Bulova Bulova 6BO

Bulova 6BO is a manual winding mechanical caliber produced by the American watchmaker Bulova. The movement was manufactured from 1953 to 1959 and features design elements that may have originated from Aurore-Villeret ebauches, sharing its underlying architecture with the Villeret 120 variant. It represents a discontinued era of Bulova's Swiss-made mechanical movements from the mid-1950s.
