I have been a long-time Apple user. I replaced an Apple Watch 9 with this Watch 11 cellular version. There was nothing wrong with the old watch, but I upgraded for various reasons. 1. The better, wider screen, which allows me to view photos and see clear security images anywhere. 2. The better speaker and microphone for better music and clearer phone calls. 3. The 5G cellular and dual band wifi capability with better connectivity, and faster data. 4. All of that with a slightly thinner case.
