WS 8: Cleaning the winding parts of a Rolex Caliber 3035

The finished assembled movement was already on the Vibrograf B200 Rob had carried along and he seemed to be very happy with the results of the cleaning. Once I own a timing machine, I will write an article on how to use them. As for now I want you show one last picture of this most pleasant watchmaking day ...

Summary Barrel - Mainspring Oiling

A dry mainspring and some slack had obviously caused the slipping winding. The resistance of the dry spring was too big for the winding system and thus the castle wheel must have disengaged at times and thus given an impression of slipping when manually winding the watch.

The following steps are normally preformed when greasing/oiling barrels and mainsprings. I had found different names for the watch grease suggested. Microtime watch grease from an UK based book, and W -10 Grease from a US based book.

1) Grease the mainspring if it is not being replaced. Although the manufacturers talk about self-lubricating springs, every reasonable watchmaker will still grease them. If the mainspring is made from steel, it is a must. The blue color of the mainspring will tell you whether it is made from steel. Unbreakable mainsprings are normally closer to polished steel in color (like the spring in this exercise)

2) Oil the pivot of the barrel arbor that works at the bottom of the barrel

3) Grease the other pivot that works with the barrel cover

Now the barrel cover can be clipped back on.
