I’m not sure what I should rightly call the title of this section, but here we look at pieces that have many of the characteristics of Duographs, but that have been sold by brands other than Breitling. I would surmise that these watches were manufactured by Breitling and sold as a part of marketing or other joint venture arrangements by the other companies.
Breitling Duograph 762
Examples:
1. Grana 762, serial 609277
2. Lebois 762, serial 6092xx
These watches have both kept the same ‘762’ reference number on their cases, and also retain a serial number that we would expect to see on the Duograph. We also see the Grana and Lebois with the same steel case, pushers, crown, same caseback stamping style, and both utilizing the Venus 179.
While we do not see ‘Breitling’ script on the balance cock for these watches, at least the Grana appears to have work done to remove material where the text would be found.
Breitling Duograph 766
Example:
1. Mervos 766, serial 544×72/669×5
We see other Mervos-branded watches manufactured by Breitling, and with this split-second we see the similarities to other Duograph 766. The Mervos appears to have retained the Breitling stamping for the Duograph (544×72 and 766) on the caseback, but also we faintly see another number, 669×5, which I assume is the Mervos serial. The Mervos uses a similar gold case, pushers, crown, and hands. The Venus 185 movement is double-signed, with ‘Breitling’ script on the balance cock as we see for the Duograph, and the addition of ‘MERVOS’ rather crudely stamped (and with red coloring) onto the chronograph wheel bridge.
Other
I’m filing this one as “other” right now. This watch is branded on the dial as Singer, and Pinterest website text notes that it contains a Breitling movement. My assumption is that this watch actually has the Venus 179 movement, with ‘Bretiling’ script on the balance cock. I have not been able to find any other images of this timepiece.
