What is this 16700? A Frankenwatch?

The watch is likely not a "Frankenwatch", it is probably a watch that has sustained use and damage that required the replacement of these parts. The only place you can get a service case is at an RSC.

Without the paperwork for that service you will not have the original serial to reference an approximate original build date. However, that is kind of irrelevant since the only thing left is whatever movement parts that were not replaced.

Yes nothing wrong at all with service parts watches per se imho, just 50-60% of orig. watch price my offer-park eg c £4.5-5K...or so, not the fig they are asking.

Btw OP they will increase in value dependent on model eg a 1601/1603 only a bit slower than orig pieces to a lot slower on sought after units....
