Our top picks

Most people with an iPhone should get the Apple Watch Series 12. Get the Garmin Forerunner 265 if you mostly run or train, want days of battery between charges, or want deeper training data.

We compared the 46mm GPS versions of each. The Apple Watch is a smartwatch that tracks fitness, and the Garmin is a sports watch with smart features. WeeViews makes the same split: Garmin leads with endurance and data, and Apple with tech integration and health.

The short version

  • Have an iPhone and want one watch for texts, calls, payments and workouts? The Apple Watch Series 12.
  • Run or train a lot and want training readiness, recovery and race tools? The Garmin Forerunner 265.
  • Hate charging every night? The Garmin. Its listing says up to 13 days in smartwatch mode, against up to 24 hours on the Apple Watch.
  • Want ECG, blood-oxygen and hypertension notifications? The Apple Watch.
  • Want a bright, easy-to-read screen outdoors? Both are AMOLED or OLED. The Apple Watch lists 2,000 nits.

How to choose between them

  • Battery. The Garmin lists up to 13 days in smartwatch mode and up to 20 hours with GPS on. The Apple Watch lists up to 24 hours of normal use and up to 38 in low power mode. WeeViews says Garmin’s basic models often get 7 or more days, while daily or near-daily charging is the norm for Apple’s.
  • Training tools. The Garmin gives a morning report, training readiness, HRV status, training status and daily suggested workouts. The Apple Watch gives Activity rings, workout metrics and a readiness score.
  • Smart features. The Apple Watch does calls, texts, Siri and payments best, per WeeViews and the listing. The Garmin lists music on your wrist.
  • Health sensors. The Apple Watch lists ECG, blood-oxygen, sleep apnea and hypertension notifications. The Garmin listing names sleep, recovery and HRV tracking.
  • Phone. The Apple Watch needs an iPhone. The Garmin uses its Garmin Connect app, so check Garmin’s compatibility list for your phone.
  • Weight. The Apple Watch listing gives 39.5 grams. The Garmin listing gives none, and reviewers disagree about it.

What owners complain about

  • On the Apple Watch Series 12: battery that lasts about a day, early software crashes for some owners, and a band that irritated one owner’s wrist.
  • On the Garmin Forerunner 265: syncing trouble, glitchy firmware updates, a learning curve, and a paid plan that some owners dislike.
  • On both: no critical review was visible on either page, so owner complaints are mild. Amazon’s summary for the Apple Watch calls heart rate accuracy mixed.

What we left out, and why

We read two listings and 24 reviews, including the Series 10 page.

  • Apple Watch Series 11. Amazon showed it only as used or “See options” when we looked, so it was not a pick.
  • Apple Watch Series 10. A two-generation-old model that we read for context.
  • Apple Watch Ultra and SE. A different price and size class. Our Fitbit vs Apple Watch guide covers the SE 3.
  • Garmin Forerunner 570 and the Fenix line. Amazon lists them at higher prices. We compared the 265, which is sold new today.
  • Cellular models. A higher price and a monthly plan.

How we researched

On October 14, 2026 we read the Amazon listing pages for the Apple Watch Series 12 (GPS, 46mm) and the Garmin Forerunner 265 (46mm), plus the Series 10 listing that the Series 12 replaces. We read each page's bullets and specs, Amazon's review summaries and the lower-star reviews we could see. We also read WeeViews' comparison of Garmin and Apple running watches and checked Google's top results for this question. AI wrote this guide from that research.

The Garmin listing gave no weight or water-resistance rating, and its reviews pool the 42mm and 46mm sizes. The Series 12 listing is about five weeks old, so it has few ratings and few critical reviews. No lower-star review was visible on either page. The Series 11 was not buyable new from Amazon when we looked. WeeViews compared Garmin's and Apple's running lineups of 2025, so we use it for how the two brands differ, not for specific models.

Prices, ratings and review counts come from Amazon and were read on October 14, 2026.
