Bulova 1977 La Petite

Clean ladies watch with N7 dated 10k RGP case.  White, oval shaped case with "butterfly" lugs and 2 diamonds for accents.  Silver dial background with black, roman numeral indices all around.  Basic black hour and minute hands, no seconds hand.   I probably missed it but did not see a match to this one on the site.  

Bought this recently as part of a "lot" that also included 2 very nice 70's era Bulova boxes and a 2nd 1960's watch.  I wanted the boxes and honestly wasn't expecting much out of the watches.  To my suprise they both run and are keeping decent time over the last few days.

Thanks for any info!
