Too bad Amazon stopped allowing us to comment on reviews. Today's most popular review complains about a "LOW BATT" indicator, but he also states he uses the auto-light feature that illuminates the watch with a rotation of the wrist. That is the cause, and that feature should come with a warning from Casio.Avid outdoorsmen/boys, my sons and I all wear Casio three-in-one watches. One son's watch went through a LOW BATT episode. Since his was identical to the one I wore at the time we tried swapped watches, but since this didn't help, we knew it wasn't a user issue. I compared settings and found the only difference to be the auto-light active on my son's watch, and that turned out to be the problem. I turned it off and problem solved. We traded back and now more than a year later both watches are going strong, although mine is now strapped to the arm of another son. Those are the PRG-270 by the way, an excellent and bargain-priced watch -- especially when you can find it new from Amazon for under $90, as I did back in March of 2017. I don't know why Casio watch prices vary so much on Amazon, from Amazon as the seller.To wit: I paid $139 for this, my PRG-600, just over a year ago in June of 2020 but today it's listed for $189. It's worth $189; I was shocked when I stumbled upon it at the $139 price that was not any kind of deal, lightning or otherwise.I love this watch. It is thick and heavy, but I'm a middle-aged man who was born wearing a man's watch, so I'm used to it. I had a Swatch back in the 80s and I've had an ultralight dress watch or two but honestly, give me something I can feel, something I know is on my wrist. This does that and it looks great, too, but it doesn't scream money, so I'm not afraid to wear it in a questionable neighborhood.Typical or not I don't know, but my copy is not as accurate as other Casio watches I've had. Still, it it's not bad. It has lost a total of 26 seconds since I bought it, including 16 seconds between the last I set it in November of 2020 and today, July 23, 2021. (I set it to an atomic clock and make a note in my phone's calendar every time I set a watch, noting how far off it is.) This one might not be as accurate as my other Casios, but it is at least consistent. And two seconds per month isn't bad -- I've had much worse. When I was a kid I'd have been delighted with a watch accurate to two seconds per day.The only other caveat for you to consider is this PRG-600 uses the stem to set time and other functions, in a process that is not intuitive. You will not be able to adapt your experience setting Casio digital watches to setting this. I cannot say whether older digital-analog watches used similar procedures because this is my first triple sensor digital-analog watch.I suggest downloading a user's manual from Casio's website. It's free, and as with any Casio watch, to get the right manual you need only the four-digit module number that's engraved on the back of the watch. On this one it's 5497.Overall this is a nice watch with little to fault. Sure, it could be a bit thinner, and despite my earlier comments, a skosh lighter. I'd like it to have a feature to unblock the digital display from any mode, not just modes that require the display (maybe with a long-press of a button). And of course atomic accuracy would be nice, but that comes with an increased price I cannot justify. At this price point this watch can't be beat.

I ordered this to replace a much older Casio. I like the size on this watch, it is easy to read. The varoius options are easy to access and the LCD is easy to see. I had ordered a different model and returned it because I had to use the backlight to read the LCD. The luminescence is very good and lasts all night.

Fins, I’m a entire Army Infantry NCO and I’m picky about what watch I wear since it has to be tough. I bought the same model as in this listing but a friend of mine really wanted it so we did a horse trade and I bought a replacement for $182 in the used/renewed category recently. This watch is very comfortable to wear and it very durable and resistant to scratches. I prefer “stand alone” technologies instead of something requiring wi-fi to access its main functions. Always having a back up compass and other features is something I love on these ABC watches. I’m in my mid 50’s and this watch doesn’t look weird or huge on my wrist as some may think. I swapped the OD green wrist band for another OD green wristband I bought off of Amazon, it’s just has a little more heft to it but the original band is perfectly fine. Like most men my age, I prefer an analog watch face with larger dials so it’s easier to read in low or, no light environments or if I’m not wearing my glasses, lol.The lowest price for this model is on Amazon, eBay sells these for around $250-$330 which still isn’t bad but I prefer to look for a cheaper price. Once the inventory of this model are sold out, the prices will climb dramatically on re-sale websites so I suggest you get one….or two now so you can save some money in the long run since the inventory is starting to dry up. Setting and adjusting the watch is simple, the “smart dial” allows for direct time setting instead of spending a lot of time trying to find your own time zone. Next month I’m buying a PRG-650 to add to my collection of Casio Pro Treks since the price is still affordable on Amazon.You will not be disappointed!

I really liked the looks of the PROG 600 1CR as pictured in all on of the videos and Amazon ads. But I had a few reservations. I figured I would buy it and then make my decision when I had it in my hand. Here were my concerns. First I was really concerned about the size. Secondly I wasn't real crazy about the silver bezel. The best I can figure out is there are a lot of guys out there with tiny wrists. My wrists aren't big, 7.25 inches, and let me say this watch looks great on my wrist. Funny thing, under normal lighting and not the scrutiny of the lens and flash of a product shot and the bezel seems to reflect darker shades of light causing it to drop back out of noticeable sight thereby reducing the what might seam to be a larger footprint . So my initial concerns vanished in the first few seconds out for the box. I have 20 watches, I think this is my new EDC, (every day carry).Things to know. There is no Sunrise Sunset. It will not save a bearing while in compass mode. Good news, I really don't use those functions much. I like those functions on my 9400 Rangeman and the bearing saver on my Mudmaster GG1000, but they are not that important, as long as the compass points north and indicates a bearing then Im just fine with the PRG 600 1CR . Which brings me to a very important point. The 1CR is a positive digital display. I will never buy a negative display again, you just can't read them when you need to. Keep in mind the Hand Sto feature makes up for the lack of the two I mentioned.To wrap it up I ordered this watch a total of 3 times. Two times I cancelled the order because of the first two reasons I opened with in addition to the fact that who in their right mind needs 20 watches??? I'm glad I ordered it a third time and did not cancel the order. This is one nice watch. If you think you want it, trust me, get it. You will not look back.
