What is how do i know what series my apple watch is?

To determine which series your Apple Watch is, you can follow these steps:

1. On your Apple Watch, tap on the Settings app (it looks like a gear icon).
2. Scroll down and tap on "General."
3. Tap on "About."
4. Look for the model number. You can either use this number to search online for the specific model, or compare it to a list of Apple Watch series model numbers to determine which series your Apple Watch is.

Alternatively, you can also check the packaging or receipt from when you purchased your Apple Watch, as it usually specifies the series. Additionally, you can use the Apple Support website and enter your serial number to find out more information about your device.
