Sorry for the evidence, but the more I dig in the Fifty Fathoms topic, the more I discover things, and sometimes mysteries.
A few weeks ago, I discovered a watch which may represent THE missing link between the Milspec and the Tornek.
The Milspec, you all know it:

The Tornek :
Now, let's see how this missing link is looking like:

Exactly the same case, lugs, the same big crown we find on the Civilian Milspec, and the same writing we find on the Military Milspec.
The Case back is almost the same than on the Milspec, with one exception:
Instead of the engraving Blancpain Milspec at the center of the case back, you have here a small inscritpion:
AM ( I don't know what it stands for ) and a 2 digits number XX.
But the dial ( with the exception of the writing ) and the hands are the same than on the Tornek Rayville.
Even the bezel is the Tornek Rayville thick one!
Don't know how to call it:
A Transitional Milspec?
A Pre Tornek?
A Pre Teaser, maybe, as a Review on the Tornek is in the Tube!
But in any case, a real nice watch, whose interest is due to its part of Mystery.
Enjoy!
Best,
Nicolas
