All "Chronomasters" are "The Citizen" but not all The Citizen is Chronomasters, what defines a Chronomaster? I´m thinkin today. I am aware of the history with "The Citizen" name back in 1995 and the start of "Chronomaster" being on the dial from around 2002. But now we have the AQ4000-xx and some of the A010 without the Chronomaster text on the dial, not to mention the cal 0100 models. Is there som special tuning, just random, export, does any one know?
