I have two out of the three you are looking at, and a bit of a thing for German watches, so can make some suggestions.
My two from your list are the Junghans Max Bill, and Stowa Marine. Both are very nice watches, but the Stowa calls to me rather louder and gets far more wrist time.
Beyond your list, from my personal experience, I would also add:
Union Glashütte Panoramadatum
All were inside your budget, except the Nomos which was £1,150. All were bought secondhand.
