    Moon Phase Question(s)

    I've recently started to really take an interest in moon phase indicators but something seems off to me. I've been pouring over lists of the most accurate moon phase watches, etc, but I notice that nearly every watch on nearly every list seems to be off about the actual shape of the moon half the time. I'm talking about the "Gibbous" phases of the moon.

    For example on the watch below, the moon is in the Waxing Gibbous phase:

    But as you can see, because of the dial layout, the moon here is still in a crescent shape (albeit a very fat crescent). In actuality it should be in more like a lopsided oval, or rounded (but definitely not crescent) shape, as seen here in the actual Waxing Gibbous moon:

    I guess what I'm learning when people talk about 'accuracy' they are talking about the actual time it takes for the moon to go through its full cycle from full back to full again...? Is no one concerned with properly representing the actual shape of the visible moon during its cycle?

    There are some that manage to pull it off by using an actual 3D ball instead of a 2D disc, like this De Bethune, shown in its proper Waxing Gibbous phase:

    Is it just too hard to do? Or does no one actually care?

    Or...this is entirely possible...am I missing something?

    Re: Moon Phase Question(s)

    I haven't really thought about it..and now that I did, I don't really care

    Seriously though, I thought they only put the moon phase complication for aesthetic reasons..there must have been some legit reasons before but I can't think of any right now..

    in my own opinion they are mostly meant to be aesthetic and look very 'purrty'. however, there are some time pieces with very accurate moon phase readings.

    Moon phase is the most useless complication. I don't mind having it on my watch but it can't take half the dial estate like the above watches.

    I have found it much cheaper just to look up.

    Re: Moon Phase Question(s)

    I have a winder specifically so that I don't ever have to set my moonphase again... anywho, in the few times I bother to check the moonphase, I am essentially looking for two pieces of information:

    1) is the moon waning or waxing?
    2) how soon will the next new/full moon be?

    The degree to which the moon is waning/waxing and how the watch accounts for that, isn't really noticeable/important for me

    Re: Moon Phase Question(s)

    These days, the purpose of a moon phase is to delight its owner with simulations of the phases de lune. That is all. I love my moon phase, but I'm not crazy to think that accurate depiction of crescents and all matter.

    Re: Moon Phase Question(s)

    I've actually thought about this a bit and have wondered the same. But I think a truly accurate depiction of the phases would be pretty difficult for a traditional moonphase complication, because the "shape" of the moon changes from just a sliver of a crescent, becoming thicker to a perfect half circle - then to the lopsided oval shape of the gibbous, and becoming more circular and less oval shaped as it gets closer to full. It's similar to the longitudinal lines when looking at a globe - they "straighten" as it gets closer to a half-full moon, and become more curved as it's nearing full or new moon.

    So they would somehow need to obscure not only the correct part of the moon indicator, but also the correct shape (and side) to truly depict the phase accurately. This would also create complications (no pun intended!) if selling internationally, since the moon appears upside-down in your non-native hemisphere.

    This close enough. Set it once every 20 years or so when the Eco-drive goes.
