Vintage 1972 Bulova 1k Diamond “Diadem ‘DR’” Watch

Vintage 1972 Bulova Diamond “Diadem ‘DR’” Watch 28 diamonds totaling 1 carat. The quartz watch is not working, but may just need a battery. I inherited this from my grandmother and am very attached to it. While I'm open to offers, the price reflects some of the sentimental value I attach to this particular piece.
