I though it would be good to post some pics of some authentic signed Breitling chrono bridges for future references. Most of the fakes are not done with the same script or font and after working on 100s of these, it is pretty easy to tell the real ones from the fakes. However, there are no guarantees - the fakes are getting better all the time.
Pic 1 is a factory polishing cloth with their original script which was a custom design for Breitling - other script fonts to not match this correctly:
The next 2 pics are signed Venus cal 170 bridges in 2 styles. I think the caps preceeded the script but I am not sure:
This one is a script bridge from a Venus cal 175 and most common but I have seen this one done in caps also.
This last one is the one used in the Navitimer and would be very difficult to duplicate. It was also used on some other Breitling models in the late 50s and early 60s.
The big advantage to buying a Chronomat or a Navitimer is that the cases were unique mostly to Breitling and would be very difficult to remake and sell as a fake.
Hopefully this will help someone avoid a fake in the future. Craig
