First appearing in Citizen’s line-up in 1967, the Chrono Master is apart 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.
