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

No - its how to make a tool to do that.. Use the tool like a spanner: rotate the back cover of the watch anti-clockwise to unscrew it, then you'll see the battery.

I thought this was a tutorial on how to open a watch (so I can change the battery). I guess I must be missing something here...

Yeah. I know what a spanner is, but lots of people don't. Maybe you could post a photo of your spanner in action.

Very nice and simple idea .I am always in need of one of these when the batteries die on a watch or when I am working on some of my wind up watches.......beats a small screw driver running into the web of your ( or mine) thumb...(cringing and shaking my hand saying ouch that still hurts)

Wow this is so amazingly clever :O. Can we have pictures of it in action?

That's a neat way of overcoming a problem :-) maybe it would pay to talk about what the problem you are trying to solve is, before going into the "how i solved it" part. and a demonstration of how your spanner works wouldn't be amiss
