Bought for my husband who has a PhD in physics and loves theory of relativity. He thought it was cute, but as other reviewers have pointed out, he was upset that 8 is represented by the letter "e" since the constant e is approximately 2.72. It's a tiny detail, but it drove the physics inside him crazy ;) He took it apart, scratched it and turned it into 2^3. He also thought the idea was cute and liked the watch. Some reviewers mentioned that the band was cheesy and they replaced them. My husband actually really liked the strap because it was simple and not as flashy as many men's watches. He liked its simplicity. I like that the dial rotates instead of the seconds hand. It's a cute idea and a great gift for a nerd :)
