Typical upgrade cycles for most customers is several years, and Apple undoubtedly knows this. Both new watches are great upgrades from 4, 5, 6, and 7 series. That’s a lot of people who would benefit greatly from the new features of the Series 9 and Ultra 2. 😉
All these improvements for the same price as the original is incredible! If you have a 45mm Series 5, 6, 7 or 8, and need cellular connectivity, the Ultra Watch 2 is a no-brainer
