Brand Watch News Report: Forum timezone the following three issues in the most common: how good my form? Its value is really worth it to pay me money? Also, I was not crazy?
Since the existence of a number of shortcomings, there is the identification of organizations to watch provides some criteria.
Mark than the Geneva Observatory in Switzerland a little proof of popularity (The Swiss Offical Chronometer Control), is tested by the Swiss official Observatory Organisation (COSC) a high degree of accuracy of the qualified watches, watches for the accuracy of any test, often called a qualified watch of the Observatory watch (Chronometer), the pricing of a factory than an ordinary mechanical watch a 1,2-million more than high (ie, a movement to use the same.)
In watch technology, the collectors in pursuit of high accuracy, mechanical watch chronometer to fifteen seconds per day tolerable error is reduced to less than five seconds, greatly improve the precision of mechanical watches, however, is the world's chronometer Any brand mechanical watches can apply test (reportedly 70 Seiko invented the quartz watch was sent to COSC testing, the results are the first branch support ..., so high accuracy is strictly prohibited from quartz watches to the test).
60,70, OMEGA has the most chronometer, present, Rolex has the largest number of observatories watchs (each watch are the Oyster chronometer), Patek Philippe watch is a small number also have the Geneva Seal Observatory certification (such as Sky Moon Tourbillon 5002) brand. However, the brand has a chronometer with the Geneva Seal, but the brand than many too many, and as such, the Swiss Observatory watches worth raising certification helpful, but not a good form is not absolute.
The truth is: the watch is sent to the Swiss movement for precision testing Observatory, who can test the accuracy of the movement through the dial marked in the form of words Observatory - Chronometer, while the new form will normally be purchased with a certified Swiss chronometer cards, inferior race proved the inherent movement of the watch passed the test.
Myth:
1 COSC no error
think this is wrong. Anything, there will be errors, not to mention the mechanical watch, COSC movement also exists such a problem, the standard error of the current room COSC -4 / +6 In other words, the standard speed of movement every day to be in this range , not more than 4 seconds slower, not faster than 6 seconds. As a general rule, the new watch movement COSC error will be smaller, and my own hippocampus is +1 / day, a friend of 15200 is -1 / day.
2 COSC does not make sense
Most of this view put forward a better understanding of friends watch and know the real top brands, such as PP, VC, AP every year there is little movement through the COSC certification, leading to the conclusion, COSC does not make much sense. I would like to COSC in the Swiss watch industry in the global watch industry even has its significance for both, and the reason that top the watch by PP that is a small number of COSC and its brand positioning, yield related. Imagine tens of thousands of pieces every year watch, and most rely on hand-made watch how to talk to an annual production reached 700,000, with a laser tuned Rolex compared to what. The durability of the movement from the precision on the Rolex, it became the king of COSC from a side note the significance of the COSC.
3 COSC is the highest standard
Anything without word "most" one said. Play watch friends know JLC, it has its own standards of a test - Master 1000 小时 movement test. JLC not go to the COSC competition, but it's 1000 hours less than fully certified the accuracy of the movement COSC, and even some friends of the relative ratio of COSC and 1000 hours of testing methods, the latter for the watch factory after the stability and accuracy more meaningful. I do not have the opportunity to try JLC, but many players know the reputation of the JLC Master 1000 hours of precision is remarkable.
4 COSC very high difficulty
May be a number of years ago, in that each needs its own design and manufacture of factory assembled an age of movement, so that their movements to COSC standards developed by a certain degree of difficulty, then, today, the core system provided in the ETA, the COSC is no longer difficult to match the height. ETA without any piece of polished core system, as long as the patience of watchmakers can be tuned to COSC standards (of course, not polished, not replace the balance wheel and hairspring core components of the system can long remain COSC accuracy is a problem) . So today COSC Swiss precision movement is no longer the absolute selling point. No agent has the magic to you talk about when COSC can one ear into an ear out.
5 COSC prices
Eventually pulled out their real money to buy the watch, the price factor is of course one of the most important factors. As sent to the Swiss watch factory certified Observatory agencies requires a certain cost, and manufacturers and would not not return to improve this part of the cost of production, so the final cost of COSC certification will be counted upon in the buyers, in general, COSC movement and not through the same movement COSC compared to the price will go up about 30%. And if you will be more money out of the 30% of the total is that you own.
