    • Casio quality is unmatched for its class.
Color: Silver Style: PRW-3500T-7CR
Love this watch. Does everything I want it to do. The bracelet was difficult to adjust because I didn't know how to use a link tool, but I finally got it perfectly fitted to my wrist. Setup was rather steep on the learning curve for me, but I kept at it until I got it set up perfectly. The case and bracelet are super tough, the sync function works consistently, and the Barometer works perfectly. The power reserve indicator has shown Full the whole time I've owned it because I wear it every day, so it's exposed to light all the time. To get an accurate Temperature reading, however, one must take the watch off the wrist to allow it to shed any residual body heat from the device. The Compass and Altitude functions work just right for my needs and were easily adjusted/calibrated. The Sunrise/Sunset feature is good to have. The four time alarm is a bit on the quiet side for me, as I am a heavy sleeper, and there is a snooze function as well. The Stopwatch has a "split" function and measures down to 1/100th second. The Countdown timer is very handy. The backlight is very even across the watchface. If desired, the Auto Light can be set to one or three seconds and it activates only when the environment is dark. With just a flick of the wrist you can activate the backlight or press the light switch to turn it on manually. The Hourly Signal is handy. Once set up and calibrated, the watch is essentially on "auto-pilot." With use, the watch becomes easier to operate. The fit and finish of the watch is stunningly beautiful, tough and all business. The glass face has no scratches and the case and bracelet are still in perfect condition after a year of use. For the price, it stands out as a really great value. If you have the means, I highly recommend picking one up. ... show more

    • Highly functional tough watch
Color: Silver Style: PRW-3500T-7CR
This watch has all the features I was looking for and a lightweight titanium band. It's a nice looking watch, but I bought it more for its functions (thermometer, barometer, altimeter, sunrise and sunset times, auto time set, etc.) than cosmetics. I've had the watch for about 3 weeks and have worn it daily. It's a bit larger than my previous Casio Pathfinder and felt top heavy at first, due to the heavy body and light band. The band is comfortable and took about a week to "stretch" out and become comfortable. A word of caution: if you adjust the band yourself, as I did, be very careful with the spring-loaded pins in the clasp. I suggest doing the work in a box to contain any falling or springing parts...or just take it to a jeweler. The watch face is very clear and has excellent visibility both in day and at night when lit. I don't have much use for the rotating bezel, so I think they could have made this lower profile - it really stands out and I foresee it getting dinged up - at least it's metal. The band also seems to be more prone to scuffing than other watches I've owned, but so far this is pretty minor. The big improvement in the band is where it attaches to the watch body. Casio used beefy pins and a rubber pad to really support this weak spot where several of my older watches failed. All in all, an excellent watch that seems like it will last many years. ... show more

    • I really like this watch
Color: Silver Style: PRW-3500T-7CR
I really like this watch. I have always wanted a watch like this and finally pulled the trigger and got this one. This watch looks very nice. The numbers are very easy to see and the time is very accurate. The main features (Compass, Barometer, Temperature, Altimeter), work great. Although when taking a temperature reading on your wrist, it will not be accurate. If you are out and about in the elements of mother nature, having the thermometer close to you, or on your skin means that you can keep an eye on your temperature and avoid large changes in your body temperature due to the weather, if you want an accurate temperature in an the area you are at, you will want to remove the watch and let it sit for about 5 minutes and then take your reading. The compass and altimeter seems to be spot on, after I calibrated them (which is very easy to do). The Barometer is fairly accurate as well, it can alert you when the pressure changes significantly. Sunrise and Sunset data is also accurate, however you will want to adjust your latitude and longitude in order for that to be accurate, or else it will just use the sunrise and sunset data based off of the timezone you are on, adjusting the latitude and longitude is very easy to do. I did need to adjust the band, I took two links out, fairly easy to do yourself (I thought it was). When taking the links out, there is a small collar that goes around the pins, very easy to miss. If you put the pins back in without the collar, the pins will slide back out. So be sure the pins get put back in with the collar when taking the links out. The alarm, stopwatch, and timer work great, so does the LED back light. And I like the fact that I never need a battery, it charges via any light source. There is a power saving feature for this watch, when enabled it will extend the battery life if left in storage by shutting the display off and it will also shut the display off at night when it senses it is not in use, I disabled it for the time being because I do not plan on taking this watch off and storing it anytime soon. This watch looks good, feels good on the wrist, and ready for an adventure when you leave the office. ... show more

OK let me say i have a HUGE collection of casio watches ranging from the 1980s to present. When this thing came in, i hated how ugly i thought it was. Didn't fit the bill for me style. So i sent it back. Well.... biggest mistake ever. Ended up buying it again 3 days later because let's face it, here's the truth. This thing has atomic time keeping. Always on the dot of exact time and you can't beat that. The back light on this thing is unlike any casio I've owned. Man is it powerful! With the lights turned off in my room it literally illuminates the entire room and i love that POWER! The display is clear as day. I can look at it at any angle and know what time it is. Clearer than any casio i own. Now the barometer is super accurate. It let's me know when a storm is coming and when the weather is good. A fantastic barometer with those version 3 sensors everyone wants. The altimeter is great. I'm a skydiver and i take this thing up in the plane with me and my lord! I press the altimeter button and it is dead on with my main altimeter as we climb up. The compass is accurate but the function i use the least. And the 200 meter water resistance you just can't beat. If I'm not in the sky, during the summer I'm in the ocean doing some body surfing and i cannot wait to see how this thing does in the ocean or the pool this year. I like that its titanium as it adds some character and stand out to other people's apple watches and what not. Overall great watch, definately on the expensive side but great watch! ... show more

    • A very capable, if bulky, coated *RESIN* case, ProTrek, with disappointingly WEAK alarms (across all functions)
Color: Silver Style: PRW-3500T-7CR
NB:: THE CASE FOR THIS WATCH, AS SHIPPED IN Q1 2017, IS A HARD-COATED (EPOXY?) RESIN MATERIAL. THE CASE IS *NOT* MADE OF TITANIUM, THE CASE BACK IS STAINLESS STEEL. ONLY THE WRISTBAND IS TITANIUM. That caveat aside, my ProTrek PRW-3500T-7CR (Module 3134) is an emergency replacement for a tragically and irretrievably lost PathFinder PAG70-T (Module 2872). [While the PAG70-T has no Atomic Clock sync capabilities, what it has, in spades, is a very sharp looking, "dressy" appearance, as great looking with any suit as with any wilderness survival loadout. The PAG70-T's case is Titanium-clad-over-resin, with a stainless steel back and titanium wristband; no rotating outer bezel (which I have no need for), At the time of loss, my PAG70-T was still going as strong as Day One on it's original CTL1616 solar recharged battery. Even though the built-in calendar was due to expire in 2039, I was only going to cross that bridge in 2040, The countdown timer has final 1min, 50sec, 40sec, 30sec, 20sec, 10sec then 1sec interval warning beeps before the final countdown chime. If left uncancelled, the countdown timer would automatically lap and repeat the original countdown. I found that to be an unbelievably useful countdown feature. All PAG70-T alarms are clearly audible across a reasonably quite room and/or under a jacket sleeve. I seriously miss that PAG70-T. For all that I put it through, not a single scratch or nick anywhere on it.] On paper, the PRW-3500T-7CR out-classes the PAG70-T's specs. Atomic clock sync (which works every time for me, on a daily basis, some 2000kM from Fort Collins, with a "L1" signal strength, as reported by the watch). Built-in calendar through 2099. 200M static water resistance. So-called "V3" triple sensors. Etc. But I'm still getting used to the PRW-3500T-7CR, and I'm not quite as impressed with it as I hoped to be. The alarms on the PRW-3500T-7CR are surprisingly and disappointingly WEAK. A covering jacket or other thick sleeve is more than enough to smother these weak alarms. The countdown timer has no final minute intermediate chimes and cannot be set to auto-lap when left uncancelled. Alarm durations are 10 seconds, at best, and are not configurable for longer notifications. One of the five daily alarms is a "snooze" alarm that repeats at intervals for 30 minutes. But what good is a snooze alarm if you can't hear it? I'm forced for the time being to wear my PRW-3500T-7CR on my right wrist. For some reason, after several reference temperature calibrations, the V3 thermometer gives closer to actual room temperature readings, while uncovered wrist worn, than the PAG70-T; typically less than 5 degrees Farenheit warmer than ambient air temp. Sleeve cover will obviously skew wrist worn temperatures higher than ambient room, due to confined body heat.. The V3 compass is very accurate when compared with GPS readings and the PRW-3500T-7CR compass can be calibrated (by 1 degree increments) for declination (the PAG70-T has no compensation for declination). The V3 barometer is reasonably accurate following a 12-day series of daily calibration check/settings at constant reference altitude. The V3 altimeter is surprisingly and sometimes wildly inaccurate when compared with GPS, even more so than the older PAG70-T. I am seriously doubting that any amount of altimeter calibration is going to achieve more accurate readings, but I am optimistically still continuing with once daily calibration checks at reference altitude. Sunrise and sunset times are highly accurate, once longitude and latitude are manually and correctly entered into Settings. This is not the same as merely setting the Time Zone, unless you happen to actually be located in one of the preset Time Zone cities. My PRW-3500T-7CR illuminates very evenly across its face in a dark room, even though there is only a single light source, eminating from the left side of the watch face, If your's doesn't illuminate evenly across the entire watch face, then you may have a lemon worthy of prompt return/replacement. The PRW-3500T-7CR is significantly larger than the PAG70-T, which may present problems for smaller wrist sizes. I had to remove four (4) wristband links, two on each side of the locking clasp, in order to achieve a functionally comfortable fit. WRISTBAND ADJUSTMENT NB:: Each link pin of the titanium wrist band is retained in place by a single 1mm diameter split "clinch barrel ring" that too readily slips in and out of the one "receiver" side of the short prong of each link (when disassembled). When fully and properly assembled, the link pin passes through this tight clinch barrel ring and the clinch barrel ring prevents the link pin from sliding out of the wristband (preventing band failure) by sheer friction with the link pin. What is not immediately apparent to an inattentive observer is that the link pin also holds the clinch barrel ring in its proper place, between wrist band links. Once a wristband link pin is removed, THAT CLINCH BARREL RING WILL *IMMEDIATELY* FALL OUT OF PLACE AND CAN BE VERY EASILY LOST. I know of absolutely no source for replacement clinch barrel rings for this wristband. When I disassembled my wrist band, I did so over a reasonably large disassembly tray (18inx18in), with a surrounding raised lip edge (1") and a non-bounce white tray liner. As each link pin was carefully removed (observing the directional arrows engraved on the wrist-side of each removable lnk), using only the force absolutely necessary and a proper pin removal tool, I could see the TINY clinch barrel ring fall onto the tray liner (and then set it aside for safekeeping). When reassembling shortened links, I had to use needle tip tweezers to place the clinch barrel ring back into the RECEIVER SIDE of the stub link, oriented UPWARDS toward me, so that *gravity* would hold it temporarily in place. Then I used a positionable vice grip to hold the two links together, while I reinserted the link pin, through the links and the clinch barrel ring. The vice grip temporarily held the links together in-place, such that I could rotate the band, with the clinch ring now facing downward, as I gently drove the link pin back into place from above. This was the least tricky and most first-try successful way to adjust the length of the wrist band. Should you decide to adjust your own wrist band, whatever you do, do not lose the clinch barrel rings. Without them, the link pins will fall out and you will have band failure. The only durable and reasonable kludge for a lost clinch barrel ring would be "red"-grade (permanent) ThreadLock on BOTH sides of a fully inserted link pin. As always, Casio Customer Service is DISMAL at best. If you get a lemon, replace it with the seller right away for one that works 100% as advertised. Casio Customer Service depends on their products not failing -- and for the most part, when a Casio watch works AOK from Day One, it will continue to do so until you lose it or destroy it. Casio Customer Service has never ever "been there for me" and I have learned that lesson only too well. ... show more

    • Love this watch.
Color: Silver Style: PRW-3500T-7CR
These pathfinder watches are the most durable around. I destroy most other watches. This is the third Pathfinder I have owned. The last one started losing pixels after five years. I need reading glasses these days to see fine print. The display is easy to read for basic functions.I cannot read the battery levels without reading glasses. The LCD display can be read easily with polarized sunglasses. A feature not all displays have. The light is not on long enough but it is a cool blueish color. The one light button at the bottom of the is an improvement over the older two buttons. The compass is decent. The solar charger makes for infrequent battery changes in previous versions. I expect at least a couple of years out of this battery. The WWV time correction makes for no adjusting. That is good for us "fall back" procrastinators. Multiple time zone display I can see what time it is UTC. Sailboat racing demands a countdown timer. This watch has one but I would like to have a minute roundup and round down feature on the countdown timer. I like that the countdown timer also displays current time as well as the timer. I see a 1 minute difference in sunrise sunset despite entering the longitude. The buttons were better on the older model. These have just slightly harsher edges. I do not really care for the button guards. It has a titanium band. Oh did I say titanium band. The band is easy to clean. Just take it in the shower and its cleaner than my mouth.I have had resin bands that feel icky and get sweat jelly in adjustment holes. I adjusted the links myself. The pins did try to bolt for freedom and fell out after I re-sized the band. The solution was simple, just take a pair of pliers and bend the pin ever so slightly and those pins are pinned-in semi permanently. Overall this is the best watch I have owned. ... show more

    • Reliable and accurate
Color: Silver Style: PRW-3500T-7CR
Bought this 6 months ago, upgrading from a PRW-3000T (which is still running fine after 11 years of daily wear). This watch delivers the reliability, functionality and durability you'd expect from a Pro-Trek, with the lightweight Titanium strap that makes it comfortable to wear. It's a great travelling watch as the world-time mode is very easy to use. What the 3500T adds compared to the 3000T is: - More accurate. When it didn't auto-sync with atomic time (because it was away from a window) it only lost 4-5 seconds per month (compared to 15 secs/month with the 3000T) - More comfortable on the wrist with small curved supports on the base. - Sunrise/sunset times (which is more useful for me than the tidal display on the 3000T). - Sharper look with the improved compass dial. The stopwatch is 1/10sec compared to the 1/100sec of the 3000T. Some notes on using it: - In Washington I need to put it on an East-facing window sill to sync with atomic time. - Don't try and adjust the Titanium strap unless you know what you're doing. It's worth paying a jeweler a few dollars to adjust it properly. Other than that it's hard to go wrong with this watch. It just keeps running. ... show more
