If you are referring to the eighth generation of smartwatches in general, then they are the latest iterations of wearable technology that offer a variety of features such as fitness tracking, mobile notifications, music control, and voice assistants. Gen 8 watches may also have more advanced health monitoring capabilities, such as blood oxygen saturation and electrocardiogram measurements.

If you are referring to a specific smartwatch model called “Gen 8 watch,” then I am not aware of any such product as there is no standardized naming convention for smartwatch models across different brands and manufacturers.
