Review: One of the best watch I've had. - 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.
Review: 4 years later and still going strong - 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...

## Questions & Answers

**Q: Watch arrived today.  Any idea where to get the little barrel pins that hold the band links in place?  I took two links out and the little parts flew**
A: Find a local watch repair shop, call first or contact the watch manufacture, I'm sure they will have them.

**Q: The watch can be calibrate in South America, more specifically Brazil?**
A: If you are referring to the daylight function which is based on latitude and longitude, yes. The world time functions include all international time zones around the world. The compass functions require user input of degrees magnetic declination.  You must have this information from a reliable source then input it for the travel area. I have used this watch and all it's relevant functions in North America, Asia, India and Australia but not South America or Brazil specifically. I will be traveling the Chile and Argentina in April and plan to take this watch.

**Q: Is the prw-3500-7cr suited to european area? i read there is also the model 3500-7er what's the difference?**
A: The manual says this watch can sync with radio signals from the UK and Germany, so it should work in Europe. I don't know anything about the 3500-7er model.

**Q: Why can't you send this casio men's pro trek prw-3500t-7cr to cardiff ? the customer pays you money. money is not necessary to you?**
A: No, it’s not necessary for me.

### ⭐⭐⭐⭐⭐ 2+ Year Review
*by B***. on November 4, 2023*

If I could only have one watch, it would be this one. I love this watch. This is the watch I wear all day no matter what I am doing. I have gotten paint acetone, automotive oils and greases, detergents, and all sorts of other substances on it. I have banged it against countless objects. I truly unapologetically use this watch. Here are the det's: Comfort: This is the most comfortable watch I have ever worn. This watch doesn't start to weigh on your wrist, get itchy, or make you feel like you have to shift it around from time to time. I wear it all day. I have even fallen asleep with it on. Durability: I am impressed with the amount of abuse this watch takes. There are some expected scratches, but even the wrist band and buckle are holding up well. Charging/battery: This is always on hi, even if I wear longs sleeves. It gets plenty of charge just from driving around or being outside for a bit. Functions: I had to calibrate the thermometer when I got it. It isn't going to give you a good reading on your wrist. It will pick up your body heat. I have found it accurate when it is not worn. Other functions work as advertised. Screen/reading: I have the autolight function enabled so it turns on briefly when you aim your wrist at your peepers. It can't be read well in the dark without it. The light is bright enough to read the full display. The light button is easy to locate and press with no light. In normal to low light, it is very easy to read. I prefer this display instead of the light back screen with dark numbers, like the previous model. But I'm sure that is subjective. Buttons: Everything is easy to press and find. There is a lot of texture on the buttons. Even with gloves on, it is easy to operate. To sum up, this is a quality watch! I won't go on about all it does and the size, that info is in the listing. It does what it promises and does it well. I would highly recommend it!!
