Brief introduction to “Dong Feng”
Tianjin Watch Factory formed a research team in 1965 and started to study the structure and technical parameters of over 140 watches made by Switzerland, Japan, Germany, France, Russia and other countries. The strength and weakness of these watches were listed, calculated and analyzed. Several new design drafts were drawn, submitted to experienced watch makers and sister companies for comments and suggestions. In August 1966 trial-produced ST5 movement, 27mm diameter, 3.8mm thickness, power reserve 44 hours, time keeping accuracy within 30 seconds per day. Dong Feng was highly praised by consumers due to its reliability, bigger front face, nice-looking appearance.
“Dong Feng/Eastern Wind/East Wind” is the predecessor of Sea-Gull. Ever since 1973 “Dong Feng” disappeared after a short life span less than eight years.
