I went through the original footage to get a good look at the watch.
From these pictures we can probably say that it is a Apple watch and that it has a golden color. The color on the pin is black, and the band is white, grey, silvery or beige.
The pin is in the exact place for it to be a Apple watch.
Only Apple watch EDITION have the gold color. I.e it is made of gold.
Only 3 of the gold colored watched has a black middle in the pin.
They cost: 10.000$, 12.000$, 15.000$. And all have a 18 carat gold case.
From cheapest to most expensive:
None of them have a white/gray/silvery/beige band though, which brings us to the custom bands:
Quote from Apples page:
Exquisitely crafted bands and clasps.
Designed to provide a striking complement to the solid gold cases.
Jackson obviously put a lot of money and consideration into this watch, check it out on Apples page:
