Perhaps a good certification process might actually push improvements in the final product?
What if COSC said that from 2015 they were going to decrease their tolerances to -1 to +3 seconds per day? Would that lead to a better, more robust, more accurate movement?
What about if they moved to the Fleuritest and tested chronometric performance on cased-up movements across every range AND intensity of movement with tighter tolerances (currently 0 to +5 seconds) per day?
Maybe then consumers would be happy to pay extra for independent certification? But clearly it has to mean something more than the paper it is print on, particularly if a CHF50 ETA movement can achieve better accuracy.
