Best Smartwatches of 2025: Complete Buyer's Guide

I wear a smartwatch every single day. Have for four years. I've also worn about 40 different models on rotation for review purposes, which means I have calluses from watch bands and very strong opinions about strap widths. Here's what actually matters.

1. Apple Watch Ultra 2 — Best Overall for iOS Users

For iOS users with active lifestyles, the Ultra 2 remains unmatched. Its titanium case, 60-hour battery life with Low Power mode, and precision dual-frequency GPS make it the go-to for serious athletes and outdoor adventurers. The wayfinder watch face alone — which shows moonrise, tide level, and sunrise in addition to the usual complications — is thoughtful in a way that most tech products aren't. The price is genuinely high. But if you're the kind of person who goes on multi-day hikes or does serious marathon training, you'll use every feature.

2. Samsung Galaxy Watch 7 — Best for Android

Samsung's Galaxy Watch 7 brought meaningful health upgrades: blood glucose monitoring via Advanced Glycation End-products (not direct measurement, but still useful for trend tracking), improved sleep staging, and a slimmer chassis than its predecessor. The rotating bezel is back on the Classic model, and it's as satisfying to use as ever. Battery life is two days with always-on display, which is fine but not remarkable.

3. Garmin Fenix 8 — The Endurance Athlete's Watch

The Fenix 8 is in a different category. If you run ultramarathons, do triathlon training, or spend weeks in the backcountry, this is the only choice that makes sense. Multi-band GPS is pinpoint accurate even in dense forest. Battery life reaches 28 days in regular mode. The dive computer integration is wild — this watch will track your open-water diving in addition to your morning run.
