Here is a demo and driver for the cheap ILI9152 1.44" Color 128x128 LCD available on fleaBay for around $4.
There are routines to draw lines, circles, fill, and a clock face.
There are both 6x8 and 8x8 character fonts included.
Note setting the time is left as an exercise for the user
Note: The LCD plugs into 8 I/O lines which also provides power and ground to the LCD from P2 I/O pins. The LCD draws minimal current - I've also done this with P1.
