Some watches just grab you because they are so far from the norm. They change the way you think about time and how you interact with your watch. For me, these are the ones that really stand out. A single hand sweeping the dial instead of the usual three hands. A single hand 4-hour watch that breaks your day into bold chunks. An annual calendar that only needs to be adjusted once a year. A 24-hour watch that puts the whole day on the dial and makes you see time in a completely different way. Which one would you pick for your collection? Pics are not mine... I want, but do not own these complications.
