After owning the first one and it gaining 30 seconds a day and sending that one back, the second one which amazon shipped out kept great time gaining less than one second a day. However, the biggest downfall of this watch that isn't mentioned much is its power reserve. It wouldn't even stay wound enough to power it from early evening to the next morning. There is no manual wind mechanism on this, it's all from your wrist movement. Also, the watch band is very small and if you have even small wrists, it will look like a woman's watchband. I put a nato band on it and that fixed it but it is a small case watch. I would recommend the citizen eco-drive 8180. It is a bit larger and it never needs a battery. Also, with its made in japan quartz mov't, it will be the most accurate watch you'll ever own. The Seiko 5 is made in Malaysia, and evidently you are getting what you pay for, online cult following or not. One last thing to mention re: the Seiko, the mov't is the new C mov't, not the B. This is a big deal. Back to amazon this one goes too.
