+# Analog Clock With Abstract Face
+
+## Features
+
+* inspired from the abstract face of the google smartwatch
+* second hand (only on unlocked screen)
+* date
+* battery percentage (showing charge status with color)
+* turned off or swipeable widgets (choose in settings)
+
+![logo](cc_clock24_screen.png)
+
+## Settings
+
+* whether to load widgets, or not; if widgets are loaded, they are swipeable from the top; if not, NO ACTIONS of widgets are available
+* date and battery can be printed both below hands (as if hands were physical) and above (more readable)
+* hour hand can be made slighly shorter to improve readability when minute hand is behind a number
