I was surprised by this inaccuracy too. But was impressed when I learnt that there is no analog wristwatch that can match this accuracy - they are all far far worse. (Isn't it shocking that all those super-expensive Rolexes and whatnot are all going off by minutes per month!) Get one of the Casio watches that syncs to atomic clock radio signals every night - it will be second-accurate all the time.
After observing Seiko 5 SNK809 for 35 days, I can say I´m happy with accuracy.
Overall, it has lost 25 seconds during this time.
It lost most of it when it was sitting on table 2 times during observation. When kept on wrist, it hardly lost any...
