    Fortis Classic Cosmonautis Chronograph Ceramic PM on Bracelet

    I recently purchased this watch. When I received it in the mail, the chronograph hand was off by about half a second. Is there any way to recalibrate the second hand back to zero? I've seen a few videos on the internet on how to do this for other watches, but can't find how to do it for this specific watch. Any help would be greatly appreciated.

    Doesn’t this little chappie have the 7750 movement in it? If so I know of no way that the owner can recalibrate a mechanical chrono. A quartz one, yes but not a mechanical one.

    Is there anything I can do about this? I paid a pretty penny for this watch and would like it to be calibrated correctly

    I may be wrong (it wouldn’t be the first time) but I’m pretty sure this is a job for a watchmaker to put right. If you purchased it from a dealer then think about making use of the warranty.

    I just looked at it again. It's between a quarter and a half a second off. Would this be considered an issue to the manufacturer, or no would this be considered "within tolerances"?

    ^^^^^ This is how you should deal with the issue. It's a simple fix for a watchmaker but if it's new, take it back to the AD. Nice watch by the way.

    It’s not an inexpensive watch so if you’re not happy with it then it’s not within tolerances. As a guideline all my chronos are spot on.

    Why aren’t you asking your AD if it bothers you? They’d be able to help address the issue. Should be the first place to go.
    I don’t think that there is a way to address this without opening it up.

    Contact the person/ retailer you bought it from.

    Yup take it back and get it fixed. Fyi I have had a 7750 in which the chrono occasionally slipped a second ahead or behind. It happens when you reset it and the hand whips back so fast it slips a notch on the gear.
