А в чем разница? Чем так хорош 321 калибр? И зачем было придумывать 861 калибр , а потом 1861, 3861 (если не обращать внимание на коаксиал).
Или 321 - это просто дань истории ?

The constructive similarity of the calibres 321 and 861/1861 cannot be denied. Both movements are considered to be extremely robust and reliable and have proven themselves in space. The central difference lies in the way the chronograph complication works: While the calibre 321 has a column-wheel chronograph, the calibre 861/1861 has a cam/shuttle system for the chronograph operation. The calibre 321 requires more maintenance and is more expensive to produce, partly because of the column wheel.
