The phenomena of Japan emerging as one of the most competitive industrial nations in the twentieth century and the general shift of competitiveness to East Asia since the 1980s have been widely studied by many scholars from different fields of the social sciences. Drawing on sources from Japanese, Swiss, and American archives, the historical analysis of this book tackles a wide range of actors and sheds light on the various processes that enabled Japanese watch companies to transfer technology and expand commercially starting in the second half of the nineteenth century.By exploring the case of the watch industry, this book serves to establish a better understanding of the origins of the competitiveness of Japanese manufacturing and its evolution until its decline in the post‐bubble economy (in the 1990s and 2000s).
