Ladies 9 ct Gold Omega Quartz Watch and Bracelet

Hi
I have a Ladies 9ct Gold Omega Quartz watch for sale.
It is in good used condition.
Please see pictures.
I am selling on behalf of my mother in-law who doesn't wear it.
The battery is flat as it has been sat unused in drawer for a couple of years.
On the back of the watch it says - Quartz 1387 with some symbols.
On the clasp - 791.744 PA and some more symbols.
It comes in its original omega box.
We have been told its worth around £450.
Please email me at [email protected] if you are interested.
Thank You
Allan
