My friend has asked me to find out if this part of a rolex movement is a useful part he wants to put for sale on ebay but has no idea on an asking price or if its a /useful part all i know is it has been in his fathers watch bits n pieces for 30 plus years ! most parts are missing ,
If anyone can give any advice it will be appreciated ! i have no idea from what model it is from so here are some photos
Appologies if this post is in the wrong section !!
