Apple Watch S7, S8, and S9 are the product names for three generations of Apple Watches. However, I can't provide a product difference between the current S8 and S9 because Apple has not released a watch with the S8 and S9 models at this time (at the time of writing). Apple typically launches its products each fall, so it may take until then to learn the specific differences between the S8 and S9. You can always browse Apple's official website or follow the technology news to get the latest product information.


The Apple Watch S7, S8, and S9 differ in several ways:
