You have to be nearly spot on, and the originator has to have legal IP (trademark, patent) claims. If they don't patent an idea, and it's just "out there" in the marketplace, it's going to be tough for them to come after you.
IMO, most "legit" homages, aren't infringing, or aren't worth the attention/expense of the original. Your comment about "rep honesty" touches on the reason many despise homage watches.
I know a few people (Chinese and American), who used to work in China. They both said that what we consider "payoffs" are just part and parcel to doing business there. Looks like, times, they are a-changin'.
I think raffles-time sells a hand set, but they're long (~17mm, IIRC- made for larger dials). sk-watchparts sells dials of varying diameters, as do several eBay sellers. You'd have to measure your dial opening and inner case dimensions to know what might work.
I've seen shipping status remain in that stage for ~10 days, to subsequently have the package show up at my door the same day the status was updated. I've found that USPS tracking is wonky lately. Some packages I've received, with tracking numbers on them, don't even show in the system. I woudn't start worrying yet.
The new PO is beautiful, but I still think the current rep (old gen) is beautiful as well.
Not sure I'd want to see the display back, and a rep'd 8500, with all the eye candy glued on.
Sounds like an awesome build.
Curious, where did you source the 2893 compatible dial? I was thinking of swapping in a 2893-2 for a GMT IIc build (currently houses an A2836), but the dial date window isn't even close. Date wheels for both 2836s and 2893s are supposed to be @ 8.85mm. The date window on my dial is closer to 7.7
