How to choose which Apple Watch to buy

Here is a 175-word summary of the key points from the article: The article provides a comprehensive guide on how to choose the right Apple Watch model. With the recent introduction of the Apple Watch SE, Series 10, and Ultra 2, there are now several options to consider. The SE is recommended as a budget-friendly entry-level watch, while the Series 10 offers iterative hardware upgrades like a larger display and faster charging. The Ultra 2 is the premium model, focused on durability and advanced features for fitness enthusiasts. A key consideration is the potential loss of the blood oxygen sensor on newer Series 9, 10, and Ultra 2 models sold in the US after January 2024 due to a patent dispute. Older models or watches sold overseas may retain this feature. The article also covers factors like size, materials, and straps to help determine the best fit. Buying a refurbished or discounted older model can be a cost-effective option. Finally, it discusses the upcoming Apple Watch Series 11 and potential updates to the Ultra and SE lines expected later this year.
