I assume you're referring to the Google promotion for the Pixel 8 Pro; here's the text of the promotion again:
"Buy a new Google Pixel 8 Pro up to and including 16.10.23 and get a Pixel Watch 2 (Wifi) in the colour of your choice for free. Register for this from 27.10. to 29.11.23 at
https://reward-promos.com/launch2023 and complete the application form. Please note that the application can only be submitted 14 days after purchase."
If you follow the link, it shows the following information under Reward: "Get reward:
You will receive your Pixel gift between 30 and 60 days after your claim is approved."
It seems that Google takes a little longer to process. However, there is also a "FOLLOW MY APPLICATION" function, where you can enter the email address of the application.
