Excellent for a smartwatch — Garmin rates up to 18 days on the 45mm and 24 days on the 50mm. Real-world results land lower with the always-on display and flashlight, but multi-day endurance is never in doubt. There is no wireless charging.

OnePlus Watch 2R
The headline strength. The dual-chipset design makes this the longest-lasting Wear OS watch — 3-4 days real-world against OnePlus's 100h smart / 48h heavy / 12-day power-saving claims — and it recharges in about an hour.
Garmin Instinct 3 AMOLED
At $449.99 (45mm) and $499.99 (50mm), the Instinct 3 AMOLED sits in a crowded mid-range, and reviewers are split. It's a tough, gorgeous watch — but the missing maps and older sensors make rivals like a discounted Fenix 7 or the Amazfit T-Rex 3 Pro genuinely tempting.
OnePlus Watch 2R
At ~$229 (often $175-200 on sale) the 2R is widely called the best-value Wear OS watch — it delivers ~95% of flagship functionality and the platform's best battery, against a Watch 2 that costs more for steel and dual-frequency GPS.
