Kinda, with the script. But not the lugs, or the markers, dot track, etc. Those IWCs are straight Patek imitations.
Anyway, Japanese watches of that era were obsessed with imitating Swiss watches (could argue GS still are), so, yeah, not an enormous amount of innovation, but it's about the execution and the small details. I do think those new Citizens are pretty clearly "inspired" by Grand Seiko product of the last decade or two if you look at the cases and dials.
Which you could argue both look very similar to an IWC Calatrava from the same era. Who knows.
