Indeed, when we speak about a perfect finish, we should avoid your macro pics..LOL
Seriously a big thank for your post, as the question of servicing a watch is a recurrent question, and now, we know and understand why and when the service is to be made.
But what will you say about movements that don't need oil, as silicium movements?
The manufactures preconize for these movements a service each 10 or 15 years...
What do you think, as you spoke about the oil life, but also parts usure...?
