Looks like a vintage Molnija movement? I can't speak to there 60s-70s stuff but there current movements are great. I've got a few watches with Molnija hand-crankers in 'em and I love the movement.
I think it depends on what watch it's in (much like the 6497/6498s). Here is a pic of the movement in the Junkers that I have (not my pic):
I have the same movement in the vintage Cali dial Radiomir that I bought from Joshua, but it has a solid caseback, so you can't see it. But from Joshua's pics, it's finished and stamped Rolex. :wink:
And you have not got A clue wether it functions allright?
I say some sellers really must look into comunyties like ours And pump up the prices, Or As soon they see A demand for stuf that before where dump articles!
