Caravelle Digital Crown

[Diamondave]

I have a Caravelle Digital from the 70's that my father gave to me. It is missing the crown and am not sure if the stem is broken. These seem to be hard to find and Bulova was absolutely no help. Can these parts be found anywhere?

Caravelle Cal. 11 OWU 17j manual-wind movement

 

Any help is appreciated.

Caravelle digital.. If you can open the back on the watch one can see what base movement it is.
Usually there is a PUW 561D or a PUW 1561D under the hood.
If you look at the bay you should find an abundance of stems and crowns for these calibers.
I have previously made a small walkthrough with the 1561D, the 561D isn't much different.
