Hi, I have, among others in a drawer, a project watch for this ref (I'll probably finalize it when I'm retired and have enough time.......).
Let me show you how it assembles, mixing pictures of the project (without dial) and of a donnor of the same ref (with its original dial) :
The case is composed of three parts in which the caliber R17.8 will be placed.
from above :
and from below
The caliber goes inside the caseback :
and is maintained by the ring :
Then the caseback is closed by the crystal (you may see inside the broken stem -I used the donnor caseback for the next two pictures which exlains why there is no stem tube...) :
then the two parts are assembled :
Of course before inserting the caliber in the caseback, it needs to be fitted with a dial, hands and a broken stem. Here they are (picture of the donnor tat I will, one day, maybe, use to complete this project) :
I have noted on a tag a ref 2339 for this model, but I can't remember where I fuond it, so I am not sure it is the right one.
