    Leaving crown unscrewed

    Just got my 5000 Caribbean today, but I'm still into wearing my Sinn U1 and O7 LM-3. Is there any harm in leaving the crown unscrewed so that I can wind it every so often to keep it going?

    I'd like to have it run for a while to make sure there are no problems. Doxa's return policy is 10 days.

    I did do a search on the forum but the answers were not clear.

    Personally, I would not. More than likely, your location has a bit of humidity in the air. Some are more than others. The humidity level where I am located is usually >60%. Leaving the crown unscrewed can subject your new watch to undue moisture.

    There is no harm in screwing/unscrewing your crown.........as Long as you are careful

    Precisely what Jason said. I would never leave a crown unscrewed. Keep it sealed up, the way it was intended to be. If you don't want to wear it for an hour or so, just wind it again in a day or day and a half. Keep in mind, timekeeping may run different at rest than on your wrist though. Especially if left in the same position the entire time.

    ^^ I have found that my watches seem to be a little more accurate on my wrist than on the winder.

    Re: Leaving crown unscrewed

    This question may be better answered on the watchmakers forum. IMHO, I don't think leaving the crown unscrewed will allow dust and moisture into the movement. I have a friend here that is starting up his own dress watch company and he said he can leave the crown out on his in-house movement prototypes and they are still water resistant to over 100 meters...and that's on a dress watch! I think sometimes we baby our Babies too much.

    Good point. I totally agree here. I think the crowns of modern watches are leakproof enough to keep away dust/moisture that is in the normal air and not under pressure. I don't know how the Doxa-crown is constructed or how many seals are used. Found this pic in another forum showing the perfect Rolex-Triplock-crown mechanism:

    Re: Leaving crown unscrewed

    I think the crown could be easier to break off if the stem is left unscrewed. No way you could harm a crown screwed tight to the case.

    In any case, how can moisture get passed that Trip-lock
