Tourbillon accuracy
So the upcoming chronometer competitions (which pretty unfairly exclude non-European brands) got me thinking. I read previously somewhere that even though tourbillons are more accurate in tests (they're compensating for position after all), they're actually in theory less accurate on the wrist because the wrist is not static and the tourbillon is simply draining energy from the mainspring without any real contributions.
I guess this would then make the ETA 2824 Chronometer grade the most accurate movement in the world ...
or would it?

Tourbillon accuracy...
Hello Ed. W I personally can not attest to Tourbillon accuracy on the wrist. But, was curious about your choice of ETA 2824 as the most accurate movement in the world. Why this one? ETA 2824-2 Movement with Auto wind removed. Dial side Dial side with part...
It won (with a score of 764) the international chronometer contest for non-tourbillon watches
while housed in a Tissot Le Locle Chronometer in the 2011 competition. Even beating a few tourbillons for accuracy and by far beating any other non tourbillon watch. Under telecharger of the 2009 and 2011 sites you'll find the results in French, although...
Sorry, I did not find that impressive
I browsed the web site and found only 7 participants for the classic in 2011 and a perfect watch would score 1000 points. The surprising news is FP Journe only scored 488 which does not seem to be impressive at all. Does that mean the tests are tough? It ...
The requirements are very rigorous and includes
magentic exposure, shocks, and other things, some of which broke watches so those are only the ones that finished, there's a list of all the participants somewhere. This year there are 31 participants, who knows how many will even finish.
I don't know ...
and am much too tired to search out their norms for testing, how they were determined and whether they make more human (marketing) than scientific sense. We need to know about their standards, how they were set and agreed upon, and have them available to ...
