**Citizen Eletronic Cosmotron** This was the transition period from the mechanical watches to the Quartz revolution. In 1966 Citizen launched its first ‘electric’ watch – Japan’s first electronic watch in fact – which incorporated what was then new technology to replace the traditional mainspring to drive the movement. Although such a hybrid approach had been introduced years before, Citizen claims this to be ‘the world’s first genuine electronic wristwatch that has adopted a moving-magnet type balance motor, driven by transistor on the regulating device’ The Cosmotron production run was short, about 10 years in all...after it, regular Quartz era take its place here u can read little more about all this: [https://sweep-hand.org/the-x8-cosmotron/](https://sweep-hand.org/the-x8-cosmotron/) This model is with cal 7800 and works nice Movement is interesting, for quick shift of date you hold watch 12h marker face up (like you willnormal hold watch) and to change day hold watch with 6h market up 😊 (upside down😊).
