Bulova 1926 5728
The case is 18K solid gold in excellent shape with 8 faceted saphires, 2 at each corner of the crystal, and there is a saphire crown. The case measures 14.36mmx25.01mm and weighs 4.2 grams including the fixed wire lugs and the saphires.
The hinged case only has an 18K stamp in the back and numerous jewelers marks. The watch is currently missing the crystal and I am having a vintage filigree band with saphire stones repared to match with this beauty.
The movement is currently running but gaining so needs a good cleaning. One variation from the advert is this movement is 15 jewels and the ad is listing 17 jewels.
The ad is a 1925 from the DB.
