COSC info about Rolex accuracy

[ron17402]

I posted the following article about COSC in an earlier thread about the accuracy of Rolex vs. ETA.

There were many comments (debate) about which movements are the most accurate.

I'm not sure how many of you actually read the article, but it makes several mentions about what we are talking about. For example:

COSC has three testing facilities. The overall failure rate between all three and all watch movements is 4.5%. However, the Geneva laboratory tests almost exclusively Rolex movements and has only a 2.2% failure rate. In Le Locle where almost no Rolex movements are tested has a failure rate of 5.7%.

Your figure out which watch movement is the most accurate relative to COSC facts.

Also, the chief of COSC made the comment (while drinking wine with the author) that the Rolex 2235 movement is by far the most consistently accurate movement ever tested.
