Dufonte Diamond and Ruby Womens Watch by Lucien Piccard

We just finished cleaning out Aunt Mary's house and found this beautiful watch. Dufonte's Diamond Collection by Lucien Piccard. Never worn and still in the original box. As you can see in the photo's it had a $250.00 value (years ago) and has diamonds and ruby's. I think it needs a new battery. This is a very elegant thin gold (?) watch. Thanks for looking and may God bless...
