Is there anything special about Rolex’s exclusive Superlative Observatory certification?

 After the Swiss Observatory and Omega’s Master Chronometer were announced earlier, I received a watch friend’s urging to change Rolex’s excellent observatory. replica watches australia Let’s talk about Rolex’s excellent observatory today. Again, the Swiss Chronometer is already a very demanding watch accuracy certification. Even so, there are still many brands that after their movement has passed the certification of the Observatory, they still have to come back and put the movement into the case in their own factory for some strict testing to complete higher testing standards. Among them, Omega is that the movement that has first passed the certification of the Swiss Observatory will continue to be certified by the Observatory.

Back to the topic, Superlative Chronometer is an exclusive certification of Rolex. The words (Superlative Chronometer Officially Certified) printed on the dial of the watch existed as early as 1951, but before 2015, after being certified by the Swiss Observatory, Rolex added testing and adjustment in its own laboratory. Rolex did not Too much emphasis and disclosure of details, so many people just acquiesce that Rolex watches are only certified by the Swiss Observatory. But in 2015, Rolex redefined and announced a new standard for internal testing, the Superlative Chronometer. One of the most important points is to increase the daily error range to ±2 seconds.

What are the latest test contents of Chaozhuo Observatory?

The Superlative Chronometer tests the entire watch installed in the case, just like Omega. The premise of certification is that the movement must first pass the certification of the Swiss Observatory (C.O.S.C.).replica watches

The test content of Chaozhuo Observatory includes 4 points:

1. Watch accuracy test.

2. Waterproof test of the watch.

3. Comprehensive test of automatic winding and power storage performance.

4. Simulated wearing test.

What are the required data for the Chaozhuo Observatory test?

It's a pity that I searched a lot of records for this, but I still couldn't find the specific and detailed data of Chaozhuo Observatory, but there are a few points that can be determined.

1. In terms of accuracy: the daily error range is increased to ±2 second

2. Accuracy test orientation: 7 orientations. This also ensures that it is sufficient for everyday use

3. In terms of waterproof level: the test standard for oyster watches is 10% higher than the official maximum waterproof depth; the test standard for diving watches is 25% higher than the official maximum waterproof depth. In other words, the standard waterproof of 100 meters is actually waterproof to 110 meters. This is also the reason why many watch friends think that Rolex watches can be very waterproof even if they are not diving watches.

In addition, as long as the watch certified by the Superlative Observatory will not only have the exclusive words of Superlative Chronometer printed on the dial, but also a Rolex green lacquer seal, commonly known as the small green card. Also starting in 2015, as long as Rolex watches with a small green card can enjoy a super long five-year warranty. Although many brands today have super long warranty. However, in 2015, there were very few brands with super-long warranty, which can be regarded as a new benchmark for super-long warranty.

But this time it is a pity that I couldn't find the detailed data of Rolex's specific excellent observatory test, such as the specific antimagnetic frequency in hertz, the specific parameters of various tests during this period, and so on.
