I think you need to replace those parts, right? From a cal 1337 maybe? I found a diagram of a 1330, it is probably the same family as the 1337, also I believe a bit smaller. The pieces you show look to me very similar to pieces 9022 and 9051 shown here. It´s not much I know, as I couldn´t find any technical specs for the 1337, but if you do understand this message then hopefully it could possibly help a bit, if indeed that is what you were asking about in the first place of course
The part to the right is a Sliding pinion . But not sure what the left part is . The movement is a Omega 1337 . Hard parts to find . Maybe you could buy a watch that is not working on Ebay ? For parts . The sliding pinion you could buy at https://www.cousinsuk.com/category/omega-movement-parts .The parts name is OME13329101.
