The last of Maria & Richard's initial series of anniversary split seconds chronographs. The anniversary series of 20 pieces was made to commemorate the design coming off the 20 year patent by IWC, and as Richard was the original designer of IWC's famous split seconds mechanism for their Doppelchronograph and Portugieuser Split, this represents the first time he has been able to utilize his original concept. They made 3 different dials all with silver sub dials, galvanic blue, galvanic grey & lacquered brown, and this grey execution is the last piece from the series.
A manual wind caliber with an exhibition back to reveal the mechanics in the prominent split seconds. A piece of horological history, which represents a fabulous journey in the watchmaking world.
