IIRC correctly, early Breitling movements were not always signed, and this movement is early given the absence of shock protection. So the movement could be from a Breitling.
However, as mentioned above, the dial is badly repainted. There are many signs for someone who is accustomed to looking at dials. However, there is one incredibly obvious signature of a repainted dial, that anyone can see here, even if they are not an expert. Perhaps the OP can simply look closely at the dial and see what he notices.
