"a few seconds a day" why is that accuracy even needed? Sure, if you work with computers (that can tell time too), or are a mariner without GPS. But otherwise, just live with it.

Over a week or two that will accumulate enough error to make me miss a tram. Of course, you could just re-set the time every week, but there's your downside.

It's a watch. It's an item that literally has one single job: tell the time accurately. It goes without saying that it should do a pretty good job at this and be accurate.

Of course, that inaccuracy isn't a problem for most uses.

But for me, having an accurate watch reduces cognitive overhead and mental noise: I never worry whether the watch is wrong, and I never wonder about the last time I set the watch. Combine good accurary with a 10 year battery or solar and we're in full zen mode.
