Seagull

Seagull (海鸥) is the brand of the Tianjin Watch Factory, now Tianjin Seagull Watch Group, which built China's first domestically designed chronograph movement in 1963 under the classified "Project 304" using tooling bought from Switzerland's Venus. It remains a major mechanical-movement manufacturer, supplying calibers to other brands while selling its own watches, including the reissued 1963 chronograph, under the Seagull name. (Wikipedia)
