The Breitling Watch Source Forums

Have a friend who needs to sell his Bentley Motors with a blue face. Im sure watch is real he has all box, papers and original sales receipt, and all numbers match. Watch was purchased from an AD in January 2006, purchase price was right around 7200 or 7400. Watch just came back from Breitling about 4 months ago, watch has not been worn since. My price to buy is $4900.00. I m pretty sure this is a good deal any thoughts?
