Rolex watch handset

Hello I’ve been looking at some Rolex handsets online and have been very surprised by how much they are going for, I have a selection what came in a box of bits and bobs which turned out to be a great deal, I’m wondering if I should take these to a dealer, but it would be better if I found out what watch they are for before I do.
This looks like what I’ve seen described a luminous & it looks like yellow gold, this looks like it might be a submariner but think many use these kind of Mercedes hands.
