Before you start pulling your 6497's apart to service them a word of warning...it's NOT as easy as it looks in that little animation.
Taking it apart is easy but theres a few things that is not shown.
The barrel is not taken apart to show the mainspring. Servicing of the mainspring is crucial and removing and replacing it requires a special tool.
The balance jewels are not removed on this animation, this is another crucial and often overlooked part of a service, it's also a tricky operation.
When you have it in pieces do you have the right equipment to clean the parts? if you do not then you are wasting your time. If you think you will be doing good putting oil on to a dirty movement, think again. That will just act like a grinding paste and stop your movement.
Do you have peg wood to peg out/polish your jewel holes?
Do you know how to replace the balance [censored] so that the impulse pin correctly engages with the pallet lever?
When replacing the bridges do you know how to check that all your pinions are seated properly, if you do not you can easily end up with a bent/broken pivot.
You should be using a grease on the winding stem, also if you get oil where it is not supposed to be it will 'creep' away and into parts of the movement that could effect timekeeping or stop the watch.
Oh, and don't forget to put a TINY drop of oil onto the faces of the pallet stones, you will need a very steady hand and good magnification to do this properly
Don't put oil anywhere else on the escapement
Just a little insight into what seems like an easy movement to work on
Good luck guys
