I wonder why you would care about the movement? If you take the back of anybody who has seen a real Rolex movement would see the difference right away - no matter if you have the one on Trusty's or King's pictures
sorry I don't think that you could take your 196 to an AD without it being identified as a replica fast...the bezel of you case just looks very different from the real thing or earlier 196's
The IWC...yes and if you keep posting pictures you are forcing me to buy one
here are some closeups of the concentric circles on the subdials
You can also find my pictures here on RWG @ IWC Portugieser Silver with Black Subdials
Here is a pic scanned out of the 2004 IWC catalogue/book and as finepics already pointed out the gold markers should be PG/RG and not Yellow Gold - it also shows that the Panda does exist.
cheers
