Where can I buy a musical pocket watch that plays the "theme of the musical pocket watch from a little …?

… Dollars more? In the movie there is a pocket watch that plays "Musical Pocket Watch Theme" performed by "Ennio Morricone. I can not believe that nobody I have reproduced it and buy one as a gift for Christmas. If you've already seen one please let me know.

I searched for over twenty years and still can not find. I even sent letters / emails to the Ennio Morricone and Hollywood, but never an answer. If you know a place to do it please let me know. Thank you. Chris
