Stylish and functional digital watch.

Reviewed in the United States on February 20, 2024

Color: Black/GrayStyle: W-800HM-7AVCFVerified Purchase

Fast take:
- Looks great
- Easy to read, lighting is pretty good
- Feels great on my wrist
- Durable
- Fantastic price

I recently rekindled my love for watches. I have a 300 dollar Tissot, 40 dollar Timex watches, and now this great value watch.

This is my new everyday watch that I can wear to work (I work as a biomed technician) and at home.
Easy to read and very easy to set it up with some quick glance in the manual. Lighting is good, I'd say 7/10 in low light conditions. Bumps up to 10/10 in pitch black. I don't use other functions other than the date and time as I will still use my phone for stop timer, alarms, etc as it's just easier to utilize the phone for them, you'll free up your hands as well. In any case, great that this watch has them.

The band is surprisingly comfortable, I won't change the band at as I found that it suits my activities quite well. I can clean this watch with soap and running water, something I'll never do with my other watches.
While I'm inherently careful with my watches, I don't have to worry about this one as it is the most durable watch I own (that is until I get a G-shock down the line).
The price. You can get any cheap watch in the same price range, but you won't find anything with this much value. It's cheaper than an afternoon lunch, and it'll last you for many years. I like this watch very much and I know you'll like it to. Just buy it already lol.

Quality Watch, Good for SCUBA

Reviewed in the United States on June 13, 2024

Color: BLACKStyle: W-800H-1AVCFVerified Purchase

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.

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

Reviewed in the United States on November 2, 2022

Color: BLACKStyle: W-800H-1AVCFVerified Purchase

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.

As is known, the negative display is hard to read in low light without using the backlight and I accept that. But overall verrrry happy with this watch. Its understated, lightweight, feature full and has great water resistance. It's perfect as a small outdoors activity watch; which is what I bought it for (beach, hiking etc). Didn't want to bulk up to a g-shock sized watch.

El reloj es buenísimo ya llevo unas semanas utilizandolo del diario,la correa de caucho no guarda olores aunque sudes mucho, el modelo como es color negativo se ve bastante bien en la noche y en el sol aúnque le de el sol directo se aprecia perfectamente la hora, si lo usas del diario es lo mejor,pero si es para el diario y trabajas en algo que ocupes mucho tus manos es muy MUY delicado el cristal se raya con mucha facilidad, ya que no es línea G-SHOCK, hasta con un trapo que no sea especial se raya mucho esa es la única desventaja,de ahí en fuera 10/10

Perfect for people of all ages

Reviewed in Canada on December 28, 2023

Color: BlackStyle: W-800HG-9AVVerified Purchase

This watch has some really amazing features that makes it, in my opinion , a much better choice than other more popular Casio models.

The case has the perfect size and it sits great on my wrist, and the display has large numbers that are very easy to see without my eyeglasses. The display contains all the information you need including the year in full 4 digits. It's also very light and water resistance is good. I don't submerge it anywhere really, but occasionally I take showers with it at hot temperatures , but the watch doesn't fail nor fogs. The strap is longer than other Casio models including the F91W, so I guess it will be adequate for people with bigger wrists.

For the price, it is a steal and I bought a second piece for a friend as christmas present. Highly recommended.
