there are 60 seconds in a minute , and 360 degrees in a circle.
therefore each second past 12 o'clock would be 6 degrees (360/60) farther in a clockwise direction, the same goes for the minute hand - for each minute it would be 6 degrees clockwise. as for the hour hand, it would be 1/2 degree clockwise per minute or 30 degrees clockwise per hour.

it actually depends on if your going to do it with lines in 2d or use 3d objects - if your using 2d it goes back to how to plot a single point of a cirlce , {keeping in mind however that 0 degrees is directly right or 3 o]clock position } if your using 3d objects it amounts to nothing more than creating the objects and rotating them.

making an arrow head is actually quite hard as you have to keep it pointing out from the centre as it goes round.
