wristwatch--a design exercise

Problem: design a wristwatch which should be intuitive to use and easy to adjust

We do design two sketches within 15 mins

The first one is a “talk watch”. The watch tells the users what time the local time is every time the users push the only button on the watch. Users don’t need to adjust it, because the local time update by itself, and synchronized to national/international time zones depended on the location of the watch.

The second watch is designed for blind people. The numbers just pop up a little and the blind people can know the time by touch the numbers. For example, the numbers 1,2,3 in the hour circle and 1 to 15 in the minute circle should be popped up if the local time is 3:15. And there is a arrow notch on the watch chain, blind people can know the right way to ware it.
