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

Nice watch.
This watch's best feature is the large screen, which displays the full date (including year) right below the nice large time digits. Buttons operate well with just the right amount of pressure needed. Even though it's an LED, the green light clearly illuminates the whole screen. The alarm chimes for ten seconds, sounding ten groups each of one short and one long beep. Alarm volume is middle of the road; not as loud as the W217, but not nearly as quiet as the GWM5610. Alarm volume is on par with the F-91W and DW5600. In every mode but timekeeping, the current is displayed in the lower left corner. When I bought the watch, I knew it didn't come with a countdown timer (can be activated by opening the watch and de-soldering a jumper) or multiple alarms. Neither of these features was as important to me as dual time or the well-organized time-keeping display. The gap between the spring bars and case is quite narrow. A NATO strap cannot be threaded directly under the spring bars; instead the spring bars must be removed, the strap placed in position, then the spring bars reinstalled on top. The watch looks great on a NATO strap. Finally, the watch is comfortable. The stock wristband is nothing fancy, yet it's very comfortable. The watch "disappears" on my wrist. On my 8-inch wrist the wristband has five extra holes. If you want all the day's key info in one place, plus an extra time zone, plus an alarm and stopwatch, then this watch should satisfy you.
