I like Skagen, and they're a rare example of clean design at an affordable price. I especially like an Ancher model -- the arabic version with leather band for general wear and the baton dial for dress. The Holst with day/date dials combines two things I don't usually like (subdials and day/date complications) but does it in a way that I actually like quite a bit. For me it's not the existence of the complication per se, but the readability of the watch. Unfortunately the Holst is a bit on the thick side, but you can't have everything. Shave 3 mm off the thickness and you'd be looking at a $1000 watch.
There are few odd missteps in the lineup. Their rectangular dress watches have batons in a circular pattern, which is a bit... unusual. They also have a watch that has a month calculation. It's done nicely, but it's an utterly ridiculous feature.
Overall Skagen designs remind me of Baum et Mercier at about 20% of the price, and just little bit more Scandanavian if you know what I mean.
Danish Design watches seem pretty similar; I wouldn't be surprised in they came out of the same company. They almost certainly use the same movements. Ironically the faces seem less Scandinavian to me but what do I know? One of their designs reminds of the famous Swiss railway clocks.
I don't have watches from either of these companies because I focus on vintage pre-80s watches.
