Gets My Stamp of Approval as a “Certified Moon Machine”
Changing the time and other functions: I’ve been to a watch repair shop several times in the past few years to have a battery replaced, and in two shops I was asked if I could leave it overnight. I was amused to find out why they needed 24 hours to replace a battery, which is because they are embarrassed about needing the time to find someone who knows how to set the time etc. The last guy I went to who wanted 24 hours confessed and told me he had to have his wife figure out how to set the time and whatnot. Another person who left a review on this mentioned he was able to change the functions without the manual. Even as a retired engineer I’m not quite that good. It’s nice that most the gadgets we get these days have a user manual included, but if you use it you’d better have a good magnifying glass to see that tiny print. Thank God for those all so nice pdf user manuals available online. Pros: 1- It's fabulous the way the analog hands automatically move to the correct time position after you set the digital time. 2- You can be at the North Pole or one of those places where it’s dark for six months, and the charge on your solar watch battery will last that long (actually ten months). 3- The battery never has to be replaced. 4- Displays both Digital and Analog time. 5- Glow in the dark hands and 12, 3, 6 & 9 positions. 6- Battery indicator tells you if the battery is low, middle or hi charge. 7- You don't have to have sunlight to charge - Charges well with indoor lighting. Went from Middle Charge to High Charge in a few hours with indoor lighting. So don't worry about cloudy days. 8- The low cost for such a good quality watch with so many features does not break the bank. Cons: 1- Minor – The analog glow in the dark feature isn’t very bright, but it’s okay since you can press the light button that illuminates the digital time. 2- Minor – List of city codes is limited. Many cities are not on the list. But if your city is not on the list you can pick one that’s in the same time zone as you, which could mean you may not have the automatic Daylight Savings Time, and may have to change it manually. 3- Minor - The sound of the chime or alarm is not very loud. Yes, I admit to being a gadget freak, and as such I will also admit to this being my second solar powered watch. The first was a little less money and does not have a rechargeable battery but I decided to keep it because it looks nice. This one is my favorite because the battery is rechargeable & I like all the features. It's my second Casio watch. The first one I've had for several years and I love it as well, with all it's features of Altimeter, Barometer etc. So I can definitely recommend Casio watches.

GREAT BUY! This watch is freakin' awesome.
Okay, so I've spent thousands of dollars on over dozens of fancy watches over the years that are a pain in the ass because you have to replace the batteries and adjust the time and dates, mostly because I thought if you want something that looked nice, you gotta pay big bucks for it. I've recently become a salesman, and the first thing they told me about my appearance, is you gotta shave the beard, and you gotta lose the fancy shiny expensive looking watches...because it made me look like I was into it for the money (that's a no-no). One of my coworkers who makes over 100k a year said he bought one of these for $40 at a place that rhymes with moles. It looks sporty and less dressy, and if I insisted on wearing a watch, go for something like this. When I saw this watch at the department store, I thought it looked pretty sweet. I knew nothing about what it did, then read the reviews on Amazon and decided for $30, who gives a crap? If I don't like it I'll send it back. I've had it for an hour, been tinkering around, and all I can say is WOW. First thing you need to do when you get this watch is adjust it to your time zone. What's awesome about this, is that it KNOWS what time zone you're in, *IF* you know how to adjust it. PRO TIP: Hold down the adjust button for five seconds and the hands will move by themselves to 12:00. Then hold adjust again for 2 seconds and the watch will AUTOMATICALLY set the digital and analog time (yes, the analog will spin clock or counter-clockwise on its in to match the digital) to your time zone on its own for you. *MIND BLOWN* So anytime I get on a plane and fly, all I have to do is repeat this sequence, not even know what time it is or the zone I'm in, and the watch resets the time for me. KICK FRIGGIN ASS! Not to mention it has a second time zone so you could know what time it is in Bangladesh (useless for me but cool nonetheless), 5 alarms, a stopwatch, military or standard time, the date, the day of the week, and probably a bunch of other features I'll learn about eventually but will probably never use. Then it's got a light for the digital that you can program for the amount of seconds you want it to light up! SCHA-WING! It's also solar which means I'll never have to pay for a battery because I'm outside in the sun for atleast an hour every day. Waterproof, lightweight, feels durable on my wrist. The glass over the watch feels cheap, but to be honest, who cares it's a work watch. And if the glass happens to break, woe is me, it's going to be another thirty bucks. Boo Hoo. The manual is a beast and after 20 minutes of reading, I gave up and went to Google, and found my answers. Why rifle through a manual with the internet on your side? When you ask a question just include Casio Module 5208 and many of my questions were answered. Never thought I'd come upon such a great watch that looks so good while being so cheap, and has so many features, for such a great price tag. 100% satisfied off the bat, everything else is icing on the cake. If you're on the fence, GET THIS WATCH you will NOT regret it!

G-Shock lite
This is almost the perfect watch. Consider it as a G-Shock lite. It has everything you want, and nothing you don't. First off, it's a 46mm case, so that puts it in the 3/4 size G-shock range. It also doesn't have the isolating shock protection of a G-shock. If you can live with that... read on. The watch has an uncluttered, clean, large dial face (easy to read at a glance). It actually has the largest solar panel surface of any Casio watch out there, since it only has the one small digital window (vs the 3, or more, that G-shock's have), which means the battery is easily topped off and almost always at high charge. It is also SUPER light (lightest watch I've ever had). It's comfortable, even though I have tiny wrists (6.25"), although it will have gaps on the sides of the band/wrist if your wrists are as small as mine. It's 100m water resistant (don't use the buttons under water though). All in all... it's the best budget G-shock-ish watch out there. It will have FAR better battery life (due to it's large solar face, and minimal functions), and it's lighter than those. I actually returned a nice solar/atomic G-shock for this instead. Modern quartz movement is accurate to within a couple seconds per month, so what is the advantage of atomic?? It also has better battery life since it has more solar surface than the G-shock I had, and I don't use the other features of the G-shock anyway... so this was a no brainer for me and I couldn't be happier! Now on to the 4 of 5 stars... The illuminator feature is a joke. It only illuminates the tiny digital portion of the watch face. C'mon Casio.. this watch has more solar/battery storage than any of your other watches and you chose to only illuminate the tiny digital area?? Shame on you. But that isn't a deal breaker for me, as I'm not often looking to check time in the dark. But please, Casio, at LEAST give it an entire face led light (or even better, back light). It's just absurd that they market this with illuminator plastered all over it, when that's it's worst feature. The other negative isn't really about this watch in particular... it's about Casio. Casio's instruction manual's are horrible. You're far better off getting instructions on changing settings from YouTube, as the instructions are practically useless. The only other thing I could ding it for is the plastic clasp.. but for a watch this light, I don't really think it needs a metal one. It seems to do just fine. If not for the lighting issue... this would easily be a 5 star watch for me.

Very Nice Watch works well
Great watch so far solar recharging works great easy to see and read and works great for what I want pretty much being able to see the time and date really don't use any of the other functions on the watch very comfortable band seems very sturdy and well made I have had a number of these style watches over the past several years and really enjoy them but they last about a year or year and a half and either the strap breaks or the battery runs out This Casio so far seems much sturdier than the cheaper watches I have owned and the solar powered battery will allow it to last several years so for me its just what I wanted a simple watch that is easy to read, looks good and should last me for 10 years or more just what I wanted and at a very reasonable price for what you get in the watch will update after I've had it a few years to see how it actually holds up but so far seems excellent and a great buy

Great watch
This watch looks much better than the picture. It really is a great watch. There are few things I wish it had or made different but they are really small. Casio watches last a really long time and I am sure this one will be no exception. It's big, very light and checks almost all the boxes. Strongly recommend.

Good price, great value
For the money, this may be the best watch I own. very durable and can withstand heat and water enough to wear while working in a kitchen. It's now a bit dinged and banged up, but I bought it as an everyday watch for work and I've absolutely gotten my money's worth. Highly recommend 🙂

LCD a bit too small/ hard to read
The "Analog" part of this watch is easily readable though it is a bit weird to call it Analog since it is tied directly to the digital part of the watch. You "set" the digital watch and then watch the analog part of the watch automatically match the time you set on the digital watch. That's all fine and dandy but the digital watch face (LCD) is a bit small and harder to read than I would prefer. Not helpful in that issue is that there are periods of time when the minute or hour hand will be sitting right over top of that display obliterating part of it and making it harder to see. Finally, also directly impacting my own personal satisfaction is that part of the display is pretty much set to show the seconds in digital form and that part of the display is where I would much prefer to see the year part of the date, or would prefer to have the display show me DAY-of-week MONTH and DAY (so something like MON 1-13 as an example). There's also the space that is used there to show the charging activity from the solar charging. I don't mind that but think it would have made more sense to add that as a separate display in another lesser used area of the analog watch face. If that was done that would leave more room for the digital display to be more readable for persons that want to clearly see that part. I do like that the watch has multiple alarms though find that isn't really able to handle all of what I would like to do. Unlike a smart watch that would be tied to my phone and pick up a different alarm each day if I needed it, this watch offers a single time for the alarms that are set and doesn't care about day-of-the-week or date at all. So if I need a reminder on Wednesday at 1:30pm, I can't set that up on this watch unless I want the same alarm every other day of the week. Similarly, I need or want an alarm at 9:25am to remind me of a Monday-Friday meeting and I get to have the same alarm on Saturday and Sunday even if I don't need it then. I know, I know, this isn't a smart watch and doesn't have that much flexibility but I still wish for a bit more. I also know if I it was as flexible as I hoped for it would be harder to set the alarms on this watch, especially since it isn't a smart watch and has no interface over to any external source such as a phone or computer. Since I can't use a smart watch during my normal work day (prohibitions in my work place and all that) and can't have the cell phone there anyway having a simpler watch that doesn't offer or use Bluetooth or Wi-Fi is a requirement and this seems to me to be among the best of my available choices. For the price point this is a nice watch. Not perfect, but definitely useful and delivering fair value. Younger eyes might not see the issue with the digital display. I didn't separately rate water resistance as I'm not really trying that hard to use this where I might need water resistance. (Yet). Same for Timer Function which I normally don't need to use.
