    Unscrewing crown in humid environment?

    When l need to wind or set a watch, l try to do it at home because the air conditioning keeps the relative humidity in the apartment at 50-55%. ls it ok to unscrew the crown in a humid environment? Am l being overcautious?

    Are you also setting the watch in the dark? You wouldn't want any light to get trapped in the case, especially if it has lume on the dial. The trapped light will deteriorate the lume at a faster rate.

    Overcautious might be a bit of an understatement. It would be the equivalent to wearing full scuba gear to walk out in the rain so you don't drown.

    Ya'll probably aint from the South where Ya'll can drink the air. I've lost cameras and other electronics because they "fog up". I can see where OP is going with this. I don't think it would be an issue, but if you have been down South in the summer, you know why he would ask.

    I dont think it's a dumb question. I mean plenty of vintage watches including divers show degradation and or oxidation of the dial some of which does make me question whether humidity played a role. So from a long time preservation perspective I think it is actually a decent idea (as is ensuring seals are kept up, and that work is also done in a well controlled environment)

    Yes, it’s OK to unscrew a watch’s crown in a humid location. I do it almost everyday and haven’t seen anything negative happen.

    But those watches also have vintage seals (= often crumbled to dust). For a modern watch that's not too old it's not an issue.

    Most watches with screw down crowns always have a seal that is preventing entry of moisture, even when the crown is unscrewed. I say most, but in all honestly I've never seen a watch that didn't have this, but as soon as I say all someone will post an example of one...

    So as long as the seals are on good shape, I would not be concerned. But remember that water resistance of a watch is not a permanent feature, and it must be maintained. If you regularly get the watch wet, it should be pressure tested on a regular basis also, and have the seals replaced as well.

    Cheers, Al

    I concur.
