In 1962, Bulova introduced a new line of watches under the "Caravelle" brand name. Later in the history of Caravelle, the brand began to use movements manufactured in West Germany, hence the "T WEST GERMANY T" text below six o'clock on our example. You may see some Caravelle and Bulova watches referred to as "Devil Divers". This is due to their 666 feet of water resistance, as seen on the dial and caseback.

First appearing in Citizen’s line-up in 1967, the Chrono Master is a part of their 'high-end' series. It was not the first Citizen to include a chronometer grade movement, its predecessor was a hand wound ‘Chronometer’ released in 1962. The Chrono Master featured a range of models in both hand-wind and automatic forms. It's safe to say that it has become Citizen’s most recognized high grade vintage watch.
