from a ride the time and everything else is all wrong and it’s a pain to manually set it and it only gets a signal maybe once a week. Other than that, I love the watch. It seems to make it through everything else.

  • Capelander Guy

    I have the Pro Trek PRG550-1A1, which is the analog model that also has a
    small digital display.  It has all the bells and whistles (barometer,
    altimeter, temperature, world time, Pac Man) while also retaining some
    of the traditional analog look and feel.  I agree with other posters
    here that with all of the functionality, it takes an eternity, plus an
    act of congress, to set up.  But it does have a Daylight Savings Time
    on/off toggle, which means that, theoretically, once you set it up, you
    don’t have to go through the process again.  It also looks presentable
    on an olive nato strap.  To me, a watch without hands is like a car
    without wheels, so the analog model is a good option for a
    beater/outdoor watch that retains some of the traditional analog look.

  • shinytoys

    I don’t find them difficult to set up, keep the owners manual handy and you’ll find it’s easy with a little practice.

  • I_G

    SuperStrapper I’ve been where a ‘TOUGH” title looks stupid on a watch. What’s the next version, “BADASS”?

  • GaryK30

    SuperStrapper I agree regarding the duplex display. I have a PAW-2000 with this feature, and I think it’s very useful.

  • thornwood36

    That’s one ugly lookin’ watch

  • Frank Wulfers

    Not sure why there is so much complaining in setting up a watch like this.  I have both the the orange/black and silver/black version of the PRW3500 purchased in the US and both were already set up with DST on auto, timezone set to NYC and measurements in ft, F and in hg.  It even synced with the atomic clock while it was in the box being delivered to me.  There was nothing to set up at all and it will always be accurate.  Reading the manual for 10 minutes is ll you need to use most features and make a few setting changes if wanted.

    The reviews shows the 3500Y-4 as being red but it’s orange.  Not reddish orange but Coast Gueard orange.  I think this is the nicest quality Pro Trek so far (also have a PRG550, PRW3500, PAW2000).  My review can be found here if interested:

  • Jimxxx

    thornwood36 but in a cool way.

  • I like how they made the PRW3000 smaller but I don’t like the bezel on this one The PAG240 is still one of the best Pro Treks and it’ll be interesting to see if they upgrade it soon or if there will be any new models with a duplex LCD.

    • keith

      PRW-2500 is the best of the series IMO.
