http://www.ebay.fr/itm/Breitling-Chrono ... Sw~bFWKPogAccording to SN dating this one 1969 it would encase a cal.11 or cal .11-1 .
Let's read the seller's description and look at the movement shot !
"There does seem to be some wear on the Breitling signed chronograph bridge possibly because a case clamp was missing and movement was rubbing case back. This wear does not have any effect on time keeping function. This model of watch has a gritty feel when winding manually but that is normal" The chrono bridge shows signs of something like a lovestory with a soldering torch (?) ...
And the gritty feel when winding manually is normal ... yes it is , as far as the 2 small wind up wheels #1480-1481 have their upper staff broken,as the #410 winding wheel teeth have been eaten by the clutch wheel ... around 150 € spares to add to the price .
Non original hands, broken crystal , it would be good for parts under 700$ , but not a buy it now for 2100$ !
