Which is better for running?

Both track GPS runs with heart rate. The Galaxy Watch8 adds MIL-STD-810H shock resistance and sapphire crystal, which holds up better to knocks. The Pixel Watch 3 leans on Fitbit's running and activity insights.

The Galaxy Watch8 has the durability edge on paper: sapphire crystal and MIL-STD-810H shock compliance versus Gorilla Glass 5 and no shock rating on the Pixel Watch 3. Battery life depends on screen-on time and LTE use on both.

Is the Galaxy Watch8 worth the extra?

It isn't extra. At $169.99 at eBay versus $175.00 for the Pixel Watch 3 as of November 4, 2026, the Watch8 is slightly cheaper and adds sapphire glass, shock rating and a bigger screen.

Do both work with an iPhone?

No. Both are Wear OS watches and pair with Android phones, not iPhones.

Which has the bigger screen?

The Galaxy Watch8, at 1.5 inches. The Pixel Watch 3 41mm has a smaller round display in a 41mm case.

Which is better for sleep tracking?

Both track sleep. The Pixel Watch 3 uses Fitbit's sleep and stress tracking; the Galaxy Watch8 uses Samsung Health with sleep coaching. Pick the app ecosystem your phone already uses.

Google Pixel Watch 3 (41mm) Wear OS Smartwatch vs Samsung Galaxy Watch8 Smartwatch

Both are Android-only Wear OS watches at nearly the same price: $175.00 for the Pixel Watch 3 41mm at eBay and $169.99 for the Galaxy Watch8 at eBay as of November 4, 2026. The Galaxy Watch8 is the tougher, thinner watch with sapphire crystal, MIL-STD-810H shock rating and a bigger 1.5-inch screen, and it has far more owner ratings behind it. The Pixel Watch 3 is the smaller, rounder Fitbit-based option with Gorilla Glass 5 and a 41mm case that suits slim wrists. Buy the Watch8 unless you want the Pixel's Fitbit health app and smaller size.

Today the Samsung Galaxy Watch8 Smartwatch costs $5.01 less at its best price.
