    Question Glashuette chronometers?

    Does anyone know if Glashuette (observatory?) has started certifying watches as chronometers? I remember seeing a couple of limited edition Zeppelin models certified by Glashuette. Is this going to become a regular feature and a genuine option for watch companies to get their timepieces certified? Will this practice (if widely adopted) provide some competition to the COSC certification process?

    I look forward to some informative replies, thank you ...

    I think it IS another COSC facility, and they are doing certifications. GO's Senator Chronometre was rated there I think.

    i believe the difference is that any country can send a watch to be certified in glashuette. it does not have to come from glashuette. where COSC watches have to come from Swissland.

    Yep, have a look at the Wempe watches. A lot of them are certified at Glashütte. Mühle does use the observatory too.
    Kind regards

    As Ulacf. suggested, is it owned by COSC?
    Are the testing methods and criteria the same as COSC?
    I know I could search the Net, but I am lazy today!

    No. Owned by Wempe.

    No, based on DIN 8319 which specifies a fifteen-day series of tests.
    The accuracy of the candidate’s rate is tested in five positions (crown left, crown up, crown down, dial up and dial down). In each of these five positions, its average daily rate must not deviate by more than -4 or +6 seconds; its average daily rate deviation must not exceed 2 seconds; and its greatest rate deviation must not exceed 5 seconds. All watches are tested at 23° C, 8° C and 38° C at 50 percent humidity. The results are measured every 24 hours, after which time the movements are once again fully wound. On the tenth day of the test, any possible complications are activated in order to measure the effects of these complications on the accuracy of the rate. Two special features of the German norm stipulate that each watch must be set to the second and that each candidate must be tested inside its own case in order to preempt the possibility of potential deviations.
    All that remains to be said is that all WEMPE CHRONOMETERWERKE GLASHÜTTE /SA and WEMPE ZEITMEISTER GLASHÜTTE /SA wristwatches have passed the meticulous tests administered by LMET and SLME. This means that each timepiece has earned the right to display the predicate “officially certified chronometer” on its dial.
    Text borrowed from Wempe.

    Re: Glashuette chronometers?

    Excellent information, thanks again Mike!

    So, it seems that one major difference is that the uncased movement is tested by the COSC whereas the cased one is tested by the observatory. Do you think the testing fees are comparable, and whether more watch companies have decided to get it done through the observatory rather than the COSC?

    Mike, you maybe understand why I/we missed you!
    A well of information.....

    So, the testing is a couple of notches above COSC. Just like JLC's 1000 hr test.
