(Apologies to those who read Pistonheads, I'm cross posting it from there) Since the original Ebarhard' are about £3000 I don't think these are the real McCoy... but these replicas on E-bay certainly look good. Do a search on Ebay for "ferrari 4 chrono" and you'll see them listed. http://i13.ebayimg.com/03/i/01/8b/b4/28_1_b.JPG (NOTE: I have no connection with the sale or anyone related to the sale)
check out Forzacollections on Ebay. Sold many Girard-Perregaux watches. Good feedback. Ships worldwide. Extremely good prices.
