In my opinion that watch is a fake. The numbers other than the 711 make no sense when it comes to a vintage Breitling. The 'Breitling' on the movement bridge has been added and isn't original along with the Breitling inscribed on the case back. The big issue is that the case is much larger and the wrong shape as pictured in Richter's guide. The 711 I had a few years ago was a tiny watch measuring about 30mm and I had it on a Bund strap to give it a little more presence on the wrist. The movements were used by a number of different brand names and they were all very small watches so not that rare. I don't remember the movement type but I think a Venus 196.
