Why do you need a watch with 3 hands? How often do you need to know how many seconds are passing? How often do you need to know it's 7:51 rather than just "almost 8". Why not have a watch with just one hand?
This app comes with 2 choices for one handed watches:
24Hours: One hand that takes 24 hours to do a full rotation, Midnight is at the top of the watch, midday at the bottom. There are markings for every hour and half hour. Ideal if you take things slow.
12 Hours: One hand on a normal 12 hour watch face
Just for fun there's a watch face that has all 3 hand:
Dots: A normal watch face but with dots instead of hands
