I dunno, I just snagged a POv5 with an ETA for a great price. It just seems to be the most solid of these out there, and I like the "older" features like closed back, painted dial (no wobbly numbers or logos)
I'm gonna slowly franken it, I thought it was the best foundation for that..
I'm in the same boat as you. sold off all my Rolex Franken-reps, going for some Omegas now.
I am not impressed with what the newer reps of these have looked like, so I am after some of the older versions of these two (V5 42mm PO, or an older SMP300). There is one older version of the SMP300 that is supposed to be very close to authentic, and parts to franken these are easily found....
Stilty's rings need a little modification, depending on the case it's going into. I have gotten a few of his, and while they worked fine in the watches that they are in, anyone can make these easily enough...
While MBW's Sub offerings were the best at the time, his 1675 left a lot to be desired. I owned one briefly, here is what I remember about them.
Case too thick, basically a sub case. Dial was too shiny/grainy too!
I'm cobbling parts for a gilt dial now too, got a case and a movement, need a gilt dial and matching hands. I know Yuki sells hands wirh dial combos, you get a set of gilt-ed hands with his gilt 5513 dial. Not sure if it fits ETA though.
