HELP me indentify my DOXA watch

[NikaPika]

I know that in my family we have a vintage DOXA watch.
We couldn't find it for many years and today my mom found it.
I remember that my granfather told me that we have to take care of it because it's a vintage and expencive watch..
I went to many forums and pages about Doxa watches but I can't find what kind of watch model is mine.
I cleand it and the frame appears to be 925Silver. It have a clasp. In there is a crown and it says Doxa 0.800.
1 cm down is engreaved another crown and on the left side of the crown is like a half moon.
It has also a serial number and down it says "R".

Can someone please tell me what kind of watch is this? And how much is it worth?

I may be crazy but i'm affraid to take it to some modern watch center so they can look in it...

I'm afraid that there is not a lot of information available about vintage Doxas, including the pocket watches. You may want to inquire about this one in the Vintage\Pocket Watch Forum. Those guys are quite knowledgeable.

Good luck,
