This is my first Timex Electric
And this is the second, I finished to service last night.
I dismount all the pieces to wash all and then I rebuild and oiled.
This is a good article of my friend Fabrizio on 'how to":
I know that the Serivice manual for these electric movements says that we don't need to take all apart, but as for the manual movements I think it's better.
If you think to the age of these watches you know why!
