15s per day sounds EXTREME. Are you even serious? Even the cheapest Chinese hand watch has 50x better precision.

Cheap watches are almost always quartz watches (electronic). Those are much more accurate than even high end mechanical watches.

15s per day is not unusual for a good mechanical watch.

I am serious, mechanical watches are fascinating but they are much less accurate that a cheap quartz watch.
