WS 8: Cleaning the winding parts of a Rolex Caliber 3035
Yes, I got the color right, that barrel is really pink gold colored. And more importantly, now we see the slack on the inside of the barrel cover and at the bottom of the barrel between the mainspring.
Now it was pretty obvious what had caused the inconsistent winding: the main spring was dry! It needed cleaning and oiling.
Note: Do not simply remove the arbor (the part in the center of the barrel) now! First turn it counter clock-wise to disengage the end of the spring before removing it. We did not remove it in our exercise, I am just mentioning this in case you do. Be careful, flying springs are a nasty thing!
