This Speedmaster model was limited to 50 pieces. Although it celebrated the 700th anniversary of Switzerland, the watch was released exclusively for the Japanese market. As well as the chronograph function, it
also includes a Moonphase and a perpetual calendar programmed up to the year 2100. It is often considered to be the most complicated watch OMEGA has ever produced in series.
