In 1939, on the occasion of the Swiss National Exhibition, Zurich prepared itself to host a Grand Prix race. But the event was canceled due to the outbreak of World War II. More than 80 years later Maurice de Mauriac teamed up with the Züri Ring Simulation Motodrom and created a timepiece celebrating the perfect illusion of a F1 race in the City. The Zurich GP edition of the Chrono Modern is available in two different sizes (42 and 45mm). Its dial features the racing stripes and offers the choice of a numeral between 01 and 99.
