Related: Wrist Heart Rate vs a Chest Strap: What Actually Matches
I have logged more than 8,000 miles with a watch on my wrist since 2019, and I test every one the same way: two weeks of daily wear, a GPS trace against a certified course, a heart rate check against a chest strap, and a battery audit at real use. That is the standard I hold a $600 running watch to. It is not the standard I hold affordable smartwatches and fitness trackers to, because they are not trying to be running watches.
Not one of the four devices here has GPS. So the certified-course test does not apply, and I am not going to pretend it does. What I can judge is the stuff that decides whether you keep wearing the thing past February: the display, the water rating, the sensor list, the form factor, and whether the software gets in your way. Those are the differences between a wearable you keep on for a year and one that ends up in a drawer.
Here is the honest framing before we start. If you want accurate pace, distance, and training load on runs, buy a Forerunner and close this tab. If you want steps, sleep, heart rate trends, notifications, and calls on your wrist for the price of a decent dinner, these four are worth a look. I will tell you where each one is honest and where the spec sheet is doing marketing work.
Best Overall: 1.8-Inch HD Alexa Smartwatch (Men's, IP68)
This is the one I would hand to most people. The 1.8-inch HD screen is the largest display of the group, and on a budget watch display size is not a vanity spec. It is the difference between reading a text at a glance and pulling your phone out anyway. Add Alexa built in and Bluetooth calling, and this becomes a watch that handles the small stuff without you reaching for your pocket.
The sensor list is the fullest of the four: heart rate, sleep, and SpO2. IP68 means it survives sweat, rain, hand washing, and a spilled drink. It does not mean you should swim laps in it, and the listing does not claim you can. The 110 sport modes are a menu of labels, not 110 calibrated sports. Treat them as workout tags that organize your history, and the feature makes sense.
Where it falls short is the same place every wrist-based optical sensor falls short. During intervals, when your heart rate swings hard and fast, the wrist reading lags. That is physics and blood flow, not a defect in this particular watch. If you care about accuracy in hard efforts, pair it with a chest strap. For daily steps, sleep, and notifications, it does the job.
Best for Notifications: Women's Alexa Smartwatch, 1.8-Inch
Same 1.8-inch size class as the men's pick, same Alexa integration, same call and notification alerts, in a purple colorway instead of black. If the only thing stopping you from buying the watch above was the finish, this is your answer. The feature set lines up almost line for line.
The differences worth noting: this listing names heart rate and sleep tracking, and it does not name SpO2. If blood oxygen is a feature you actually want, the men's model lists it and this one does not. That is not a knock, it is just the spec sheet being specific, and I would rather read a short list than an inflated one.
Notification handling is the reason to buy it. Call alerts, message previews, and Alexa on the wrist cover the majority of what you check your phone for. For someone who wants a wearable that looks like a watch, fits a smaller wrist, and does not need to be charged twice a day, this is the straightforward pick of the group.
Best for Swimming: Parsonver Smart Watch, 5ATM
This is the only watch of the four that claims swimming, and it is the only one with the rating to back the claim. IP68, which the other three carry, is a dust and water resistance rating for splashes, sweat, and accidental immersion. 5ATM is a pressure rating, and it is the number that covers lap swimming in a pool.
That distinction matters more than any other spec on this page. Most people buy a "waterproof" watch, swim in it once, and find out the hard way that IP68 and 5ATM are not the same sentence. If you swim, this is the pick, and the decision is over. The 110+ sport modes give you a lane for pool sessions and everything else you do on dry land.
The trade-offs are the usual ones for a swim-first budget watch. It is not the biggest display here, and it does not list Alexa or Bluetooth calling, so it is a training and activity tracker rather than a wrist phone. If your priority is water, buy this. If your priority is notifications, buy one of the two above.
Best Simple Tracker: 1.10-Inch AMOLED Fitness Tracker
The smallest screen of the four and, on paper, the best panel. AMOLED at 1.10 inches is a band, not a watch, and that is exactly why it earns a spot. Bands are lighter, they sit flatter on the wrist, and they are the form factor I actually sleep in. If your goal is 24/7 heart rate and sleep tracking rather than a second screen for your phone, start here.
The listing also claims blood pressure monitoring. I want to be blunt about that, because it is the single most misleading line in the budget wearable market. A wrist device at this price is not a blood pressure cuff. If the number moves in the same direction as your actual readings over weeks, it is a trend, and trends are not diagnoses. Do not make health decisions on it.
What you do get is a waterproof step counter, a pedometer that runs all day, sleep tracking, and continuous heart rate in a package light enough to forget. For someone who wants the data without the notification firehose, this is the cleanest fit of the four.
How I judge a budget wearable
My normal review process does not transfer here, and I will not fake it. There is no GPS to trace against a certified course, so the distance test is off the table. What is left is the part most reviews skip.
Display first. Can you read it outdoors? An AMOLED panel at a small size beats a washed-out LCD at a large one for contrast, but size wins for how much you can read without scrolling. Second, the water rating. I check whether the listing says IP68 or 5ATM, because those two phrases get used interchangeably by shoppers and mean very different things. Third, the sensor list versus the sensor reality. Heart rate, sleep, and SpO2 are plausible on a wrist. Blood pressure is a marketing stretch, and I say so.
Fourth, the software. The software is the watch. A budget wearable lives or dies on whether notifications arrive reliably, whether the companion app holds a connection, and whether an update quietly breaks a feature that used to work. Fifth, form factor. A band you sleep in collects better sleep data than a watch you take off at 10 p.m.
What the specs actually tell you
IP68 and 5ATM are not synonyms. IP68 covers dust and protection against sustained water exposure like sweat, rain, and a drop in the sink. 5ATM is a pressure rating, which is what lap swimming requires. One watch here carries 5ATM. Three carry IP68. That is the entire swimming conversation.
"110 sport modes" is a label list. The accelerometer and optical sensor underneath do the measuring, and no budget watch has 110 separately calibrated algorithms. More modes means better organized history, not better accuracy. Anyone selling you mode count as accuracy is selling you a menu.
SpO2 readings on a wrist are useful as a trend and unreliable as a single number, especially if you are cold or moving. Sleep staging on these devices is estimated from movement and heart rate, not from brain waves, so treat the deep sleep percentage as a rough shape, not a lab result. And 24/7 heart rate means sampled, not continuous in the clinical sense.
None of this makes the category bad. It makes it a category where you should know what you bought. Steps, sleep, resting heart rate trends, and notifications are all genuinely useful, and all four of these deliver them.

Should you buy the 1.8-inch HD Alexa smartwatch?
Yes, if you want the most watch for the money. It has the biggest display, the fullest sensor list, Alexa, Bluetooth calling, and an IP68 rating that covers everything except the pool. It is the one I would recommend to a friend who wants a daily wearable and does not care about GPS.
Skip it if you swim laps or if you need accurate pace and distance. It does neither, and no firmware update is going to change that.
Should you buy the women's Alexa smartwatch?
Yes, if the men's model was the right feature set in the wrong finish. You get the same 1.8-inch screen, the same Alexa integration, and the same call and notification alerts, sized and colored for a smaller wrist. It is a sensible pick that does not ask you to compromise on capability for looks.
The one thing to check is SpO2. This listing names heart rate and sleep, not blood oxygen. If that sensor matters to you, the men's version is the one that lists it.
Should you buy the Parsonver smart watch?
Yes, if you swim. The 5ATM rating is the only one in this group that legitimately covers a pool session, and it is not a small detail. Everything else here is splash and sweat resistant, which is a different promise.
You give up the big display and the calling features. That is the trade, and it is a fair one for swimmers.
Should you buy the AMOLED fitness tracker?
Yes, if you want a tracker, not a watch. The AMOLED panel is the best display technology of the four, the band form factor is the one you will actually sleep in, and 24/7 heart rate plus sleep tracking is the core of what this category does well.
Ignore the blood pressure claim, or at least treat it as a trend and not a reading. Everything else it promises, it delivers in a package light enough to forget you are wearing.
