Seiko was founded by a men called Kintaro Hattori’s 125 years, making watches from another level for all of this time, and transferring the knowledge from generation to generation.
Citizen got it’s name because of the vision of it’s founders. It was built to supply the demand of the customers of having high quality watches for a price that everyone can afford.
