I am very sure it is a Platinum Day Date. It is a president bracelet, which is not used on the Datejust, and from the pictures it looks like the day field is also there. Just my 2 cents.
Agreed at first glance it looks like a datejust but close up she seems to be wearing the
platinum presidential. You can see the day field.. maybe she wanted a change up from her
daytona..
