Those hands seem rose gold to me, and winning a small lottery is easier than finding Omega hands, let alone rose gold
5022 is the same story, I suggest Sternkreuz ATCR 296 - it was suggested to me by a forum member as well to test, I haven't tested it yet, but inspected it, and it seemed like a good substitute
You can message me for the rose gold hands if cost isn't an issue, I could part with a crystal as well
My honest suggestion is to just flatten and repaint the hands - it won't be noticeable since paint will hide the small flaws, and ATCR 296 seemed good, the ring/depth measurements seemed very compatible
