Key points
The three intermediate driving wheels for ratchet wheel (32.083)
must be correctly lubricated with Moebius SYNT-HP-1300 Sans
Colorant. Insuffi cient lubrication could lead to the formation of burrs
or chips and hinder the correct winding of the barrel. Cleaning
would not be suffi cient to remove all this.
(see page 4 and 5).
Due to the movement construction, there are various screw lengths.
To avoid problems at assembly, group identical screws together for
cleaning.
Co-axial Escapement lubrication
See Working Instruction No 40.
