No, that's a silver dial, not MOP. Any dealer can get a very decent one with that dial, I believe. Just send them a picture and ask.
I don't know about the polished mid links question but I've never been too concerned about that. There are soooo many different DJ's and there's no reason that a gen owner couldn't swap out the bracelet. It's not really a tell.
The expensive part of the franken is the white gold bezel. They are now going for close to $300. JMB has made some pretty awesome SS smooth bezels from what I've seen. Maybe you could contact him and ask him about building you a custom DJ, If he's interested, I'll throw in the gen dial for next to nothing and you could come out way under $800 I would think.
