So I just came across this article on Ablogtowatch and I don't think its been posted here. Its an article about watch hands design illustrated with just the hands belonging to several well known watch models. I recognised 11 out of the 17 posted (didn't get 1,8,10,12,14 and 17; really ought to have gotten 12.)
Answers at bottom of the article. How did you guys do? (I suspect many would get 100%).
