All watch bands are compatible with all Watch series and editions. The size and shape of the connector are the same on all Apple Watches. Apple Watch Series 4, Series 5, and Series 6 come in 40mm and 44mm case sizes, so they're the same. As long as you get the same size for the new Apple Watch, the existing bands should fit seamlessly.
Unfortunately, Apple Watch bands aren't universal. It's essential to measure the length and width of your Apple Watch band to ensure that it fits properly. With the Apple Watch coming in so many different case sizes, it's no wonder people get confused as to which of the different watch bands will fit the watch they have. However, even though Apple Watch Series 4, 5 and the new Apple Watch Series 6 come in slightly different case sizes of 40mm or 44mm, your old bands from Series 3 and earlier will still fit.
Apple-branded sports straps and loops designed to mimic them can usually be interchanged with each other, as long as you make sure you have the correct pairing for the band to connect.

The Apple Watch Series 7 was one of many announcements made during Apple's “California Streaming” event, sharing the stage alongside iPhone 13 and 13 Pro, a new iPad Mini with USB-C charging, and more. If the band is compatible with the following sizes, you can use it with Apple Watch Series 1, 2 and 3, Apple Watch Series 4 and Apple Watch SE. The watch comes in a new case size of 41 mm and 45 mm, moving away from the 40 mm and 44 mm size that has been the standard of the last generations of Apple Watch. In case you didn't know, they're only compatible with Apple Watch SE, Series 4, and newer models.
