Detroit has a long history of making stuff — cars, steel, even popcorn. Now, the city is home to a manufacturing facility devoted to the production of an item not made at this scale in the U.S. for decades: Wristwatches. A Dallas-based company has set up a production line for its Shinola brand of watches in Detroit. Shinola officials say their watch production target for this year is 45,000, to be sold online, at flagship stores in Detroit and New York and at fashion and jewelry retailers and department stores around the country.
