OK, so started going through some. Sorry this is a bit brief - working off of dial up and there are rather a lot!
In addition to what I stated earlier I always want to see good shots of the dial, caseback (preferably in and out) showing serial and model numbers and movement shots. Buying without a movement shot is taking an absolute gamble - there could be anything in there.
In the first one there are a number of obvious problems - firstly the logo on the movement and caseback is script and on the dial it's block - that just wouldn't happen. With experience you will also learn to recognise that the script logo is just 'wrong'. It also doesn't help that there's another name on the caseback

The look of the dial is just wrong as well, as are the hands. Oh yeah, and I don't like the case.
I guess that the second one is marginally better as at least the logos are consistent, but you can see that the logo on the dial looks to have aged differently to the rest of the dial - and don't you think that dial is in remarkably good condition for a 60 - 70 year old watch? The case style is not Breitling like and Breitling didn't use silver for their cases. Model and serial numbers are also wrong.
The third one has the potential to start some serious debate - there is still a lot of disagreement in the community about whether Breitling used Landeron movements - I've never seen a real one, although I have seen some fairly convincing documentation. This one is never going to cause that debate though, because it isn't a Breitling. The lack of logos on caseback and movement is concerning, but not an obvious problem on its own. However, look at the script logo on the dial and compare it to a real script logo - they aren't identical - the B is the most obvious. Gold plating is obviously also brand new.
Next one - clearly also brand new gold plating, and a Turkish language Breitling????? Model number is wrong and the font is not quite right for the block Breitling, the script B is also wrong.
Next one - well, you can probably tell by now that the script logo is wrong - it looks stretched from B to I and then scrunched up through t, l and i. We have no movement photos so that's a no-no, but the seller claims it's automatic. There were no automatic movements with this layout until the 1970s, and this isn't trying to be from that era.
The last one (other than the one that we did earlier) actually doesn't look too bad. I'm not an expert on these time only automatics but I can't actually find anything wrong with it. I wouldn't buy it because it's in South America, and unfortunately some of their fakes are getting good. I can't place the model number, and don't like the way that it's engraved, and I can't see a serial which worries me, but not as obviously wrong as the others.
