Galaxy AI is Hardware-Dependent

Galaxy AI features require Watch 7 hardware — they won't come to Watch 6 via software update. This is the primary upgrade reason.

What Stayed the Same

Display sizes (40mm/44mm)
Battery capacity (300mAh / 425mAh)
RAM (2GB) and Storage (16GB)
Water resistance (5ATM + IP68)
Core health sensors (ECG, blood pressure, body composition)

Worth Upgrading?

Yes if: Galaxy AI interests you, you want better outdoor visibility (2000 nits), or you need the faster processor.

No if: Watch 6 works fine, budget is a concern, or AI features don't matter to you.
