Looks like an annual calendar with chrono and minute repeater.... could be the new movement they are going to intrroduce???? one thing for sure, wont be cheap.... Imran...
I have done a quick search of both the Patek website as well as google search, buy couldn't find anything. But then again it is now Friday, which means that it is April 1st!!!!!!!!!!!!!
but I don't think they will ever use that chrono movement (automatic) for such a complicated piece. The movement in the 5960 and 5980 is perfect... but a grande complication will ask for a manual wind
