It is much more likely that Favre is the common source and supplied to all of them...
With the sales figures of V&C, Ditisheim, Gruen and possibly others it did not make sense for any single company to develop a movement of this kind. With Favre supplying to all of them the combined figures justified the developement and tooling of a movement like this. This is why this system is so complicated to review after 100 years.Who supplied what to whom in which level of finishing.
