2026 comparison
Updated Jan 7, 2026
|Sources: Amazon, ManufacturerGarmin fēnix 8 (47mm AMOLED) vs Google Pixel Watch 4 (45mm)
The Garmin fēnix 8 (47mm AMOLED) is the premium option here, boasting an impressive 16-day battery life in smartwatch mode. In real-world usage, that means less time charging and more time enjoying your adventures. Meanwhile, the Google Pixel Watch 4 (45mm) offers a solid 40 hours of battery, making it a strong contender for daily wear without a frequent recharge. What matters most here is the Garmin's ruggedness and dive-rated design, which can handle depths of 40m. If you're into diving or outdoor sports, this feature could be a game-changer. However, the Pixel Watch 4's brighter 3,000 nits display will shine in more casual settings, making it easier to read in bright sunlight.
⚖️ Weight: 2.58 oz vs 1.29 oz🔋 Battery: 16 days (Garmin fēnix 8) vs 40 hours (Google Pixel Watch 4)🌊 Water Resistance: 10 ATM (Garmin fēnix 8) vs 5 ATM (Google Pixel Watch 4)
