Habring² - “Chronograph COS"

The origin of the Chronograph is Austria! Joseph Thaddäus Winnerl (1799-1889), born in Mureck in Styria, invented in Paris in the year 1831 a separately maintainable second hand and thus the probably first Chronograph in history. Today, more than 250 years later, it is again an Austrian manufacture which introduces the Chronograph into a new era: Habring Uhrentechnik. 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 available in titanium only with ruthenium-coloured dial. What remained is the classic and timeless design of the predecessor which is meanwhile out of stock.
