Agreed. The date function is a handicap of the Peseux 7001 which the Nomos Alpha movement is based on. It is outdated and clumsy, but Nomos marketing bills it as quaint and charming to have to set the date the long and tedious way. As I mentioned before, such a movement is not in keeping with a watch of that price range. The Peseux is the cheapest manual wind mechanical movement around and so was the default choice when Nomos began.
Some of the older Nomos watches (pre-2008 or 2007 if I recall) do not have the manufacture movement and instead have bought in ebauches used. So this is less desirable from a purist perspective.
The Nomos watches are priced about 2-3x the Stowa Antea (I think one of Stowas cheapest models) so the extra finishing should be a given with the price difference. All that said, I would say Stowa is better value than Nomos considering both use ETA movements (Nomos makes them in-house but the Alpha is based entirely on the Peseux; this does not apply to their other movements which have modules added upon the Peseux design). I like Jorg's service as well, having had experience with his mid-market Schauer brand
Owning both a Nomos (pre in-house) and a Stowa I'd definitely give the edge to Nomos in fit and finish. The Stowa is a hell of a bang for the buck but the Nomos is easily a cut above and justifies it's price, even more so with the in-house movements now.
