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

Here is the movement from the rotor side with the removed rotor and winding system. Again you will notice, how clean this heavily used watch movement is after not having been opened for 26 years. This also speaks for a great quality and for appropriate tolerances throughout the movement and parts. If you look at the balance, you will see no regulator. Because Rolex uses the less expensive Mircostella system that relies on screws with star shaped (thus the name Microstella, small star) heads requiring a special Microstella tool for regulating. The small tool is however readily available and not expensive at all, ca. USD 10 in Thailand at the more expensive watch parts shop. Rolex has been critized for doing this. I admit that I am not competent enough to judge whether the decision to use the less expensive Microstella system justifies this sort of criticism.

Seeing that all winding parts were very clean again as was the whole movement (we also had a look at the pallet jewels of the balance fork and again found very little sign of the watch having been in operation for 26 years) the reason for the watch not winding smoothly became more obvious. It was probably simply the mainspring that was laying pretty dry in the barrel. You see the barrel in its pink gold colored compartment at 11 o'clock just above the winding wheel.

Rob removed the "key less" (an old term simply referring to the fact that these clock/watch movements do not need a key to be wound) works and on the next picture you will find a picture of the removed barrel.
