The Breitling Watch Source Forums

I am selling my Breitling Chrono Evolution on ebay and somebody has asked for the serial number for authentication, is this OK to give to them ?

Why, do you not have the papers and cosc cert with it,having said that why not, maybe they want to call Breitling to check it either way can't see it being a problem

If you are trying to sell the watch, especially a watch that is as well faked as the Evo then you should absolutely expect someone to ask for serial numbers, and proof that serials match on warranty / watch and COSC (assuming that you have papers). There are some known fake serial ranges, and ADs can confirm that a serial belongs to a particular model.
