concealed

That's my greatest fear.  He seems reasonable, but is obviously [censored] because the local shop told him it was not original.  Granted it, it is not on the original strap and it is a rare older model (painted sausage dial, slimmer crownguard, etc), but come on, it has the correct swan neck regulator, matching serial number / authenticity card, etc.  Just frustrating!

That's my fear.  Thanks gentlemen.  I really hope the buyer is rational, I have already offered him a partial refund to avoid the hassle and done the legwork to find the authorized repair shop/AD in his hometown.  

Hey Guys,

I recently sold an E Series PAM 111 that I am certain is authentic.  The buyer did not like the scratches that were on the crystal (which in fairness to him, I didn't overtly disclose, but I thought they were consistent with age and wear), so he took it to a local shop in a mall in Manila that is claiming that the item is not authentic.  Mind you, this is not a large operation, it is a very small kiosk in a mall, not an authorized dealer by any means.  

Here is the eBay listing: http://www.ebay.com/itm/Panerai-PAM00111-111-Engraved-Grafitti-Mvt-2002-Series-E-Painted-Dial-RARE-/282377495955?rd=1  Do any of you think that this is actually fake?  Had it for a few years, never had a problem, has a matching certificate and all correct period E Series details (smaller CG, swan neck regulator, painted dial)...

I have advised him to take it the local repair shop affiliated with Lucerne (a large dealer) http://lucerneluxe.com/watch-care-service/ and am waiting to hear back.

Such a drag for me!  Any advice would be helpful.  Thanks gentlemen.
