The Tianjin Seagull Corporation
The Tianjin Seagull Corporation was established in 1992 and is based in Tianjin, China. However, its roots trace back to the mid-20th century when the Chinese government initiated projects to develop domestic watch manufacturing capabilities. One of these projects, Project 304, aimed to create a Chinese-made chronograph wristwatch for air force personnel in the 1960s. The Tianjin Watch Factory was assigned the task of developing and producing this air force chronograph.
Chronograph Development
As part of their efforts to create this chronograph, Tianjin Watch Factory purchased machinery and designs from the Swiss Venus company, specifically the Venus Calibre 150 movement. They then upgraded this movement to create their own 19-jewel ST19 movement, which eventually became the foundation for the ST1901.
ST1901’s Historical Significance
The ST1901, based on the ST19, became a significant part of Chinese watchmaking history. The movement successfully met all the requirements and passed various tests, leading to an order for 1,400 of these watches for the Chinese air force in 1966.
Establishment of the Tianjin Seagull Corporation
Fast forward to the early 1990s, and the Tianjin Watch Factory was promoted to a national-level enterprise, leading to the establishment of the Tianjin Seagull Corporation in 1992. The “Seagull” brand, initially known as “DongFeng” or “East Wind,” had already gained recognition internationally as one of the first Chinese watches to be exported. This name was retained when the new corporation was formed.
