Great watch

Color: Black Style: W-800H-1AVCF

Great watch. Great price. I tried to find somethin like it at local stores but did not find what I wanted. Amazon had what I was looking for. Very waterproof. I wear it swimming, only taking it off when I go to sleep.

Coming up on 3 years since purchase and still going strong.

Color: Black Style: W-800H-1AVCF

Bought this 2 years and 8 months ago and it's still great. In that time, it's drifted 27 seconds (e.g. at 8:00:00 it now reads 8:00:27). **EDIT** This drift is inaccurate. Updated at bottom of review **END EDIT**. For me, that's not a big deal, but figured I'd mention it. I wear the watch face-side down on my wrist, but it only accrued one mild scratch in all that time. Nothing terrible. I bought this watch because it had 3 things; the 24-hour time, the day of the week, and the date on a single screen. It's the only watch I've found that had all 3 of those. To find all 3 in a highly rated and CHEAP watch? I bought it in a second and haven't regretted it since. I actually returned a better and more expensive watch (Casio DW5600E-1V) before eventually finding and loving this. I especially love that it orders the date in Year-Month-Day format. I live in the US where Month-Day-Year is the norm, but I also work with thousands of computer files where the best way to organize files by date is with a Year-Month-Day system (e.g. 221102 for November 2, 2022). It's just a little nothing thing, but I love this watch for it. I should note that the watch band snapped off back in August, 2 years and 5 months after getting the watch. That's happened with other watches with resin bands that I've owned, always around the 2-3 year mark. I heard it's from sweat or showers hardening the resin or something. That could make sense as I never take mine off except when I'm rock climbing. Regardless, I just grabbed a cheap 18mm silicone watch strap for 12.99 and it's been fine ever since (bought silicone because I heard they don't snap. I'll update this if it ever does). I plan to use this watch forever. If it breaks, I'll buy a new one for the price of a burger + onion rings. I've gone through a dozen watches over the past 25 years or so, but this is the first one that I loved. It has everything I want without a bunch of other useless expensive crap that I'll never use (looking at you, altimeter; and that's coming from a hiker). It's cheap, reliable (anecdotally), has a fast band replacement process, no feature-bloat, has large text, and is DECENTLY water resistant. The only downside is that the watch isn't 200m water resistant. If it was, it'd be perfect for me. Anyway, I don't go surfing/swimming with it, but it hasn't fogged up after 2+ years of showers, rain, sweat, etc. If you want a cheap watch, I recommend this one (unless you're an avid surfer). Or if you're like me and willing to fork over $100 for a watch, maybe buy this anyway. It's certainly much better than the $21 price-tag would have you believe. **EDIT** 12/12/23 I made the above review over a year ago, but I realized that I couldn't verify that the 27 seconds of drift was accurate. Well, I decided to run a little experiment over the past year and record the drift every few months (basically whenever I remembered I was even doing this) and it turns out that the drift WASN'T accurate. After a year, my watch drifted 58 seconds. To get that 27 second value, I might have reset my watch whenever we had daylight saving time or something, hence the inaccurate drift. Anyway, I included the recorded values below (MM/DD/YY format) in case someone is interested. Also, I used time.gov for the baseline comparison. 12/11/22 9:55PM - 0 seconds fast 01/19/23 6:18PM - 5 seconds fast 02/22/23 12:48PM - 10.5 seconds fast 04/15/23 9:00PM - 18.5 seconds fast 05/08/23 8:22PM - 22 seconds fast 06/27/23 12:52PM - 30 seconds fast 09/06/23 8:15PM - 41 seconds fast 11/05/23 7:18PM - 51 seconds fast 12/11/23 9:55PM - 58 seconds fast This basically means my watch drifts by a little more than 1 second every week (1sec/~6.29days). For my needs, that's fine. I'm not doing anything in my daily life that requires long-term precision to the second, and I have to reset it every so often anyway for the aforementioned daylight saving time, so I don't mind at all. Other than that, the watch still works great (nearing 4 years now) and the "new" silicone watchband is still great too (although it hasn't hit that 2-3 year breakdown point yet). So, all in all, still happy with it. ... show more

A Phenomenal Little Watch!

Color: Black Style: W-800H-1AVCF

I just got my watch yesterday, and after a full day of use, I am happy to report that this is a very solid all-around watch. I got this to replace my previous daily driver, the Timex Men's T49997 Expedition Gallatin Black Fast Wrap Velcro Strap Watch, which started giving up on me after nearly two years of usage. I wanted an inexpensive watch to replace this one, and since I don't really go to any fancy meetings or upscale restaurants, and when I do, I have the appropriate watches for those events. I needed something that take a hit against the occasional door if necessary. Looks weren't really that important to me. Seeing this watch on sale for less than $10, with a boatload of positive reviews, I knew I had to jump on it. When I first got the watch, I expected it to arrive in very simply packaging, nothing too fancy, especially at the price I paid for it. It came in a nice little blue box, and while it wasn't the most premium packaging, it certainly didn'nt seem as though the watch I purchased was cheap by any means. Seeing the big Casio logo on it also reminded me that despite the price I paid, this was supposed to be a quality, durable product, and all of that was confirmed for me the moment I pulled the watch out of the packaging. Its design isn't anything to write home about, and neither are the materials that went into making the watch (no fancy gold here!), but the rubberized strap seemed to go hand-in-hand with the material of the watch's face. The uniform black coloring on the watch makes it look utilitarian, but distinctive at the same time. It might not impress anyone at a party, but then again, that wasn't my intention when purchasing the watch. The two most important functions of a watch for me are its ability to tell the time and its durability. The screen on the watch isn't a 1440p Super AMOLED display with RGB coloring around the mantle, but for the purpose of simply telling time, it is phenomenal! Anyone who owned a digital watch in the 90s will know how it looks. The grayscale image is clear, and the text is extremely easy to read, especially in bright daylight. The time is in a font that's large enough for anyone with moderate eyesight to understand, and the watch even tells us the date, time and day of the week! The watch has other functions like "Alarm" "Stopwatch" and "Timer," but I haven't tested any of those modes out, so I won't mention them here (still, it's nice to know they're available!). Overall, from what little time I've spent with the watch, I can easily say I'm more than satisfied with it. Casio has given the battery a life expectancy of 10 years, but well, if it dies before, I'll update this review for us. If you're just looking for an easy watch to understand, something practical and durable, then look no further, especially if you can find it for less than $10! ... show more

4 stars... BUT..

Color: Black Style: W-800H-1AVCF

I truly believe this is a solid 4 star watch, BUT highly positive 4 stars. Reasons for NOT being 5 stars: 1. Does not come stock with a countdown timer. Although you can (and I did) YouTube a quick guide on how to add one. Really easy and completely transforms the functionality of the watch. 2. The LED green light is not the BEST, but better than most. In my opinion, the orange LED from the Casio AE-1200WH would have been a huge upgrade. If Casio would have made this watch with the above 2 things, this watch would have been a 5 star +++ major home run and I would have gladly purchased for even double the price. Other than those 2 things, and at around 20 bucks, this watch is unbeatable. Digits are easy to read, 100m is plenty of water resistance, it's lightweight, and not too big or too small. Straps are easy to remove and upgrade as shown in my pictures/video. Honestly what more do you really need? The biggest positive in my opinion is the ability to show the current time while you are in stop watch or (the manually added) count down timer mode. This is something the overly hyped TikTok and YouTube viral AE-1200WH aka "Casio Royal" lacks. Overall, very solid purchase and extremely useful. Next best thing outside of the G-Shock 5600E-1V. ... show more

Quality Watch, Good for SCUBA

Color: Black Style: W-800H-1AVCF

I have been using this for a few weeks. I've done a couple hikes that included cliff jumping, climbing, and water for multiple hours. I took it scuba diving for two days and we were in the ocean constantly. It held up perfectly. I dove for two days averaging 30-40 feet deep but 65 at the deepest. It did great for all of that. I used the stopwatch underwater multiple times. The display is crisp and clear. Buttons are perfect size. Easy to push even with scuba gloves but they don't dig into your wrist. The light works great. It doesn't stay on for more than a second unless you hold it but I like that. Less battery wasting. The strap is a little long. I have small wrists so I cut it shorter. I regretted that in a thick 7ml wetsuit when the long strap would have been nice, but it still worked. I've seen others exhange the straps. The alarm is enough to wake up with. It beeps 10 times and then stops. It will go again every 5 minutes if you have the snooze setting on. So far I have one tiny scratch on the surface. Only noticeable if you really look for it. That's pretty good for the abuse I've already put it through. My favorite part about it is that it replaces having to get my phone out or turned on for time, stopwatch, and alarm while I'm backpacking/hiking/diving. People think that you need to have expensive gear to have fun outside and that's usually not true. ... show more

Not Bad For A Replacement Watch.....

Color: Black Style: W-800H-1AVCF

I got this watch to replace an Old Timex USB watch that finally gave up the ghost on me. I wanted one that would at least have the full time (hours, minutes, and seconds) on the front without having to press any buttons to see. I also wanted, if I could, get one that had the date, day of the month, and day of the week on the front to. I wasn't as keen as having the week, etc. as the hours, minutes, and seconds. I looked first to see if they still made a watch like my old one as I really liked it and it's features and just wanted to replace it. What I found was that unless I wanted to pay an arm and a leg, I would be out of luck. That wasn't an option for me. I then started checking out the watches that I liked the look of. I found this one as I was looking over the Casio watches. I liked the overall layout and it had all I was looking for right on the front without having to press additional buttons to bring those items up so I checked it out. The price was right for me as all I wanted was one that would give me a watch to replace the old one. Got it in and checked it out. It was just about what I wanted all the way. The few minor things I ran into were want you normally hit on it getting something new the first time. The settings buttons and where things were sort of confused me for a bit until I got used to them. The watch is a bit smaller than my old one and I had to get used to that and it's lighter too. On the plus side, it has the full date, time on the front (That includes year, day of month, day of week, hours, minutes, and seconds.). It has an hourly chime, a stopwatch, and an alarm function that allows setting the alarm in a number of different ways. You can set it for the same time everyday, every other day, once a week, every other week, and even once a month too. It also has a dual time feature that lets you keep track of time in another time zone. Although the alarm is not as loud as my old watch was it is loud enough to hear easily. I found this watch to be just what I needed as a replacement for my old watch. A good buy for me. ... show more

Practical and actually pretty nicely designed.

Color: Black Style: W-800H-1AVCF

Many people don't wear watches anymore because they use their phones, but you still can't beat a watch for convenience. This would be a good choice for people who simply want that convenience. Just glance down at your wrist, and there is the date, day and time in large readable characters. The watch comes with an alarm, stopwatch and second timezone feature, none of which I consider all that useful. Still, that's a pretty minimal feature set, and minimal is GOOD; the fewer bells and whistles, the less complicated a watch is to use. The 100m water resistance is also a huge plus in the convenience department; that's the minimum water resistance it's actually safe to swim with (ratings are based on completely still water). Add to that the fact that it's accurate enough you only really have to reset it when daylight savings comes in and out, and you can just put this on your wrist and forget it. The electroluminescent display backlight is adequate -- certainly better than the Casios from the early 90s, but not quite as uniform as Timex's Indiglo feature. Also automatic backlighting would have been nice, but is not to be expected at a $13 price point. The low price also means you get a resin (marketer-speak for "plastic") strap, but I actually think resin works better than the more expensive silicone for something this light. Silicone can get uncomfortable when you're sweaty. If you have a thing against plastic you can replace the band with any 18mm width after market strap. In the image I've attached, I've paired this watch with a "Goldfinger" style nylon NATO strap -- yes, that's a $40 band on a $13 watch, although you can get cheaper versions here on Amazon for under $10. The point isn't how much the band costs relative to the watch, it's how much you enjoy it. And this is a watch you actually can enjoy for its aesthetics. Square is a good shape for a digital watch, and the size delivers plenty of legibility without getting in the way of sleeves or catching on things. It's not easy to see in the Amazon image, but the watch also has subtle hints of color -- blue outlining around the crystal and a little red lettering. These touches are subdued but elevate the design. That may sound funny to say about a $13 watch, but why shouldn't something like this be designed thoughtfully? As a watch collector I have maybe five digital watches in my collection, but this and the iconic F-91W are the only ones that get regular "wrist time". ... show more

This thing is TOUGH, but the choice to buy it was EASY.

Color: Black Style: W-800H-1AVCF

First and foremost, I was not, in any way, shape, or form, compensated for writing this review. I find myself depending on reviews to make my decision of purchasing a product or not; so here's my contribution back to the Amazon community. As of this moment, I have had this watch for about 2.5 months. I wanted a watch that could keep track of time while I ran. This watch comes with a timer function that I use quite frequently. It's simple and does the job. I can't quite figure out if it has a split time, however. I end up just timing the total time of my run most of the time anyways. Why did I give this product 5 stars? 1) At less than $15, its price tag alone should at least interest you. 2) It keeps track of time accurately. I had no issues of it running too fast or too slow and having to re-calibrate the time. 3) It is simple. Not only in looks, but in function. I wanted a watch to keep time; I don't need it to keep track of my sleep cycle or how much I ate throughout the day like a smart watch. This watch is simple and clean and it's very easy to read too--in light or dark. 4) It is DURABLE. Over the past 2.5 months, I've been pretty rough with this thing--accidentally banging it on walls; dropping it; swimming with it (it's waterproof)--and the watch still looked as good as new while not messing with its time accuracy. I was finally able to scratch the face of the watch by sliding it 30-40 feet on the gym floor into my bag (which was stupid--I should have just walked over lol). Even then, however, the scratch isn't that noticeable and it is still easy to read the watch. If there's one thing I don't like about the watch, it's the beeping sound it makes whenever you press one of the buttons (excluding the LIGHT function). However, I realize that it's actually quite useful. For one, it gives me assurance that I pressed the button. Two, it makes a different beep when you change the mode into the main time (the beep is higher pitched)--this helps you know that you are on the main screen and not accidentally on time, alarm, or dual time mode. In conclusion, if you want a solid watch to simply keep track of time, then you can't go wrong with this one. Especially with that price. When this one dies out years in the future due to a drained battery, I would strongly consider this one again. If you have any questions, just write me a comment. ... show more
