If you can return it and order another. While within specs for Seiko to send it out the door it would bother me to no end.

The 2 minutes overnight thing is definitely not normal but as for the rest, you're well within spec for that movement which is -35 to +45 seconds per day.

Re: the previous post, you'd return a Seiko 5 for running +/- 15 seconds a day? I don't know what people expect from cheap automatic watches; it could be a lot worse than 15 or 20 seconds out.

 

One of the reasons I buy from sellers who accept returns. I realize that the watch is inexpensive relatively speaking, but $300 is something to me and if I was not happy and I have the ability to return I will. My rule is around +/-7 to10seconds a day, and believe it or not most of my affordable autos from Seiko are either within or close to my expectations.

The 2 minute overnight was a horror. But that was the day received and i was CONSTANTLY shaking and moving it about. I agree regarding going through a return or exchange. I could very well end up with the same problem or worse. And from what I've been reading on this, it should be worn for a while to settle itself in.

RE: Aguila9's post: It does drive me crazy. But this is most certainly not a $300. watch. If it were, it'd be back in the mail by now along with a stop payment on my credit card.

 

That's understandable then, despite shaking it and stuff you probably actually hadn't wound it up much and the power reserve was running down. I'm pretty sure mine gained a load of time once when it was running out of power reserve. Personally, I don't believe in the burn-in thing and haven't experienced myself; mine runs exactly the same now as the day I bought it new. I think some people like the burn-in idea as they aren't happy with the initial time keeping and it gives them some hope that their watch will start performing better.

 

Hmmm 2 min is a lot but what did you use to time the watch? Did you back hack it? I find that when you engage the hands using the crown advancing the hands forward you feel the tension but if you move it back it can move without resistance so there can be a discrepancy between what the minute hand is pointing to and where the actual minute pinion gear is. Unless of course you used a timegrapher...but then you still have to take positional variance into account.

If it's 2 minutes evey night all week then I'd be concerned otherwise it sounds like you're on spec.

 

It's a bit of a split decision. If I was in your shoes I'd either send it back now in the hope of getting one that's better behaved or live with it for a while until it beds in then get it regulated if things don't improve.

 

It sounds like it was magnetized or the hair spring is overlapping and caught on itself.

If you have a simple compass, let it settle on north then pass the watch over it at several angles to see if the needle moves. If so, get a $10 plug-in, push-button demagnetizer.

If it’s the hairspring, sometimes one can fix it by placing the watch dial down on your palm and giving it a few firm pats on the case back.

 

Did you check the time right before you went to bed, then check again in the morning? If you did a lot of "winding" between checking the time, it's possible the swinging around caused it to gain some time. I would wind it up as full as you can before bed, set it down, then check the time again when you wake up.

This was an interesting video that someone else posted here on the forums:

 

At this point, its behaving pretty consistently. The 2 minute gain overnight happened only once and never again. I'm still at about +15.
I do have a 30 day return/exchange. But it came from one of those large distributors, where you sacrifice the Seiko warranty and you are under their warranty.
You have to pay postage (certified and insured) to and from. If they decide it's not defective, you get it sent back, etc. I'm guessing we all know of the place I'm talking about.
Anyway, this Seiko 5 was 69 USD. Postage, the way they "demand" it be sent would be at about 20USD going and 20USD coming. And i'm sure they will determine the +15 is well within specs and not defective.
If it continues to bother me, I'm better off getting it regulated locally.
Thanks to all that replied.

Yes, +15 is completely normal, also for watches that cost 10 times that amount.

If you take it to a watchmaker there is a good chance he'll just go "wot? you mean 15 minutes fast right.. Oh 15 SECONDS?! Why are you and your 69 dollar watch here? May I interest you in this here Casio?"

You could also regulate it yourself and get it a bit better, even without any equipment other than a caseback opener and a plastic toothpick. It'll be a couple days of trial and error though.

Well, $69 or not, the majority of the 5 series are $50 to $75. watches.
Anyway, since I couldn't get the keys out of that bracelet, I took it to the Jeweler for sizing. I talked about the + at 15 to 25 sec. per 24 cycle. He said (jokingly) he'd be glad to take my money, but he's dealt with Patek Philippes' and IWC's with a much more noticeable + / - situation. And that he only made those repairs because the customer insisted and paid an initial fortune. His advice was to simply wear it and keep an eye on it. If it goes into minutes per day, then $15. to regulate. I think I'm okay. But it's still annoying as hell!
RE: HANTMS: Sure, I'd love to look at the Casio Thanks to everyone for their input.

 

Can anyone tell me the advantage of a Japanese made Seiko 5 (with the same 7S26) as opposed to a Singapore export Seiko? (other than increased price)?

 

My japanese made Seiko 5 with the 7s movement ran fast for a while. I was always gaining about 30 seconds a day. At the end of the week, it was very noticeable.

But recently, it's definitely gotten better. Wearing it every single day for months now and leaving it on the night stand with the crown facing up (not sure if that really makes a difference) and it's much more accurate than when I first got it.
