The diagnostic imaging Casey looks at says it was taken in 2012, but the paperwork with it says his date of birth is 1979 and his age is 42. In 2012 when this paperwork would've been printed, he would've been 33. 42 is the age he currently is in 2021.
The watch Casey inherits from his uncle is supposed to be a rare 1965 Rolex Double Red Sea Dweller.
This model never existed as the Double Red series debuted in 1967.
The watch pictured is not a Sea Dweller of any kind but a Submariner type 16610, which is a very common model produced from 1987 to 2010 whose market value is less than tenth of that for a Double Red Sea Dweller.
After a high speed fall with a head injury like that, Casey would have been made to get a medical checkup straight away.
