In 2003, Omega did https://www.iwmontres.com/Collection/ingenieur/ a collab with Japan's oldest department store, Mitsukoshi. Limited to 300 pieces, this "panda" style Speedmaster (ref. https://www.iwuhren.de/ 3570.31) has kind of a cult following. In fact, it was https://www.cuhren.de/produkt-Sammlungen/santos-de-cartier/ one of the Speedmasters I thought about the most back in the day. People even made aftermarket dials to have similar watches since prices on the Mitsukoshi LE have now gone sky-high. That can make finding a correct example rather tricky.
