Lost Gold Ladies watch

On the evening of 29th September, I attended a show at the Adelaide Festival center, and upon leaving I walked along the Torrens River Bridge towards the Next Generation car park, I then drove to Melbourne Street in North Adelaide and dined with friends in Melbourne Street. When I arrived home, I realized that my watch must have come loose and fallen off my wrist. This watch has immense sentimental value for me and I am offering a reward. It is a gold coloured ladies wrist watch with Diamante's.
