Well, recalling the requirements, it seems that the Junghans fits a little better. SS bracelet and closer to a minimalistic dial. Nevertheless, I would picked the RADO Centrix Jubilé in its automatic version. Less expensive than the NOMOS and bitter higher than the Junghans, this $2k watch is comparable to the TH Carrera you've showed in your first message - IMHO, even higher quality, better materials and a true minimalistic and modern design. The MOVADO Museum has also an automatic version (Red Label) that is nice!
Of course, as psychologists use to say, we make our choices from the heart firstly, and then, create logical arguments only to justify ourselves.

I wish you all the best in this so special moment!

Cheers!
