Atop Precision Industries builds on 30 years of experience and development. Set up as a partnership by husband-and-wife team Mark Lin and Grace Chueh, Atop Precision began by manufacturing precision parts for the Taiwanese watch industry. As globalization drew away the original manufacturing base, Atop invested in developing a new and unique product: A world time zone mechanism for watches, enabling the user to select all 24 world time zones with a single movement. After 8 years and over a million dollars spent on development, Atop Precision perfected this unique style of watch and began the production of their own Atop Watches, a crowning technological achievement recognized by several international awards. Today, Atop Precision Industries, Inc. is the leading manufacturer for world time watches with direct adjustment.
