There is something about the design of this one that always brings cheer whenever I see a picture of one, especially when the photos are well done like this one.
After Lange, UN are my favourite watch makers. There are similarities in that they both have long, fascinating histories which were interrupted and then reborn. Both too are very underestimated, except by those who know. I like that about them as I like to go against popular opinion myself and I like also that they draw much less attention than, say, a Patek and a Rolex.
