CasioPRW6600Y Series | Pro Trek | 100M WR | Compass | Alt/Baro-Thermo | Tough Solar Power | Atomic Timekeeping | 1-100 SEC Stopwatch | Countdown Timer | World Time

I've been wearing Casio watches for over 50 years and I must say this is one if yhe best looking watches they have ever made. It has many of the features the G-Shocks have withouth the super thick case. I am thin so some watches are just too large but the 6600 fits perfectly. If you look at the measurements be away they are adding the crown and buttons into the figure. I had also ordered screen savers to protect the mineral glass from getting scratched. I recommend it.PROS:Beautiful and masculine.VERY easy to read even at an angle.Nice size for this yype of watch.Many features but even though I won't be using some of them I need a compass.Atomic clock is a HUGE plus for us time police. 😃Solar powered so battery should last 20 years.World time and it's very easy to set.5571 internal movement is easy to use.Very nice silicone band with quick release.Plenty of band holes for thinner wrists.Black buckle looks good.Ither bands will fit.if needed.Easy to use backlight.Glow in yhe dark work fairly well.LOUD alarm.Negative display screen is easy to read.Tells temperature but it must be off your wrist for at least 29 minutes. (This is normal)Altimeter must be set to be accurate and then it works well.Tutorial videos available online.Packed in a wooden box so it looks nice as a gift.CONS:Pricey compared to some other great Casio watches.Band does not have a locking or wratched keeper.Light could be brighter.FYI: Although not a thick watch it may be too thick for formal wear.Makes people want to be like you. 😬This is a fantastic watch. As I get older and my vision dims it's good to have an easy-to-read-at-a-glance watch. If you are looking for a G-Steel or G-Shock but watch something a bit classier this may be what you're looking for.Highly recommended

I've had this watch for just over a month now. While it took a few days to figure out all the options available on it, after watching a couple of Youtube videos, I figured it out. It is really quite intuitive once you get the hang of it.I was replacing another Casio solar watch that I have had for many years. I also have several higher end conventional Swiss watches, but this is the one that I normally wear. This watch looks great and has many useful features. I live in California, but it picks up the WWV signal from Colorado almost every night, so the time is accurate to the second at all times. It looks great and is comfortable to wear. I use and enjoy many of the features such as the stopwatch, altimeter and others.If you like the look of the watch, I would highly recommend it to anyone. It is well made, will save a lot of money in batteries and should last for many years.

This is a wonderful watch. It checks all the boxes, including solar charging and multi-band time update. It is very light weight and comfortable, It also fits my 8 1/4" wrist with enough extra band length to actually be secured by the band loop. (Big wristed people will understand :) )I have a GW-9400-1CR Rangeman that has all the same goodies but it is clunkier, sits big on the wrist, and the band is much less flexible. It also lacks the analog hands and hour markers that are much easier to read. The PRW6600Y Pro Trek is a better everyday wear.The flush mineral crystal is the only flaw in the design of this watch. Like others, I ordered and attached a glass protector that fits perfectly: Finenic tempered glass round screen protector 37 mm 3 pack.

I like this watch! I am an avid watch collector/enthusiast and usually focus on Swiss Automatics from the 50’s/60’s. As a result, I haven’t had a Casio “electronic” watch since I got as 11 y/o. However, I wanted a watch that I could wear and not worry too much about if I bumped it or scuffed it on a hard surface. So I was looking at Casio “G-Shocks” when I came across their “Pro-Trek” line of watches that I was hitherto unaware of. After researching the variety of features on the various models in this line, I settled on the 5571 model. As I was just about to “check out”, I saw the 6600 model, which essentially is the same watch, but it had the “Atomic Radio Signal” feature and was on sale for less than the 5571! Done! I was a bit concerned about the size, as I have smaller wrists and I usually wear watches in the 39mm-42mm range. This watch was advertised at 51.5mm, but I have to say, it “wears” a bit smaller. Don’t get me wrong, it’s a big faced watch, but I don’t find it offensive or “overbearing”. I also was anticipating a steep learning curve regarding the usage of features. However, it was fairly straight forward for this middle aged guy and probably a “walk in the park” for the younger generation. The build quality and fit and finish is very nice as Casios tend to be. I like the solar power feature and it only took about a half day long in the sun to “fill’er-up!” I just set it on a nightstand in the evenings and the little led bedside lamp seems to keep it “topped-off”. It’s still new, but I’ve never had any low charge issues. I love the accuracy, as it receives the signal broadcast from the Fort Collins, Colorado, NIST monitored Atomic Clocks. It also monitors other broadcast Atomic Clock signals depending on where you live. All in all, this Casio 6600 is everything I was looking for and has become my daily wearer (for now)! Definitely worth the $253.00 or so I bought it for! Hope this helps!
