Swatch Packaging idea

The idea for my Swatch packaging is to have the watches in a secret compartment notebook, this is because the concept of the watches is doodling so the notebook would essentially be a doodle book with a secret compartment. The watch would come inside the notebook, the idea is to make it look like a notebook that can be doodled in. The front of the notebook will have the shape doodle on it which will give an indication of the watch design inside.

I now need to figure out how to make the secret notebook.
