Deep Dive Comparison
Design & Comfort
The Apple Watch SE 3 has a 44mm aluminum case and weighs 32.9 grams. The Forerunner 165 has a slightly smaller 43mm fiber-reinforced polymer case but weighs 39 grams. Apple is 6.1 grams lighter, while Garmin’s round case looks more like a conventional sports watch.
Both can handle swimming and everyday water exposure. Apple lists water resistance to 50 meters, while Garmin rates the Forerunner 165 at 5 ATM.
Battery Life
Garmin wins by a huge margin. The Forerunner 165 is rated for 264 hours, or 11 days, in smartwatch mode. The Apple Watch SE 3 lasts 18 hours, or about 0.8 days, so daily charging will be part of ownership.

The gap remains large during recorded workouts. Garmin promises up to 19 hours of GPS use, while Apple lists 7 hours. Either watch can cover a typical run, but Garmin is the safer choice for long races, travel, and weekends away from a charger.
Health & Fitness Features
Both watches include optical heart-rate sensors and single-band GPS. The supplied specifications do not include controlled accuracy results, so neither watch gets an accuracy win on paper.
Garmin adds SpO2, a barometric altimeter, compass, thermometer, accelerometer, and ambient light sensor. Apple answers with a temperature sensor, compass, always-on altimeter, high-g accelerometer, high dynamic range gyroscope, and ambient light sensor. Garmin’s stronger battery and longer GPS runtime give it the practical edge for repeated training.
Smart Features
The Apple Watch SE 3 is far better equipped for use away from a phone. Optional LTE, Wi-Fi, a microphone, and a speaker support a much broader smartwatch role. Its 64GB of storage also dwarfs Garmin’s 4GB.
Both watches support NFC payments. The provided specifications do not confirm offline-music or notification details, so those features should be checked against the exact model and phone before purchase, especially because Garmin sometimes separates music capability by version.
Price & Value
The Apple Watch SE 3 launched at $249, while the Garmin Forerunner 165 launched at $249.99. That $0.99 difference is irrelevant.
At those prices, Garmin delivers more value for runners because its 11-day battery and 19-hour GPS rating affect every week of ownership. Apple gives iPhone users more smartwatch hardware for the money, including optional LTE, calling hardware, Wi-Fi, and 64GB of storage. Street prices change, so compare the final checkout prices rather than assuming either watch still sells at launch price.
