Seiko claims that the accuracy of caliber 4R36 is between +45 / -35 seconds per day.
Such inaccuracy is just crazy for an automatic watch. You have to set it to the right time every day;-(
The Swiss movements are 1,000, and they still have a bright future ahead of them. My automatic Swiss watch is accurate to +/- 3 seconds per day. Setting it back to the right time once a month is enough.

Swiss movements are 1,000 times more precise.
