No point in getting nasty. I had thought it was 1:1 when I bought it as well.
I initially aspired to make mine as close as possible. And I still would love to put in an original movement at some point for my own satisfaction but that is where I give up. In fact, when I wear it I have only gotten negative comments about the aesthetics. And that is from colleagues with fairly substantial watch collections - albeit their vintages are all more established names (Rolex, Patek, Breguet, etc.). In any case, I respect those who pursue the dream as it is a labor of love. After all, you cannot wear it and say with a straight face it is a gen - no one who would care will believe you. And those who don't care about the heritage tend to think it is one ugly watch. Of course I wish I had known this before I spent the $1,000.
And by the way the best way to get to 1:1 is to drop it out of a 2 story building. After all it is 60 years old and has been to war. And a pretty nasty one at that.
