This iconic Chinese watch has been ticking since 1958. For decades it was one of the “three bigs”: status symbol items—along with a bike and radio—bachelors were expected to own to be considered eligible for marriage. Dongtai Lu Antique Market has plenty of cheap and cheerful reproductions, but they will break on you in a hot minute. Shanghai Code—a tiny store specializing in vintage Chinese accessories—has the real deal. Die-hard watch collectors will love exploring the little watch shops surrounding the now shuttered Shanghai Watch Factory in Yangpu District.
