I managed to the a PAM616 with the new movement JF version about a month ago from Chazingtime. The whole process is a nightmare and I am now on my 3rd watch.
1st Watch the movement would freeze randomly and I lost time very fast. It was quickly replaced.
2nd watch the movement is better but the seconds hand will randomly freeze when i raise it up from my wrist to check the time. It seems to get stuck around the 6-7oclock position and refuse to move until I shake my hands.
3rd watch still being checked by Chazingtime to ensure no problems.
It seems the new movement is very erratic and probably it was a mistake to pay premium for an unproven movement. The new 'features' of the movement does not offset the risk of getting a dud.
... and take some conclusions from what´s being pointed at post #11 & 12#
