    My Mark XVI uses a Calibre 30110 which I've been syncing daily to the atomic clock.

    I've noticed over the course of 24 hours its losing around 12 seconds. Is this bad or to be expected? Its not the end of the world but just wondering if these movements run slow? I know they're originally made by ETA and then jazzed up by IWC.

    Last had it serviced about 3-4 years ago.

    Hi Tom,

    This kind of thing can happen a couple of years after a servicing. I'd advise you to go to a certified IWC watchmaker and it's probably just a quick daily rate setting unless he says otherwise.

    PS : it can also happen if the watch took a hit of some kind.
