It specifically traces the development and relationships between key models and calibers produced by Seiko's two main competing factories, Suwa and Daini Seikosha. The diagram maps the progression from foundational watches like the Marvel, to the creation of the high-end Grand Seiko and King Seiko lines, indicating influences (strong, medium, or weak) between different models and showcasing the intense internal rivalry that spurred innovation in Japanese watchmaking during the mid-20th century.
