Review: Great Atomic Solar Watch -- Stylish and Durable - I had an older style Casio Pro Trek Atomic Solar watch that had no mechanical components. I think this version is much more stylish, and I find it easier to view. But I will warn anyone buying one of these that because it does a lot, unless you have a better memory than me, you'll find yourself referring back to the included manual to learn how to do some things it's capable of. But that's more a critique of me than the product. My only real complaint is with the nightlight. It's clever in that it uses an integrated UV LED to charge the luminescent hands, but because of the angle, it really doesn't do that good a job. So nighttime viewing is not as good as with, say, the fully LCD versions of this watch. But it does everything it says, I've never had the battery run below H (high), and it's quite durable (I wear it every day and I'm both quite active and do a lot of hands-on activities that should have scratched it up a lot, and yet it still looks as good as when I took it out of the box). My only long-term concern is whether the mechanics will eventually fail (my expectations are high since my previous all LCD Casio is over 14 years old and still works fine -- including all of the sensors).
Review: ProTrek Beauty - 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

## Questions & Answers

**Q: What is the difference between this watch (prw-6600y-2cr) and the prg-600yb-2cr?  there is a significant price difference on amazon.**
A: The prw-6600y-2cr has atomic time keeping (multiband-6).  The prg-600yb-2cr does not have atomic time keeping.

**Q: Why is this watch now $100 more than it was a month ago??**
A: The price on this watch fluctuates. I don't know why amazon does this but likely to offset revolving discounts on other products.

**Q: Where is this watch made?  Is it made in China?**
A: Casio Products are manufactured in factories located in Japan, China, Thailand, and Malaysia according to factory specifications.

**Q: How do I know this watch is a genuine Protrek?**
A: I would think that you’d be getting the watch with all the Casio paperwork and guarantee. I would doubt there’d be a way someone could supply all the Casio paperwork and packaging and enclose a counterfeit watch. I love mine. Also, you could probably call Casio and they could guarantee authenticity.

### ⭐⭐⭐⭐⭐ Great looking, accurate and functional watch
*by K***B on June 8, 2023*

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.
