The two launches
- Galaxy Watch 9 — released Aug 7, 2026 · list $379.99
- Galaxy Watch Ultra 2 — released Aug 7, 2026 · list $699.99
- Apple Watch Series 12 — released Sep 18, 2026 · list $399
- Apple Watch Ultra 4 — released Sep 18, 2026 · list $799
Samsung launched 42 days earlier. That mattered in August — Android owners could buy six weeks sooner. Today both watches sit on the same shelves, and the earlier launch says nothing about which one is better. A later launch is not proof of better technology.
Why this comparison is only half a comparison
A watch is not a standalone purchase; it is a companion to a phone. If your phone is already chosen, the other camp's watch cannot pair with it at all — no matter how good it is. So read the price gap the right way: $19 apart at the regular tier ($399 vs $379.99 list) and $99 apart at the Ultra tier ($799 vs $699.99 list) are not "which watch is cheaper." They are part of the cost of switching phone camps.
What is actually worth comparing
How each one measures health. Apple measures often and turns it into scores (heart rate every 5 seconds, HRV, a Readiness score). Samsung measures more things (ECG, body composition, an antioxidant index). Daily body scores point to Apple's approach; the longest feature list points to Samsung's.
Where the money gap lives. The regular models are effectively tied on price; the $99 Ultra gap is where a camp switch actually costs more.
The choice inside your own camp. In the end everyone picks regular vs Ultra within their own ecosystem — that verdict lives in our Ultra vs Regular post: /blog/ultra-vs-regular-smartwatches
What is not worth comparing
Chip names. An S11 and a Snapdragon cannot be swapped into each other's watches, so no benchmark settles anything you can act on. Battery figures, either: Apple quotes hours, Samsung quotes mAh, and the units do not convert. Any article that declares a winner on those two is selling you a conclusion it cannot prove.

Who should buy which
Not changing your phone? This comparison ends here — your real choice is regular vs Ultra, or new vs last generation, inside your own camp.
Changing your phone anyway? Then this table opens: choose the camp by health style (scores vs feature list) and by the $99 Ultra gap. The watch follows the phone.
