I see a lot of Breitling Chronomat watches on ebay, but I am wary of buying them. Can anyone attest to legitimate sellers? I am looking at one watch that was posted for sale by two sellers at the same time (europeak23 and watchpros01us). same serial number, just different bezels. Sounds kind of fishy to me. Difficult to hand over $4000. ANyone ever used Paul Duggan a retailer out of Boston with an online business?
