You do not need to spend $400 or more to get a genuinely capable smartwatch. Under $300, you can buy a device that handles notifications, GPS-tracked workouts, heart-rate and sleep monitoring, contactless payments, and multi-day or all-day battery life. The trade-offs versus flagships are usually narrower feature sets (for example, no ECG or blood-oxygen sensor on the cheapest models), smaller or lower-brightness displays, and shorter software-update windows. Based on official manufacturer specifications and published expert and user reviews, the strongest sub-$300 picks are the Apple Watch SE (2nd generation) for iPhone owners, the Samsung Galaxy Watch FE and Google Pixel Watch for Android users, and Garmin or Fitbit models for fitness-first buyers.
[[AFFDISCLOSURE]]
- Ecosystem first—an Apple Watch only pairs with iPhone, and Wear OS watches work best with Android
- Under $300 you often lose ECG, blood-oxygen, or the brightest displays, but keep GPS, heart rate, sleep tracking, and payments
- Fitness-focused brands like Garmin and Fitbit trade some smart features for much longer battery life
What “premium features” actually means under $300
The gap between a budget smartwatch and a flagship has narrowed, but a few capabilities still tend to sit behind the $300 line or appear only on specific models. Knowing which features you truly need prevents overspending.
- Health sensors: Optical heart rate and step counting are near-universal. An electrocardiogram (ECG) and blood-oxygen (SpO2) reading are more selective—the Apple Watch SE, for instance, omits both, while the Galaxy Watch FE and Pixel Watch include them. Read more on what a smartwatch ECG actually measures and how accurate SpO2 readings are.
- GPS: Built-in GPS lets you map runs and rides without carrying a phone. It is standard on nearly every model listed below.
- Contactless payments: Apple Pay, Google Wallet, and Samsung Pay are supported on their respective platforms in this price range.
- Cellular (LTE): Optional on several models but usually adds cost and a monthly plan. See our guide to whether you need a data plan.
The best smartwatches under $300, compared
The table summarizes headline specifications drawn from each manufacturer’s published information. Battery figures are official manufacturer estimates under typical use and will vary with settings, always-on display, and GPS use.
| Model | Best for | Works with | Battery (official) | Standout features |
|---|---|---|---|---|
| Apple Watch SE (2nd gen) | iPhone owners | iPhone only | Up to 18 hours | Crash & fall detection, GPS, Apple Pay, deep iOS integration |
| Samsung Galaxy Watch FE | Samsung/Android users | Android (best with Galaxy) | Up to ~40 hours | ECG, SpO2, body composition, Wear OS apps |
| Google Pixel Watch (prior gen) | Fitbit fans on Android | Android | Up to 24 hours | Fitbit health tracking, ECG, SpO2, Google Wallet |
| Garmin vívoactive / Forerunner (entry) | Runners & multisport | iPhone & Android | Multiple days | Advanced training metrics, long battery, built-in GPS |
| Fitbit Versa / Sense | Everyday wellness | iPhone & Android | 6+ days | Sleep tracking, stress tools, simple interface |
Apple Watch SE (2nd generation)
For iPhone users, the SE is the value benchmark. It shares the core experience of pricier Apple Watches—notifications, workout tracking, Apple Pay, fall and crash detection—while dropping the always-on display, ECG, blood-oxygen sensor, and temperature sensing. Its roughly 18-hour rated battery means daily charging, which is typical for Apple Watches. New owners can follow our walkthrough on setting up an Apple Watch for the first time.
Samsung Galaxy Watch FE and Google Pixel Watch
Both run Wear OS and pair best with Android phones. The Galaxy Watch FE includes ECG, SpO2, and body-composition estimates, with the fullest feature set reserved for Samsung Galaxy phones. The Pixel Watch layers Fitbit’s health platform on top of Google’s software and also offers ECG and SpO2. Either can flag an irregular rhythm—see how smartwatches detect AFib.
Garmin and Fitbit for fitness-first buyers
If tracking is your priority, Garmin’s entry models offer detailed training data and multi-day battery life, while Fitbit’s Versa and Sense emphasize sleep, stress, and simplicity. Both brands are cross-platform, working with iPhone and Android. Their trade-off is a lighter app ecosystem and, on some models, no LTE. New to structured exercise?

How to choose the right one
Battery expectations deserve extra thought, because rated hours vary widely between a daily-charge Apple Watch and a multi-day Garmin. Our battery-life comparison breaks down how the brands stack up, and these tips help stretch any watch further.
Frequently asked questions
Can you get an ECG-capable smartwatch under $300?
Yes. The Samsung Galaxy Watch FE and recent-but-prior-generation Google Pixel Watch both include ECG functionality and often sell under $300, though ECG availability can depend on your region and paired phone. The Apple Watch SE does not offer ECG.
Are budget smartwatches waterproof enough for swimming?
Most models here carry water-resistance ratings suitable for swimming, but ratings differ, and “water resistant” is not the same as “waterproof.” Check each device’s specific rating before submerging it—our guide to water-resistance ratings explains what the numbers mean.
Will a cheaper smartwatch still get software updates?
Generally yes, but budget and older models tend to have shorter support windows than current flagships. Before buying, check the manufacturer’s stated support policy so you know roughly how many years of updates to expect.
Do I need cellular (LTE), or is Wi-Fi and Bluetooth enough?
For most people, a Bluetooth/Wi-Fi model paired with a nearby phone is enough and avoids a monthly fee. LTE mainly benefits those who want to leave their phone behind for runs or calls. See our LTE vs. Wi-Fi explainer for details.
