How many seconds of time accuracy have you found that this watch loses over the course of its 7-year-long battery life? I think I can handle it losing 30 seconds of accuracy per year.

I read Casio promises 30 sec/month but (lucky?) customers report losing 2 seconds per month. I know its a cheap watch but would it be that hard to have a settings for it? I hear people tuned antique pendulum clocks to seconds per year. I suppose it helps that they are inaccurate enough to have tuning?

It's more like 30 per month. It really depends a lot how much you wear it outside because it's not temperature compensated. I don't really mind a lot because I will just adjust it once in a while. But I wouldn't claim it to be an accurate movement.

  Oh, it's adjustable!? In that case, who cares?

    Of course you can just set the time again when it's wrong. It doesn't have an adjustable offset no. But it doesn't work like that because it's temperature dependent anyway. So the offset is not stable.
