Longines L2.640.4.78.3 Master Collection Marriage

Yesterday I received the following parts from a Longines L2.640.4.78.3 Master Collection Small Seconds watch.
Image
The case was most likely damaged, which is why only this set was available for sale.

Movement: I was relieved that only the winding stem was broken. I replaced it, regulated the movement, and now it runs perfectly.
Image
-Hands: The minute hand was missing. Until the original hands arrive, I've installed a different set.

-Dial: It had to be reduced by 3 mm in diameter.

Thanks
Longines call it L512.x
There are variations of it and they also have 6497.

The entire build cost me only a tenth of the boutique price when someone paid for it at launch.
