Automatic mainsprings and barrel wall

[superg3]

Hi all,

First excuse my bad English.

I just ended the level 3 course and by the moment I spent most of the time trying to find watch flying parts in my room....

My questions are:

1- Automatic movements like Citizen 8200A or Seiko 7S26A I tryed to fully wind but it never ends, ¿ is it normal?

2- Before to start disassembling watch barrels I want to be sure to have the correct libricant for the barrel walls.  I have Moebius 8300, 8200, 9010, 9415, D5 and MOLYKOTE 50; ¿any is valid for barrel walls?

Thanks in advance,

Marcos-

The automatic spring will never feel completely wound as it will slip if to much is collected around the arbour. I use D5 on the barrel wall.

You need a braking grease, Moebius 8217 or Kluber P125 are two general ones that work well. Regular greases will slip too soon and diminish the power reserve of the watch.

Thanks for your answers!!!

Perhaps I don’t use D5. Away from home and could not look at the jar?
