The Montblanc WT OT is indeed a very cool watch that is an overall great package.
From what I can say, photos doe not justice. I have seen it in the flesh on another wearer and it looks really cool. I think the best feature is the coloured worldmap and the rotating night disc. Very clever idea.
If there is one think I would change, then I want my home zone at 12 o'çlock and not at 6.
