Well, Garmin wants you to believe you need to drop $400 to get a GPS that doesn't lie, and Apple wants you to think you need a miniature iPhone on your wrist. I've been wearing cheap watches on every run since 2019, and I'm here to tell you the truth: picking a smartwatch ain't about the logo, it's about knowing what you actually need before you hand over your card.

My name's Eli. I've logged over 8,000 miles with a watch on my wrist, and I've got a spreadsheet that tracks which ones lie about heart rate and which ones just die after three months. I work at a garden center, so I'm on my feet 10,000 steps before I even start training. My dog Gus has napped on more watches than I can count. I've bought four watches in the $17 to $40 range in the last two years, and I've learned exactly what separates a good one from a paperweight.

Here's my framework. It's not a spec sheet. It's a filter.

First, does the GPS match my known 5-mile course? I've run it hundreds of times. If a watch tells me I ran 5.4 miles, it's wrong. If it tells me 4.8, it's wrong. I want the truth, not a flattering lie. My chest strap doesn't lie about heart rate, and I compare every watch against it. A 10 to 15 beat error isn't a small thing. That's a health data problem.

Second, does the battery survive real use? If I have to charge it more than once a day, it's a failure. My ritual is plugging it in when I shower every morning. 15, 20 minutes tops. A watch that can't survive that is a paperweight.

Third, is the app going to make me want to throw the watch across the room? An app that's annoying to use will kill a good watch faster than bad hardware. I've spent two hours fighting a Bluetooth connection that was holding onto an old watch. I almost gave up. But when it works, it's great.

And fourth, would I wear it for a marathon? That's the real test. Not a quick jog around the block. A 26.2 mile grind where every mile matters.

Here's how that framework played out across the three watches I've got in rotation right now.

MorePro (B0GJSXGKG8)

Let me start with the one that surprised me the most. I bought this for $25 because I needed a backup and I've had good luck with MorePro before. The version I own is the basic model, and honestly, I'm blown away by what it can do for the price.

The GPS is the weak point. I ran my known course and it told me 5.3 miles. That's a 6% error, which is outside my acceptable margin. For a $25 watch, I expect that. For a marathon training cycle, I'd be annoyed. But here's the thing: the heart rate monitor is shockingly close to my chest strap. I averaged 158 on my chest strap, and the MorePro said 161. That's a 3-beat difference, which is fine for most training.

The battery is where this thing shines. After a full day and night of wear, it still showed 82%. That's the dream. I charge it when I shower and it never drops below 70%. I've had it for two months now and it still charges fine, which is more than I can say for some watches I've owned.

The app is called DaFit, and it's the weak link. The QR code on the watch doesn't work. You have to find it in the manual. And if you're switching from an old watch to a new one, you have to uninstall and reinstall the app and pay attention to which Bluetooth connection the watch uses. I've figured this out through sheer stubbornness and digging through reviews. But once it works, the app gives you an incredible amount of health and activity data that's easy to understand.

The band makes my wrist sweat something fierce. I swapped it for scrunchie bands from FTYQUEE and my wrist stopped sweating. That's a $7 fix, and it made a huge difference.

For $25, you get what you get. And what you get here is pretty good. The GPS ain't perfect, but the heart rate is honest, the battery is solid, and the price is right. I'd recommend it if you're just starting out and don't want to spend a lot.

Garmin Forerunner (B0CT3SGHXL)

I've worn a friend's Garmin. It's nice. It's also $400 plus. I can buy several of these cheap watches for that price, and honestly, they look almost identical. But I'm not going to pretend the Garmin doesn't do some things better.

The version I tested was my friend's Forerunner, and I wore it for a week of runs while he was on vacation. The GPS accuracy is the best I've ever seen. I ran my known course and it told me 5.0 miles. Exactly 5.0. My chest strap said 158 average heart rate, and the Garmin said 157. That's within my acceptable margin, and it's the closest any watch has come to matching my strap.

But here's the thing. The battery life is worse than my cheap MorePro. I got about five days of use before I needed to charge it. My MorePro goes a full day and night and still shows 82%. The Garmin has a color screen and a bunch of features I don't use, and that eats battery.

The app is better. I'll give it that. Garmin Connect is intuitive and gives you all the data you could want. But it's also overwhelming. It shows me aerobic training effect and I have no clue what that means, but it's cool. It also shows me training status and recovery time, which is nice if you're a data person. I'm not. I want to know my steps, my sleep, my heart rate, and I want to take calls without digging my phone out of my apron pocket.

The price is the killer. $400 for a watch that does maybe 10 times more than my $25 watch. But I don't need 10 times more. I need accurate GPS, honest heart rate, and a battery that lasts. The Garmin does all three, but it costs 16 times as much. If this watch lasts me six months, that's about 14 cents a day for the MorePro. The Garmin costs 30 times more and does maybe 10 times more. I'll take the cheap one.

I'm not saying the Garmin is bad. It's the most accurate watch I've ever tested. But it's not 16 times more accurate. It's maybe 2% more accurate. And that 2% isn't worth $375 to me.

Apple Watch (B0FQF5BZ8Z)

I had a friend let me borrow their Apple Watch for a week, and I wanted to love it. I really did. But I couldn't get past the battery.

The version I tested was the latest model, and it died every single day. I'd take it off the charger at 7 AM, and by 10 PM it was at 15%. That's a full day, sure, but I'm used to my cheap watch going a full day and night and still showing 82%. The Apple Watch made me paranoid about battery. I was checking the percentage constantly. That's not a fitness watch, that's a anxiety machine.

The step tracking is fine. The heart rate is close to my chest strap, maybe 5 beats off. The GPS is accurate, too. I ran my known course and it told me 5.1 miles. That's within my acceptable margin. But none of that matters if I can't trust it to last through a marathon. I ran a 20-mile training run with it and it was at 20% when I got home. I had to charge it before I could even take a shower.

The app is smooth. I'll give it that. Apple Health is easy to use and gives you a ton of data. But it's also a notification machine. I kept getting buzzes from emails and texts and calendar reminders. I don't want that. I want a watch that tells me my pace and my heart rate and lets me take a call if my mom calls. I don't need to know every time someone likes my post on social media.

The price is absurd. $400 plus for a watch that dies in a day. I could buy four of my MorePro watches for that price and have a backup for every day of the week. And honestly, I'm not sure four times the value exists.

I think the Apple Watch is fine if you're already in the Apple ecosystem and you want a mini iPhone on your wrist. But it's not a fitness watch. It's a notification machine with fitness features bolted on. For a runner, that's not what you need.

How to Actually Choose

Here's the thing. I've been doing this for seven years, and I've learned that the best fitness watch is the one you'll actually wear every day. Not the one with the most features on paper. Not the one that costs the most. The one that you don't have to think about.

Choose the MorePro if you want a cheap watch that tells the truth about heart rate, has a battery that lasts, and you're willing to fight with the app once to get it paired. It's a solid starter watch, and the price means you can buy another one when this one dies. Because it will die. The battery dying at three months is the single most common complaint across every cheap watch I've looked at. My first one did it. So did the one I bought as a gift. Plan for it.

Choose the Garmin if you're a serious runner who needs the most accurate GPS possible and you're willing to pay for it. It's the best fitness watch I've ever tested. But it's also 16 times the price of my cheap watch, and it doesn't do 16 times the work. If you're training for a marathon and you need to know your pace to the second, it's worth it. If you're just trying to get your steps in, save your money.

Choose the Apple Watch if you want a smartwatch first and a fitness watch second. The battery is the dealbreaker for me. I can't trust it through a marathon, and I don't want to charge it every day. But if you're already in the Apple ecosystem and you want to take calls and check notifications, it's a fine choice. Just don't call it a fitness watch.

I don't track prices day to day, so I won't pretend to know next week's deals. But I know what I'd buy right now. For the price, the MorePro is a steal. It's not perfect, but it's honest where it counts. And that's more than I can say for watches that cost 16 times as much.

My bottom line is this: buy the cheap watch, see if you actually wear it, and upgrade if you need to. You get what you get, and for $25, you get a lot. [Check price on Amazon] for the MorePro if you want to see for yourself. I've been wearing mine for two months and I'm still blown away.
