Yeah, but I'm sure your microwave isn't mechanical. What makes a mechanical watch cool, even a cheap one, is that there are no electronics at all - just gears and springs and things. I think that's worth a trivial bit of inaccuracy even if a boring $10 digital watch can easily beat a $200 mechanical one in accuracy.

My guy a mechanical watch should lose like a minute a _month_, tops. Get your watch serviced.

A real, completely mechanical watch? No battery or crystal? I'm sure my Seiko isn't be best there is and maybe it could be improved with servicing, but I think electronics have given people unreasonable expectations of accuracy

No, the people responding to you are correct: even the crummiest mechanical watches should not drift by more than 10-15 seconds/day. COSC certification, which most nice mechanical watches have, requires no more than 2 minutes/month (4 seconds/day) of drift, and most do even better than that, 1-2 seconds/day is normal.

If your Seiko is really drifting by minutes per day, something's badly wrong with it and you should get it serviced.

I collect watches and even my cheapest old Chinese automatics will lose like 30 seconds per month or so.
