For the movements, Bvlgari turned to great makers like Audemars Piguet, Piaget, Jaeger-LeCoultre, and Vacheron Constantin. These watches enjoyed their greatest popularity in the 1950s and continued to be made through the 1970s. Each watch head was different, depending on the decade, and varied from round to oval, octagonal, or square. These watches were produced in very small batches and it is not uncommon to stumble across a unique combination (such as the Jaeger-LeCoultre brick-shaped, link-bracelet version you see here).
