A cheap smartwatch can be a great buy. It can also be a waste of money if it does not do the one thing you need. The problem is that every listing says “best”, “accurate” and “long battery”. So in this guide I will show you what to check on the spec sheet before you pay.
One thing to be clear about first: I have not used the watches in this post. I picked them by reading the brand’s own spec pages. Where I say a watch has a feature, that is what the spec sheet says, not something I measured.
Start With One Question: What Is the Watch For?
Most people buy a smartwatch for one of these reasons:
- Notifications and time: you want to see calls and messages without picking up your phone.
- Walking, running or cycling: you want to track your route and distance.
- Sleep and daily steps: you want a simple picture of your habits.
- Battery that lasts: you hate charging things every night.
Pick your main reason. Then use the checks below to see which watch fits it.
The 6 Things to Check on the Spec Sheet
1. Built-in GPS or no GPS
If you run or walk outside and want a map of your route without carrying your phone, you need built-in GPS. Some budget watches do not have it. If the spec sheet does not list GPS (or “GNSS”), assume the watch cannot map a route on its own. If you only walk on a treadmill, you can skip GPS and save money.
2. Screen type: AMOLED or LCD
AMOLED screens show deep blacks and are easier to read in strong sun. LCD screens are usually cheaper. Also check if “always-on display” cuts the battery. On many watches it does, by a lot.
3. Battery: “typical” vs “heavy” use
Brands often print the biggest number on the box. Look for the smaller print. “Typical use” and “heavy use” can be very different. If you plan to use GPS a lot, look for “continuous GPS hours” too.
4. App and phone support
Every watch needs an app on your phone. Check which app, and check that it works with your phone (Android version or iPhone). With an iPhone, a non-Apple watch can show notifications, but you usually cannot reply the way you can with an Apple Watch.
5. Bluetooth calling
Some watches have a mic and speaker, so you can take a call from your wrist when the phone is nearby. Useful on a bike or in the kitchen. Not every budget watch has it.
6. Water resistance
“5 ATM” means the watch can handle rain, hand washing and usually swimming. It does not mean hot showers or saunas. Some brands say this clearly on their pages, so read the small print.
What Budget Watches Cannot Do Well
Heart rate, SpO2 (blood oxygen) and sleep numbers are estimates. They are fine for spotting trends over weeks. They are not medical readings. If a cheap listing claims blood pressure or blood sugar on the wrist, be very careful. Brands like Amazfit say in their own notes that the watch and app are not medical devices. If you have a health worry, see a doctor, not a watch.
4 Real Budget Smartwatches, Compared on Paper
These are real models sold on the brands’ own websites. The numbers come from each brand’s spec page.
| Watch | Screen | Battery (brand claim) | Built-in GPS | Water |
|---|---|---|---|---|
| Amazfit Bip 6 | 1.97″ AMOLED | Up to 14 days typical, 6 days heavy | Yes (up to 32 hours continuous) | 5 ATM |
| Redmi Watch 5 Active | 2″ LCD | Up to 18 days typical | Not listed on spec sheet | 5 ATM |
| Huawei Watch Fit 4 | 1.82″ AMOLED | Up to 10 days max, 7 days typical | Yes (dual-band) | 5 ATM |
| CMF Watch 3 Pro | 1.43″ AMOLED | Up to 13 days | Yes (dual-band) | IP68 |
Amazfit Bip 6
On paper, this is the all-rounder. The spec sheet lists a 1.97-inch AMOLED screen, built-in GPS with up to 32 hours of continuous use, Bluetooth calling (mic and speaker), and 5 ATM water resistance. It works with the Zepp app and needs Android 7.0 or iOS 14 or newer. Note: the box has a charging base but, according to launch coverage, no cable, so you may need your own USB-C cable.
Redmi Watch 5 Active
This one is about the big screen and long battery. Xiaomi lists a 2-inch LCD, up to 18 days of typical use, Bluetooth calling and 5 ATM. The spec sheet lists a heart rate sensor (with blood oxygen) and an accelerometer, but no GPS. So it suits notifications, steps and sleep, not route tracking without your phone. It uses the Mi Fitness app.
Huawei Watch Fit 4
A slim, light option. Huawei lists a 1.82-inch AMOLED screen with up to 2000 nits peak brightness, about 27 g without the strap, dual-band GPS and 5 ATM water resistance. Battery is up to 10 days max and 7 days typical, and the brand says up to 4 days with always-on display. It works with both Android and iPhone. Before you buy, check how the Huawei Health app installs on your phone.
CMF Watch 3 Pro
From Nothing’s lower-price brand, CMF. The brand page lists a 1.43-inch AMOLED screen, dual-band GPS, up to 13 days of battery and an IP68 rating for water and dust. It has a round face, so it looks more like a normal watch. It uses the Nothing X app.
Which One Fits Which Person?
- You want GPS for outdoor walks or runs: Amazfit Bip 6, Huawei Watch Fit 4 or CMF Watch 3 Pro.
- You want the longest battery and a big screen, no GPS needed: Redmi Watch 5 Active.
- You want a light, slim watch: Huawei Watch Fit 4.
- You want a round watch face: CMF Watch 3 Pro.
Buying in Pakistan: Price, Warranty and Fakes
Prices change often, and they differ a lot between sellers here. So I have not listed prices. On the day you buy, compare the brand’s official store (if it has one in Pakistan), Daraz Mall, and a trusted local shop.
A few things to watch for:
- Warranty: ask who gives the warranty, the brand or the shop. A shop warranty can mean very little.
- Clones: popular models are copied. If the price is far below other sellers, be careful. A real watch pairs with the brand’s own app (Zepp, Mi Fitness, Huawei Health, Nothing X). A clone usually asks you to install a different, unknown app.
- Load-shedding: long battery life matters more when power goes out. A watch that lasts a week is easier to live with than one you charge daily.
What to Check Before You Buy (Checklist)
- Do I need built-in GPS? Is it on the spec sheet?
- Is the battery number “typical” or “max”? What happens with always-on display?
- Does the app support my phone and its version?
- Do I want Bluetooth calling?
- Is the water rating enough for how I will use it?
- Does the seller give a real warranty? Who honours it?
- Does the watch pair with the brand’s official app?
- Does the strap fit my wrist size?
FAQ
Is a budget smartwatch accurate for health?
It is good for trends, like “I slept less this week”. It is not a medical device. Do not use it to diagnose anything.
Will these watches work with an iPhone?
The brands say these work with iPhone through their apps. You will get notifications. Replies and payments are usually limited compared with an Apple Watch.
Do I need GPS if I only go to the gym?
No. If you train indoors, a watch without GPS is fine and often cheaper.
How do I know the watch is not a fake?
Buy from the official store or a trusted seller, and check that it pairs with the brand’s own app. A very low price is a warning sign.
