Beautiful, full of functionality, and ready to go from the moment you open the box.
This watch, being the 3rd smartwatch I've purchased, has outperformed every other watch I've owned. The companion app makes learning about your watch and keeping track of all of the available functions make this watch a must have for anyone in the market for a high end smartwatch at a low end price. The watch was fully charged and ready to go from the moment I opened the box. On a side note, this watch has an incredibly funny and super helpful AI companion that is fun to talk with and makes information finding a thing of ease. Don't look anywhere else, this is your watch, it will please you, I assure you. Buy 2, one for you and one for any friend or family member that might be in the market for a smartwatch, they'll appreciate it as much as you'll appreciate your own. Buy this watch, quit browsing, this is the one.

A lot of Easy to use features at an affordable well made digital watch tied to your phone.
Affordable digital watch with a lot of health / exercise features. after DL the app to connect the watch to your phone I found added feature apps like phone locater, take photo, weather, message, health and more. It does have a built in speaker, connect to phone to dial numbers. a big size face with tough sensor glass and the wristband is fixable for easy removal for charging. Unlike paying lots of $$$ for other watches this one seems to meet the features I was looking for in my first digital watch. Depending on what watch face you chose you can choose one that show the percentage of charge remains before needs recharging.

Great for the price
I'm sure the $300+ smart watches have more bells & whistles, but for the $40 I paid for this watch, I'm quite happy. It certainly does what I bought it to do. It comes with a pretty useful app. I do wish there were more instructions, though. I've had to figure some things out on my own. A couple of things I've noted in the interest of saving others a learning curve: 1. Putting the watch in low power mode when you don't really need the face to light up with a wrist raise greatly extends the time between charges. 2. You will definitely want to put it into low power mode before driving, especially at night, or it will drive you bonkers lighting up every time you turn the steering wheel to the right. 3. After charging, you might need to restart the watch to get it recording steps, sleep, etc. again. 4. When you reboot your phone, don't forget to open the app so it will reconnect to the watch. It will still take a few minutes before it starts syncing again. 5. The sleep record is definitely not perfect... It does frequently miss middle-of-the-night wakeups or waking up before the alarm (I can't say if it's any better on the high $ watches, in fairness), but it does seem to be pretty decent. It certainly will at least give you a pretty good idea how good your sleep was.

Great out of the box.
The Dekelife C29 delivers an impressive balance of performance, design, and affordability. At its price point, it exceeds expectations with a sleek and modern aesthetic, robust feature set, and notably long battery life that minimizes the need for frequent charging. Its fitness tracking capabilities and notification support integrate smoothly into daily use, making it a practical companion for both work and leisure. The only drawback I have encountered is a slight delay in the touchscreen’s responsiveness. While not detrimental to overall usability, it is noticeable compared to higher-end models. Overall, the Dekelife C29 represents excellent value and is a compelling choice for anyone seeking a stylish, reliable smartwatch without the premium cost. Will come back after a month or so to update.

You get what you pay for
It's a junk watch but you get what you pay for. If you want a watch that tells time pretty good, although it does lose connection sometimes and then time somehow and I can't figure that one out (very rarely). The battery lasts about 2 weeks is really the best part. and the display is nice and bright and clear. other than that pretty useless the apps don't work and if you try to set it up for calling, it always goes to your watch for calls not just when you want it to.

Works as advertised so far, PITA to set up
Dekelife Smart Watches for Men, Bluetooth Call Military Smart Watch EDIT - October 26, 2025: I had some issues with the watchband. Where the band rubbed, I broke out in a rash and a small blister - both itched. OK, I wore it on the other wrist for a while. Red marks and a small itchy blister developed there as well. So, I took it off and only used it while exercising and sleeping. I have not isolated the cause - allergic reaction, fit, environmental, all or none of the above? I don't know. I replaced the band. The wristband I have now is a Relting Compatible 22mm Replacement Adjustable. Amazon number B0CB7SKXT8. It is stretchy and comfortable, no issues so far. TL:DR – [STILL] Seems to work as advertised, PITA to set up. Operational quirks or operator headspace? Don't buy a smart watch unless you know why you want one. The exercise applications, sleep monitoring, and step count were what I sought. The Dekelife smart watch is light, fairly unobtrusive for its size, and offers several more adult based readable faces of varying complexity. It was on sale when I bought it. The company contacted me immediately after purchase. A nice touch but I have had no contact since. This one has some dedicated linked video based [on your phone] exercise routines. Uh, I don’t do that… but there is a long list of individual exercise types available – run, bike, skip rope, etc. My Montgomery Burns level of “exercise” scarcely registers as such. Oh, well. I am old and cranky, deal with it. Installing an app on my phone, giving it access to all my notifications/locations, and letting it run 24/7 in the background is not remotely appealing to me. I’m retired and nothing I do now is worth noting. For those of you of the windowless rooms, post Benning School for Boys, or up the Little Creek, I wouldn’t. Consult Tio Sucre for guidance. The watch came nicely packaged. Some minor assembly required. Before you do anything, put it on the charger. A USB to proprietary magnetic connector cable is included and only attaches one way. Then, attempt the watchband. It’s not difficult, but it is fiddly. Two additional pins are included, as is a screen protector. Peel the shipping protectors off the face and BACK. Installing the app was aggravating. A slip of paper was included that had instructions in micro fonts. The small QR code was just large enough to grab the link for the software control. Da Fit seems to be the application [Apple or Android]. There is a bit of lag between the phone and watch – particularly when changing the faces. Have a bit of patience, nested VCR programming yet lives, and it’s a long way to the PRC and back. Not everything is addressable on both the phone and watch. The app wants permissions for everything and would not install without letting it have detailed location. OK, not happening. Well, I guess it was happening, but I’ve been on the phone and removing or throttling permissions ever since. So far, no issues. The App is just okay and a bit less than intuitive at first. One of the menu screens is all icons – many are incomprehensible. Having used it for about a week now, the swipe and buttonology is fine. After some random finger-fooling, I have just about figured out where things normally hide and my “favorites” are just a swipe away on the bright, detailed screen. Your phone will show four sets of windows - Today, Class/Workout, C29 [model of phone/some settings], and My [profile and goals]. Icons at the bottom of the screen selects the window and each page has more. All are nominally readable, but who picked the color combinations? I’ll note here that C29 does not show up on my phone in connected devices nor does it show up on other devices as available. The Today window is where most activity occurs. All but a couple of the functions are available at the phone or watch. The phone keeps some cumulative information, mostly on Today. Class/Workout has activity. Touch/swipe around, you may find additional information. Ok, this is what it has been, how I got there. It ran a week near flawlessly. I played with most of the functions to general satisfaction. The step counter is a bit wonky but adequate, the phone provides the time/date base, and the bio-based measurements are decent. The blood pressure measurement was close enough – both against my doctor-provided machine and what the nurse at my cardiologist cited, as was the pulse oximeter and heart rate. I am not a doctor nor do I play one on TV. This is NOT a medical device and state of charge, fit, and movement DO affect the results. Several reading were wildly different from other instruments. YMMV. The sleep monitor function alleges REM. Ok, how do it know? Light sleep versus deep sleep was all that was desired. I have a fitbit clone [the no longer available OCTANDRA Active VeryFitPro, Amazon B07HLJ3GJD] that also monitors sleep. They do not match. In similar fashion, the step counts do not match either. This item seems a bit more accurate or step resolving than the clone. Neither appreciate pushing a grocery cart or toting items as that affects the sensor for step counts. A noted failure. Sleep and step measurements failed. All else seemed to be in order. Grr. What likely happened. I took off the watch to charge and in placing the connector, rubbed the sensor pad on the back with my thumb. The dial lighted, screen changed, several windows passed. Pulled the charging cable, observed the screen, and concluded nothing amiss. Let the watch charge and put it back on my wrist. Bed-o-bye time. Up “early” and in moving about realized – no sleep measurements and zero steps recorded or accumulating. No problem, do a reset and all should be good [right, what’s a cubit?]. Nothing was fixed after the Russian switch was invoked on the phone and not found on the watch [on, off - it’s there, but VCR programming, you know]. As the electron microscope was unavailable, the tiny instruction strip did not yield the secret incantation despite my exhortations. Google was less than helpful but eventually I found a Reddit clue. Finger-fooling around a bit revealed a watch screen that offers restart or reset as options. Restart is a slap in the watch’s chops but reset brings you back to zero. The Da Fit app on the phone has a reset as well – invoke it not or lose your data. After the aforementioned lag, a dash to the bathroom, and thence the kitchen for coffee, steps were counted, all was well. I suspect the sleep monitor will be ready tonight but only tomorrow morning will tell. A search for a manual using terms “great/c29-outdoor-rough-smartwatch-manual” should get you a pdf with limited but helpful information. One miniature page with a number of tiny vignettes and one full sized page. Download, open, and apply your Adobe knowledge to make it readable. Would I buy it again? At full price, maybe not, but at the sale price probably. Your average nine year old can probably have this on its way in moments. Additional comments/possible photos later.
