Query: Looks nice but total DUD for accurate time

I bought this watch on Amazon. The selling points for me were the classic styling, the low-key looks, and the self-winding movement. Well, I hate to say it, but this watch has been a complete dud. It is horrible at keeping accurate time. For example, it requires a daily reset of the time. I set it this morning in sync with my iMac (which gets it's sync with the Apple time server, so I know thats accurate). This was at 10:43 AM. Now, with my computer showing 11:26, the Seiko watch shows 11:30. Now, I understand that a mechanical watch will not be as accurate as a quartz watch, but a gain of 4 minutes in less than an hour is ridiculous. It essentially makes the watch useless. It seems counter-intuitive that a watch would GAIN time after being wound, but if I wear the watch for a full day, by the end of the day it can be almost an hour AHEAD of the true time.Waste of money.
