It is an interesting experiment that how can we simplify the elements on the wristwatch. Many great designers already explored this path and they were come up with many interesting concepts. I designed a smartwatch and user interface. I started removing the components like an hour/minute/sec hands, hour markers on the display and then I replaced a single hand with a number on the hand. A hand can show you the minutes and the number on the center can represent the hours that it can be still functional.

A transformation from analog to the digital wristwatch, I was able to remove the multiple hands and replace the simple graphics. It's not a traditional watch face design but it's a straight forward and solid design that has better readability.
It is a simple user interface design that easies to recognize the time. It also has customizable graphics that the end-user can easily change the colors and the hand design.
