How can an entry-level cousin judge the excellence of a famous watch? Judging whether a mechanical watch movement is good or bad and whether it is accurate or not, how can ordinary people prove it if they don't have professional test conditions? -look at the certificate. The easiest way is to see if there are special certificates. These certificates are just like a person's academic qualifications. This is just like an interviewer in a large enterprise. "Schoolmaster Certificate", watch brands usually send them to participate in certification in order to make their brands more competitive, while watches that have undergone rigorous testing will receive special certification, such as Observatory certification, PP stamp, Super Observatory, etc. Let's list some in detail below to point out the direction for beginners.

1) Swiss Observatory Certification (C.O.S.C.)

The most common authoritative certificate in the industry is Swiss Observatory Certification (C.O.S.C.), and the watches that pass the test are called observatory watches. COSC was founded in 1973, and it really began to accept the certification of the Observatory in 1976, which belongs to the Observatory's own income-generating project. Observatories in Neuchatel, Switzerland, Besancon, Glashü tte, Geneva, KEW, England, etc. are being tested. The Swiss Observatory's certified watches mainly meet three aspects, the first is the movement certification, the second is the grinding and antimagnetic certification, and the third is that a single movement meets the certification, not the brand certification. The daily difference of movements certified by the Observatory is between -4 seconds and +6 seconds, which is familiar to COSC certified cousins.

2) Certification by the German Observatory

German watches have always been squeezed by Swiss watches, and German watches have their own certification, which is considered as a very small certification in the industry. But like COSC, at least the accurate certification initiated by German watches belongs to the certification of an independent third party, and they are all tested in five directions, with the average daily error of -4 to +6 seconds, which is similar to the Swiss COS certification.

3) Certification of Rolex Super Observatory

In the Shi Ying crisis, it is no longer possible to satisfy the particularity of famous watches simply by certifying the accuracy of movements. For example, all the movements of Rolex, Breitling and Zhenlishi, which were sent to COSC Observatory for certification, were certified, and the success rate was over 9%. Only some of the movements of these brands, such as Omega, Chopin, Panerai, Tissot and Meidu, were sent for certification. The gold content of COSC's observatory certification is getting lower and lower, so Rolex started its own super observatory certification. They adjusted their movement in 7 directions, simulated the daily shaking by human hands for 24 hours, and the accuracy reached -2 to +2 seconds, which was more stringent than COSC's observatory certification. Certified watches have Rolex's little green brand. According to the new policy, there is still a five-year warranty.

4) Omega-to-Shenzhen Observatory

If you work hard, you will have Europe. With the increasing popularity of COSC certification in the Observatory, Omega-to-Shenzhen Observatory certification was introduced in 214. Omega-to-Shenzhen Observatory test includes eight tests, with many highlights and harsh certification, especially the 15, Gauss anti-magnetic performance test. The high-magnetic test certified by the Observatory is definitely not a gimmick, which is as important as accuracy.

5) Geneva Seal

The Observatory certification is a test of the movement's travel time accuracy. Geneva Seal is the official certification of the watch's manufacturing process, and Geneva Seal is another major identity certificate of high-end watches. The certification is mainly aimed at the movement parts, such as screws, shaft holes, splints and gears, which must meet the corresponding technical standards of grinding, polishing and chamfering. That is to say, a movement without craft polishing can't get the Geneva seal. Vacheron Constantin, Chopin, Patek Philippe, Cartier and other brands have all had the Geneva Seal.

6)PP Patek Philippe Certification

Once the Geneva Seal was the embodiment of the identity of the top luxury watch, with the passage of time. With the development of technology, some brands are not satisfied with the external standards, but need higher requirements, more special certification and seek higher technical standards. At this time, Patek Philippe took the lead in withdrawing from Geneva Seal and adopting its own PP certification.

7) Jaeger-LeCoultre's 1-hour test

Richemont Group realized that it needed its own technical pillar certification if it was to gain a foothold in the world of famous watches like a cloud, so it had Jaeger-LeCoultre's 1-hour test, which was first tested in the master series. Needless to say, the signature of the watchmaker on the inside of the watch case is equivalent to the signature of a luxury car on the engine. The special feature of the 1-hour test is that
