You can change every aspect of how the clock looks, from colors to the shape of numbers, and even add your own background image. The widget is resizable, so you can make it as big or as small as you want. The clock can also display the date and battery level. You can have multiple widgets with different timezones. There's a working second hand that can optionally be turned off. You can set clock as a live wallpaper that will also be visible on the lock screen.
