Tudor Le Royer quartz

[Furbo]

I was checking the drawer with old watches (for parts) at my friend who is a watchmaker and found this sad remains of a Tudor watch.

He doesn't remember when he got it, or what happened with movement.

What parts we have are all in the pics, there are also hands, but no crown.

So what I would like to know is
-what kind of movement did this watch use, can't find info on the net, some kind of ETA quartz ?
-is this the original bracelet? (what remains of it) ?
-is it possible to get original crown for this watch?

Thanks for all the info..
