On the late side but just to add my POV...
I think you could be happy with any of the watches here. For me, I've got a serious crush on the large 29er but the straps are a just a bit large for me so I'll need it on a bracelet. For the size you're looking at the smaller 29er with the black dial is gorgeous and you could wear it with jeans and a t-shirt ore a suit.
I'm curious why you decided against the Sinn 104.
If you made a decision, please share!
Hope you're enjoying the process.
