What is the watch

        the watch detection, it can be regarded as Observatory watch. The Swiss Observatory (The Swiss Offical Chronometer that Control), is a Swiss official Observatory test organization (C.O.S.C.) for the identification accuracy of the watch, watch to watch the qualified testing, it can be regarded as the watch. The Swiss Observatory (The Swiss Offical Chronometer that Control), is a Swiss official Observatory test organization (C.O.S.C.) for the identification accuracy of the watch, qualified watches are often called Chronometer, admire the predecessors of this translation for the observatory table. This word, synthesis from two Greek words, one is Khronos (time), a Metre (calculation and measurement). More than 200 years, Chronometre became " Observatory table " although they are not necessarily to the observatory,
www.24timesale.com, Observatory for inspection,
www.24onhere.com, more not table. C.O.S.C. used to have an important test all the institutions, it does not have any competition, to have a good reputation and won’t get some honors biased movement. These sheets of only qualified or unqualified. The C.O.S.C. certificate to prove your college degree, he meets certain requirements, but does not guarantee you have been through in 20 years, as when you get your diploma hanging in the office, you will not mention the score you get. The table of history in the second half of nineteenth Century, the Swiss chronometer contest every year is amazing. People are participating in the best form, in order to become a great man. Just the quartz surface, its accuracy is not easy to make the mechanical table with a par. Then, in late 60,
sunglasses4usale.com, the Swiss government stopped chronometer contest. By November 15, 1951, the Swiss Watch Association will be accurately described, pointed out that the observatory table must be " make the precise tuning in multiple directions and temperatures, obtained the normal operation of the official certificate of ". The table in the watch detection process, some collectors are in pursuit of high accuracy, the table will be mechanical watch can tolerate 15 seconds each day error is reduced to less than 5 seconds, greatly improves the mechanical precision, however, C.O.S.C. can only accept mechanical table for inspection. The detection of detection and general mechanical watches watches are very different, is not only the accuracy standards, test content settings are also very different, it can from the deeper inner quality to determine the stability of watch watch. The table movement, particularly exquisite material and manual techniques, the daily error between 4 to + seconds; and more stringent requirements in the form of quartz was ± 0.2 seconds to be qualified. C.O.S.C. Geneva in Switzerland, Bill, Lashaode peak three places with the test center. In.
