Austrian manufacture Habring Uhrentechnik presents a chronograph watch featuring the innovative COS system. 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 around against easily felt resistances. The advantages are obvious: less drill-holes in the housing minimise the risk of ingress of water; no more possible damages of the usually very exposed pushers; no unintentionally starting or stopping by simple movements of the wrist; no more hard-steering or even completely frozen pushers due to staining; just a Chronograph with the reliability of a simple three-hand watch.
The COS is based on the newly implemented calibre A08 which again is based on the wheelwork of the ETA-family 7750/7760. Additionally the already well known Habring² improvements are implemented: the Triovis fine regulation, Echappement and balance wheel in chronometer quality as well as appropriate decor.
The Chrono COS is presently available in titanium only with ruthenium-coloured dial.
