Apple Watch vs Garmin
A mainstream smartwatch vs an accessible running watch — compared on battery, GPS, training and smart features.
Apple Watch and Garmin are the two names most people weigh when they want a real fitness watch, but they were built with different priorities. To compare like with like we put Apple’s mainstream pick, the Apple Watch SE, against Garmin’s accessible running watch, the Garmin Forerunner 165. Both have built-in GPS and cover the fitness basics well; the gap is in what they optimize for.
The Apple Watch SE is a true smartwatch first: a huge app library, calls and payments from the wrist, Crash and Fall Detection, and tight iPhone integration — at the cost of roughly a day of battery and no ECG or blood-oxygen sensor. The Forerunner 165 is a training watch first: a bright AMOLED, all-systems GPS, structured workouts and recovery tools, up to eleven days of battery and no subscription — but far fewer smart apps. Crucially, the Apple Watch is iPhone-only, while the Garmin works with iPhone or Android. Below is the short answer, a side-by-side matrix, and who each watch suits.

Frequently asked questions
Is the Apple Watch or Garmin better for running?
For pure running, the Garmin Forerunner 165 is the stronger tool, with deeper running metrics, structured training plans and up to eleven days of battery. The Apple Watch SE tracks runs well and adds a huge app library, but its roughly one-day battery is limiting for long training blocks and races.
Does the Apple Watch SE work with Android?
No. The Apple Watch SE requires an iPhone and does not pair with Android phones. If you use Android, the Garmin Forerunner 165 is the better choice here, since it works with both Android and iPhone. Match the watch to the phone you already own.
Which lasts longer, Apple Watch or Garmin?
Garmin wins clearly on battery. The Forerunner 165 lasts up to about eleven days in smartwatch mode, while the Apple Watch SE lasts roughly 18 hours and needs daily charging. If you want to track sleep without charging around it, Garmin is the more practical option.
Does the Apple Watch SE have ECG or blood oxygen?
No. The Apple Watch SE does not include an ECG app or a blood-oxygen sensor; those are reserved for higher-end Apple Watch models. The Garmin Forerunner 165 also lacks ECG but does offer Pulse Ox (SpO2). For cleared ECG, see our health-monitoring wearables guide.
