A few months ago, we brought you the exciting news about the launch of the reissue of the Omega Speedmaster Mark II Co-Axial Chronograph. Today, we bring you the new Omega Speedmaster Mark II Co-Axial Chronograph Rio 2016 Limited Edition, which is the third of the new three Mark II models —other two reviewed here. The Speedmaster Mark II Co-Axial Chronograph Rio 2016 is a limited edition of 2,016 pieces that celebrates the XXXI Olympic Games to be celebrated in Rio de Janeiro, Brazil from August 5 thru the 21st in 2016. While this new watch is almost identical to the Mark II with matte black dial, Omega decided to add three different colored rings to the chronograph counters to symbolize the gold, silver and bronze medals awarded during the Olympic Games. Additionally, the watch features polished center links on its bracelet and a specially engraved case back.
