Jag har en IWC Portuguese 7 day reserve.
Som ni alla vet så chronometer testar inte IWC sina ur. (Det är iofs rätt få av de ”finare” märkena som gör det)
Iom detta så har jag gjort en test på min IWC.
Enligt deras hemsida så accepterar de 0s i negativ avvikelse men upp till 6s fortning per dygn.
Min fortar sig ganska exakt 5 s per dygn oavsett om jag använder den eller om den ligger i sin låda.
Jag vet också att klockor med stor gångreserv ofta avviker lite mer. Min fråga är egentligen ifall 5 sekunder är acceptabelt? Själv bryr jag mig inte men det vore kul att höra andras åsikter.
Vad har ni för avvikelser?
(För att få chronometer stämpeln krävs maximal avvikelse om -4 till +6 sekunder)

There's nothing wrong with COSC certification, but frankly it is used primarily as a marketing technique by a few mid-priced watch brands to legitimatize themselves with unsophisticated buyers.
Most of the "higher-end" watch brands, which sell for much more than Breitling and Rolex, seldom and sometimes never COSC certify. These brands include:
Patek Philippe (except two or possibly three models in the past 20 years)
Vacheron Constantin
Audemars Piguet (I think they have one lower-priced --for them- model they now certify)
Breguet
Blancpain (possibly one model as an exception about 5 years ago)
Jaeger LeCoultre
All of these brands, and many more, are considered superior, or at least at higher average price points, than the two you mention. There are virtually no $100,000 watches COSC certified. Rather, COSC is used by a few companies --the two you mentioned especially-- to legitimatize themselves to newbies in the 2000-6000 USD market.
COSC is OK --the watches are tested and there's nothing wrong with the results (event though the movements are tested uncased and all watches change "accuracy'" over time). IWC has more stringent standards (see "faq") but the real issue is totally different. And actually whether a watch is +3 or +7 seconds a day fast really has zero to do with quality, artisanship or even practicality of use,
