Tianjin Sea-Gull Watch Factory
Chinese watch manufacturer
A goverment decision
On a Chinese government decision in January 1955 four Chinese watchmakers began with the production of watches. From this has now arisen the world's largest manufacturer of mechanical watch movements, whose production cover a quarter of the total world production of movements.
In 1990 the Tianjin Watch Factory obtained the status of a national company, and in 1992 the Tianjin Sea-Gull Corporation was founded. In the same year the decision was made to stop the production of mechanical watches in favor of quartz watches. Five years later it came to a complete reversal of this decision: since then only mechanical watches are produced.
Sea-Gull makes the most profit on the mass market, but through the skills at the production of tourbillons and chronographs one has gained a growing appreciation. Thus the image of the label 'Made in China' was also indirectly improved. Meanwhile, with watch friends Sea-Gull watches are enjoying a growing reputation as a representative of high-quality Chinese watchmaking.
