This 1948 Bulova tank is powered by the 17 Jewel Bulova 10BH, which is one of the more advanced movements with precision features such as Breguet hairspring. The case is 10 karat rolled gold plate, with a stainless steel back. The crown has a thick layer of gold on it. The dial has a charming patina, which has been deliberately left untouched to give testimony to the age of the watch. The crystal is brand new, as is the brown calfskin band. With a handsome 22mmx22mm square face, this Bulova is all charm, and is great for both dress up and dress down occasions.
