How to make a spanner to unscrew the back of a watch
Step 1: Photocopy the Back of Your Watch
Step 2: Nail the Photocopy to a Piece of Wood
1) using scissors, cut out the image, leaving an inch of white space all around
2) using small tacks and a hammer, nail the image to a piece of wood, placing the tacks where 2 opposing peripheral slots are shown (make sure the heads of the tacks are small enough to fit into the slots on the back of the watch, and don't hammer them too far in)
You now have a spanner for the back plate of your watch
