 The 7765 does not have the movable stud bridge or else you would be able to do it in a similar fashion as the Russian watch, so we have to do this the old fashion way. 

The first possible solution is to move the position of the hairspring.  You are going to have to do this by prying it up by the collet and slightly turning the collet and reinstalling it.

The second way is to move the position of the roller table.  I would like to try the first option, the second may be over to top of what I can explain using text, and the tools on hand.

The objective is to add slack to the hair spring, because it is running fast.  Conversely you would take slack out it were running slow. 

Let me work on getting a pictorial way to explain this with out having your movement on hand.  We will get it done.
