Shinola and city officials gathered outside Cobo Center to unveil the first clock, a 13-foot-tall, pole-mounted timekeeper that is an homage to the city’s Kern’s Clock on Woodward Avenue. The other three clocks, which also went up Friday, are at Eastern Market’s Shed 3, in Midtown at a future dog park at Cass and West Canfield, and at Shinola’s headquarters at the College for Creative Studies.
