MMMD
·5. The correction of the day. It cannot take place between 9 ans 12 AM [9 UHr and 12 Uhr in the German version] and between 12 PM and 2 PM [24 UHR and 2 Uhr] since at this very moment the pin driven in the hour wheel double toothing is in the path of the day driving finger which is lifted when operating the correction.
