Jerome my friend, in my case you are wrong in this. I have purchased an iPad Pro (latest model) and an Apple Watch (series 6) within the last 12 months from authorised resellers. Both items came from Apple and with full Apple warranty. In the case of the iPad Pro it came with a 12 month free subscription to Apple TV.
I used Banana IT for the purchase of the iPad Pro, can't remember who I purchased the watch from. Yet they were both authorised resellers.
