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.

Watches are jewelry. Telling time isn't even their main purpose, nevermind telling it accurately. Of course, maintaining accuracy is part of what makes them cool to the people who like them, but even if they lost several minutes a day, I suspect my watch wearing brethren would continue to wear them.

Define "accuracy".

What, if anything, in your life needs to be done with-in ±5 minutes? If the analog minute hand "should" be on 2, but it's closer to 1 or 3, how many things will fall apart in your life?
