We can not put time go backwards , but we can put a clock in reverse.
Step 1: Let's get starting...
For this job you will need:
1- A clock with a quartz movement. I've choosen this one because it has no numeric marks.
2- A screwdriver
3- A cutting pliers
Disassemble the body of the watch to get access to the movement and the hands.
As this varies from clock to clock Ieave this step for you...
