Example: if an analog wristwatch is moving from right to left,and the air first strikes at the 9:00 position,the air will not be able to remain attached beyond 4-seconds after 12:00.By the way,the angle at the separation point is 22-degrees.

We must be talking about different things, and I would appreciate your patience in helping me understand what you are saying.
Where does Reynolds Number fit in with what you are saying?
Are you implying that all objects with all reynolds numbers all stall at about 22 degrees normal to the surface?
Surely that is not what you are saying????
