COS-Felix
The crown-operated chronograph goes “Felix”
ChronographCrown-operated (COS)DateAutomatic
The Crown Operation System, short COS, stands for Habring²'s exclusive patented world novelty. It means a chronograph which is operable completely without pushers, buttons or other operating devices. In order to activate the classic stop function the well-known and well-tried crown is sufficient – the crown only needs to be turned against easily felt resistances. With the very own A11 calibre the COS gets “Felix” after 10 years.
