These watches are discussed in this thread

As you can see, there is a third similar watch.
I certainly have doubts about the latest two to surface. In the example you've posted, the chapter ring looks to have been cut in a very amateur fashion in order to fit the date window.
The second watch you have posted looks the most believable and it appears to be owned by someone who works in the industry and is very knowledgeable. Is it possible that the latest two watches were created from various spare parts with the aim of copying this watch, which could be genuine? Or perhaps all three watches are the recent work of the same person?
