As I stated to one guy, I’ll just copy and paste for you as well.
“WatchOS17 requires iPhone update IOS17 or newer. iOS 17 is only available on iPhone XS or newer. Phones that have the A12 Bionic chip. (iPhone XS, XR, and newer.) Unfortunately the original iPhone X and older model phones are not supported by iOS 17. Only series 4 watches and newer are available for the WatchOS10 update. Series 3 and older will not get it. Hope this helps!”
the only way to get the update is to get a new phone. Getting a new watch that’s already on WatchOs10 will not work! Have to upgrade phone models.
