Best Smartwatches Under $300 in 2026: Full Features, Smart Price
The best smartwatches under $300 in 2026. Health tracking, fitness features, and smart notifications — without paying $400+ for flagship models.
Smartwatch features that used to require a flagship Apple Watch or Galaxy Watch have trickled down to the $150-300 range. ECG readings, blood oxygen monitoring, advanced sleep tracking, and crash detection — all available well under $300. This price range also includes the sweet spot for fitness-focused watches that do sport better than Apple or Samsung but cost less than Garmin Fenix.
Top Picks Under $300
Best for iPhone Users: Apple Watch SE (2nd Gen, $249)
The Apple Watch SE is the smartwatch recommendation for iPhone users who don't need ECG. It runs watchOS 11, has the S8 chip (same as the Series 8 base), and includes: crash detection, fall detection, emergency SOS, sleep tracking, irregular heart rhythm notifications, and the full Apple Watch app ecosystem.
What it lacks vs Series 10: ECG, blood oxygen sensor (Series 9+), always-on display, and the thinner design. For most users, the $100 savings vs a Series 10 is well worth it. The SE2 essentially replaces Series 7 and 8 functionality at a lower price.
