    Default Newbie Question: How to determine watch size

    I'm new to collecting pocket watches and I have a couple of watches that I would like to know the size of.

    My question has to do with where the measurement is made. Is it measured on the movement, on the case or somewhere else? I have a set of calipers and an old chart that has the sizes and corresponding diameters, I'm just not sure where to measure things.

    Thanks,

    Ed,

    American pocket watch movements are measured across the dial side plate (pillar plate). Normally, the dial is the same diameter or very close, but occasionally the dial will be significantly over- or under-sized.

    Wayne,

    Because Ed asked specifically about pocketwatches, I skipped all the not-circular wrist watch size complications.

    From curiosity, can you think of an American pocket watch movement in which the pillar plate is not the widest plate? There probably are some, but I can't think of one off the top of my head. Maybe some dollar watches?

    Wayne,

    Well, I looked throught my Elgin graveyard, and didn't find any that had a "smaller lip toward the dial", although many have a dial that is smaller than the pillar plate. If you run into a specific example please post it, I still can't think of any.......
