Some very very nice pieces in there mate, great stuff!
Btw my best guess at the first watch:
Early Constellation Deluxe dial and hands off something like an OT2799
Seamaster 14363 case
Late Constellation dogleg 168.005 caseback
Service replacement Constellation crown
Cal 551 movement out of a 168.007 / 14900 or similar
But did it ever existed a deluxe dial with silver indices and hands?
Or was it ever made a dial in solid white gold and this is just patina making it look golden?
It just looks like a gold or rose gold deluxe dial, its not uncommon for the hour markers and hands to end up paginating at a different rate from the dial on these especially if the its been exposed for a while as there’s that celluloid layer on the dial but not the hour markers, I’d guess the case was melted at some point for the gold content and the dial ended up getting saved.

It's a factory prototype snuck out the back door by a technician.
Seriously tho, I like it and see no problem with it. Put togethers can be fun.
What puzzles me: 14363 and 14350 had snap-in case backs. The 168.005 is a screw-in. That must've been some work to make that fit.
