If you are an Android user, then you will love this watch face! Retro Digital Watch Face is a completely customizable, interactive Android Wear watch face. You will be able to change the time, date, and day of the week. You can even add a second time zone and change the time of the hour. The date will be shown in different formats, including day, month, and year. There will be an option to change the color of the text and the background.

To make the watch face even more interactive, you can add an interactive element on the screen. This element can be a button, a menu, or anything else you want. When you tap it, it will do something. For example, it can show you the time or the current day.
