I don't know why it is called KW version.
KW doesn't make this model
The watch on this SV is a Puretime version with the last PT modifications included: movement screws chromed instead of blue and the CP chromed instead of Gold (like old PT batches)
See a little bad fitting between decoration bridges, three "jewels" in the bridge @9 and narrower "R" on LUMINOR inscription in comparison with "R" on PANERAI
DECORATED MOVEMENT A6497 LIKE A PANERAI P.3000 – see inverted layout
No doubts this is a Puretime version with the last modifications included
KW version doesn't exists
