I can't find one specifically for the 611...but DR Ranfft's webpage lists the following as movements in the same family.
My guess is that you might get lucky and find a lubrication chart for one of them that could be applied to all the movements.
Maybe start with the 600 ??
manual wind:
600: Reed's regulator
601: excenter regulator
602: excenter regulator, chronometer
610: Reed's regulator, date
611: excenter regulator, date
613: excenter regulator, quickset date
Hope this helps somehow !
