This caliber has not been made for several years and was replaced by calibre 1530-1575. There are however substantial numbers of movements of this type still used today and in some early production models a correction is advisable.
The sole for self-winding mechanism, part #7005 with us made of brass, and the reversing wheels, part #7018 also brass, provide a bad friction surface resulting in signs of excessive wear.
This problem was remedied in the course of production and the great majority of calibre #1030 movements have a steel sole spacer, part #7005-1. This part which is available from Rolex Material Division is inserted over the sole and provides a complete solution to the problem.
After having added the sole spacer, it is necessary to readjust the endshake of the intermediate rotor wheel part #7021 since it will have been increased by an amount equal to the thickness of the spacer.
