vintage waltham platinum ladies watch

I have a Art Deco style platinum case with approx 26 diamonds ladies watch. It has a black canvas strap with a small chain. Its a 17 jewel movt and the serial number is 2471...to my understanding this is one of the earlier watches that the CO. made. Production year is 1855. It is a wind up watch and is still in working mint condition with no scratches on the crystal and no missing stones. There is no paperwork or box with this watch.
