on the scale (which I missed, probablograp too much lured away by the chain...).
The most important point is how Zenith will retain its position in the future. The taks is to develop a successor to the El Primero which basically could redefine the automatic chronograph technically, i.e. without marketing hyperbole just like the original one.That is a huge challenge!
As for the connex: All 36,000 bph movements at Zenith are El Primeros...
