Ebay Authentication help

[jokb]

Everyone, need your help authenticating these pieces.

I've been on the hunt for months now and found these 3 pieces. One is ending soon.

1. Rolex deepsea -http://www.ebay.ca/itm/Rolex-Sea-Dweller-Deep-Sea-DEEPSEA-Mens-Watch-116660-/280936372707?pt=Wristwatches&hash=item41691cd9e3

Everything checks out until he showed me the appraisal which says that the serial is a G as opposed to the V on the watch. Seller has been prompt with responses and willing to do paypal with local pickup. but soon as I asked about the appraisal(this morning) he stopped responding.

2. Panerai Pam 000- http://www.ebay.ca/itm/Panerai-PAM-0...item43b2b13b35

3. Omega Sea master PO - http://cgi.ebay.ca/ws/eBayISAPI.dll?...E:B:SS:CA:1123

I'm willing to go full mile for any of these watches but need authentication help.

Thanks a lot in advance!
