Having been to the Fleurier Quality Foundation I was impressed by the rigorous nature
of their testing protocol. It is as good as it gets. The COSC certification only looks at a selected number of movements prior to encasement and certainly in that process the accuracy of the movement can be affected. The QF testing does assess each certified watch in case and mimics the typical use of the watch by a computerized simulation. It is a foundation established by several watch companies (Parmigiani, Chopard and Bovet). At the time of my visit, it was interesting that one of the founding companies had yet to have one of it's watches certified by QF thus testifying to the independence and rigorousness of the testing protocol.
In the end, do I care about the QF certification? Sure within limits. I have a QF certified watch, when originally brought home it had significant problems and had to take several trips back to Switzerland until the movement had to be replaced and the re-certified. Since then the watch has worked fine. Is it within tolerance? Yes. Is it significantly different than other of my watches, not for some. Would the QF certification seal the deal on a watch, not if I there was nothing compelling about the watch. It is just an added benefit but in the end, the watches I collect are not just about time, it's about art and mechanics.
The other thing about the QF certification, it is only meaningful when the watch is brought home. Over time I am not convinced that it does. Certainly when and if the watch goes in for service the certification is probably meaningless unless it is sent back to QF for retesting.
