Picture on metal

I seem to gather impossible projects to my workroom but now it´s more
than before.

How to make picture permanently stay on nickelpalted pocketwatch?

My aim is to product one pocketwatch with picture of my dear wife.
And maybe later more of them as friends find what i´ve done.

Maybe some day even bigger pics on big aluminium plates I have available.
