I my little investigations and researches at Panerai and at the Marina
Militare, it resulted that none of 3646 have
unmarked dial or unmarked movements at least and specially those pieces destined
and delivered to Panerai or the Marina Militare.
Rolex verbally said that if they delivered other 3646 they should have signed movements.
Within Italy
and Switzerland, this far I never found any traces of the unmarked dials and or
movements.
My Vintage Panerai interests has always been about the Marina Militare pieces,
but I also know that a few, other 3646 do have unsigned movements and or dial,
only a part from
aknowledging
those other pieces, I never and I have yet not found any supports for those pieces.
It appears and
seems that those few unbranded like-Panerai-Radiomir-dial and California dial
with unsigned movements were all delivered to the German market, by who, how
and the whys to me remains a mystery.
You say 'Many Cali 3646 did NOT have Rolex signed movements or casebacks'
- To help me understand your ‘Many’, I need to ask you: How did you come to this; Do you have supports achieves.
