I have not heard of any updates from Lange regarding this. The old Zeitwerk has instantaneous jumping seconds. I believe one of the original post starter's concern was the minute disc unlock at 56th sec marker. Lange official site still shows the minute disc unlocking at the 56th second marker.
At the mean time I got curious and checked some Zetiwerk Date videos, and wow no minute disc movement, so they did some upgrades. Curious to know if the later normal Zetiwerks really don't have the minute disc "shake".
