I recently bought an Apple Watch Series 3, it's pretty good only it won't update however my sister's Series 3 does update to WatchOS 8 while mine is stuck at 4.3.2, when I go to General > Software update It says it's up-to-date. Is there something wrong with my watch?
Apple Watch, watchOS 4
Oh yeah, that one is A1554.
My phone is 15.2 (latest update) and the model number of my Watch is MJ3T2DD/A
Oh, then I got scammed. Thanks for the help though I’ll bring the seller a visit soon
That model A1554 is an Apple Watch 1st Generation 42mm which will only update to WatchOS4 maximum,whoever sold you this watch has been less than honest.
To get WatchOS8 your phone needs to be running ios15 or higher.
Check the model number of your watch in the watch app on the phone.
Tap on that m number in the watch app you will see something like A275,that is the model number.
My Apple Watch Series 3 won't update past 4.3.2 while my iPhone X is up to date, the Watch says it's up-to-date.
