Casio PRW3500 Series | Pro Trek | 100M WR | Compass | Alt/Baro-Thermo | Tough Solar Power | Atomic Timekeeping | 1-100 SEC Stopwatch | Countdown Timer | World Time

Another amazing Casio product. Never had a pathfinder before and wanted one, however the current available one being sold by 3rd party cost more than $400. Saw this one and picked it up. The watch is great on many aspects. Here are some pros and cons: 1. Relatively big watch but not too big and heavy. 2. Large display that is easy to read, even in very low light. The LED light that lights up display from left side is bright to show time in dark. 3. The ABC functions all watch very accurately. If not, you may have to calibrate it w/ 1 or more equipment; but once set, it's very accurate. 4. Solar charge works very quickly. On a bright day, under sun in less than 2 hours I got full charge (Shown as "H"). 5. Watch goes to sleep mode when in a dark place for too long, saving battery power. It has two steps. All are in the manual. 6. Time is very accurate due to atomic time keeping. Cons: 1. The belt. Not sure whose idea it was but the end segment of the belt with grooves in it has a protruding part, a locking looper type part. This part prevents the belt from sliding out from the buckle. However once you put your wrist on, taking it off becomes a choir as you have to struggle with this piece to slider under the buckle. To make matter worse, the buckle has a protruding rectangular hole as well where this looper gets stuck. This is very frustrating when you want to just take the belt off but instead spend more time struggling with this tiny piece. 2. The big display could show a lot more info but does not. This is a waste of space. Pressing the E button (Left top) will switch few info (baro, date, day) but nothing else. Wish it could show more. Just look at the picture and you will see that the left side of "seconds" there is room for other info to be shown. Perhaps the world time? But it does not. So to watch WT, you have to press the D (Left bottom) button several times. Other than that, it's perfect. 3. As far as I know from the manual, you can't quick swap Home time with World Time. This means you have to manually set your time for both. This is an issue for those who likes to travel a lot. The Edifice series has an easy way to do this. This one doesn't. I suggest you get a new belt as the belt it comes with is good but may cause some annoyances. As for the rest, considering the sensors and updated hardware you get in a watch, this is way too good for not having a 5 star. Can't really be that picky about the smaller details but they are there for you, if you are looking for specific style/preference. Overall an amazing product. Get it if you want a rugged, hard body, tough watch.

So far, this watch is amazing. It looks bad-astronaut with the full-size look, military vibe, and negative display. The features exceed what I ever imagined I would want in a watch, but now that I have them, they are fun to experiment with and I really enjoy knowing they're there. MUST HAVES: - The solar power and multiband 6 (atomic sync) are must-haves, for me. I don't want to have to babysit and potty train my watch. I don't serve my watch; my watch serves me. - I wanted a watch that could display the time while the stopwatch and/or timer was in use. - I wanted big digits so I wouldn't need glasses to check the time. - I wanted digital -- while I love the elegant appearance of analog watches, I can't get over the fact that the hands obstruct vital parts of the watch every hour. That's unforgivable to me, hence my requirement for digital. - I don't want my watch to make me look like a dork. The ProTrek checks all the boxes. DISPLAY: The readout is extremely easy to read. Negative displays have a negative reputation as they are often difficult to read but this one is clear and crisp at all angles. Bright sunlight does NOT wash-out the display, it actually makes it more readable. In dim lighting it is harder to read than a positive display but it is readable, and besides, the backlight (and auto-backlight) are there for a reason. Additionally, given the large nature of the watch, I felt that the negative display suited it better. The dark appearance makes it easier to get away with having such a beefy watch. (I use the same strategy for my size 15 shoes: the darker the better.) BEEP: The alarm and beeps are plenty loud. For comparison, I also have the Casio G-SHOCK 5610u and that has a very hollow and weak alarm. The ProTrek is louder, but not obnoxious by any means. It's probably typical and what anyone would expect. EASE OF USE: If you want a watch to just throw on and intuitively know how to use everything, this one is not for you. It is not hard to use if you are willing to spend a few minutes to get acquainted with it. You will need to look up your latitude and longitude coordinates online (or on a map, I guess) and set them in the watch so that the sunrise and sunset times are accurate. BATTERY and MULTIBAND 6 SYNC: The first day I had it the atomic sync would not initiate, manually or automatically. I soon discovered ATOMIC SYNC WILL NOT WORK WHEN THE BAROMETER WEATHER ALERTS ARE ON. I'm not sure the reasoning behind this, but I assume it is a feature, not a bug. Neither the auto-receive nor the manual-receive work while the barometer weather alerts are on. (Go to the barometer mode, then press and hold the barometer button to toggle it.) WEIGHT: The watch is heavier than my previous 5610, but it's not heavy. It reminds me of my metallic band Pulsar watch. It's a very normal weight for a watch. Overall, it's not a cheap watch, but it's not extremely expensive either. It will satisfy your desire for usefulness and having cool gadgets without getting into smartwatch territory. I have finally stopped endlessly browsing watches on Amazon and youtube. I have found what I was looking for.

Bought it exactly 4 years ago (2020) albeit for $160 while on sale. This has been my daily "driver" and I don't baby it (nor abuse it)- swim in the ocean all the time, go hiking, etc. Do rinse it after salt water exposure, but am surprised all the buttons still work and not gotten stuck. Backlight is excellent, display very easy to read in (or out of) the water. Never ran out of battery (solar charging). Barometer/Altimeter and temperature sensors are the main reasons I bought it for all my activities. Only wish it had tide tables, but otherwise this has been the perfect activity watch. Replaced the wrist band recently, other than that it works without issues. Barring some minor scuffing/scratches around the bezel, it even looks good still. Zero scratches on the crystal, probably due to the raised "lip" (crystal being recessed well below the bezel) that takes all the beating. There's occasional fogging of the crystal (due to temperature changes?), but seems to be common with all Casio watches I've owned. Will definitely buy another one (or the upgraded version), especially when it's under $200 again. Was considering upgrading to a quad-sensor Gulfmaster with sapphire crystal (GWNQ1000-1A), but seeing the condition of the used ones on eBay, which all seemed to be severely scratched up, decided to keep using this one till it dies. Seems Casio just hit the jackpot with this ProTrek for quality finishing (ion-plated) vs. a more expensive Gulfmaster that ends up looking like schit...

Genuine watch if this will go on sale again i will purchase again

Exactly the watch that I wanted with the 20bar depth, good looks and solar powered. Basically, the same as the other Protreks north of $600 or even north of $1000. Very quick delivery too

見た目も格好良いし、多機能のソーラー電波なので楽しさ満載。海外にも人気があるようで、今では買った当初の倍額に…。

Superb Watch - much more legible than others I've had of the same function type from Casio

Bought this as a gift and must say my partner loves it . Not sure ab8 the functions as he was the one that done all the research on these types of watches, but he loves it .
