For a Seiko 5, not unreasonable accuracy. Might be possible to regulate a bit.

Is this normal? I know it's not my old Rolex, but I was hoping for better accuracy.

Yep; that's pretty normal. Once the break-in period is over the rate would settle down to a more-constant level. If it's losing 8 seconds per day, you could definitely adjust it to something closer to zero, although it's unlikely you'll get it perfect since ambient temperature changes will affect the rate on a Seiko 5 more than on higher-end watches. If you don't have a case wrench with which to take off the back, you might be able to get a friendly watchmaker to open it for you, and you can then do the adjusting yourself over the course of a few days, nudging the adjuster on the balance cock just a TINY bit each time until you get an acceptable rate. Or a watchmaker's fee for doing the adjustment may be within your budget. It just depends.

Well, I guess I better find a watchmaker, then, since I don't see an adjuster or a balance cock through the clear case back. Of course, I have no idea what they would look like...

Seriously, though, I'm glad you both suggest it can be adjusted. A little fast is fine, I'd even be happy if it was gaining eight seconds a day, but not losing it.

Should I try and find a Seiko dealer so I don't screw up the warranty? It's good for another 2-1/2 years.

Other than the accuracy issue, it's a fine watch for my purposes, and I'm glad I read about it on this thread, and bought it.

I've been pretty happy with my Seiko Dolce (HAQ quartz), keeping within +/- 1 second/month. Also my Marathon WW194015SS (not HAQ), keeping +/- 2 seconds/month. The Marathon is for sale in the Classifieds, as I have come to love the Seiko.

You may need to tilt the watch so the rotor moves out of the way in order to see the balance.

The way moving the balance adjustment changes the rate is by making the active length of the balance spring shorter (faster) or longer (slower). Here's a short video on YouTube about it: https://www.youtube.com/watch?v=Ui_QnDKciBU

Thanks, Brian, it does look simple to do. Unfortunately, I don't have a case wrench, so I'll try and find somebody to do it for me.

If I may, you might look into an app for timing your watch (I use Watch Tracker) and test your Seiko's positional variance. There's a decent chance you can find a resting position that either the slows the loss or actually goes positive. If so you can regularly place it in that position when it's off your wrist (e.g. when sleeping) to balance it out.

Positional variance (for example, -10 dial down but +6 dial up, -3 9 up and -12 6 up) is the biggest +/- with any mechanical watch, and more so with less expensive movements. I'd try that first before breaking it open, because if your difference between positions is huge you are only addressing part of the problem.

I always leave it on the nightstand overnight, face-up, so I'll try it face-down for a couple days and get back. Thanks for the suggestion, which reminds me of a Rolex ad from the early 1960's making the same observation.

That's a very good point. At the shop we used various methods for correcting for positional variations. First, of course, was making sure the watch was as free as possible from excess tolerances: end-shake in the gears, out-of-poise balance wheels, non-concentric hairsprings, etc.

Then we'd check the timing in various positions. The timing machine I had on my bench had an automated pickup that would move to the different testing positions as needed, like this:

Then overnight I'd put all the day's watches on the Cyclomotion for the night:

It worked pretty well, but every now and then I'd get a customer coming back who always sat with his wrist in one position on his desk all day, or at the controls of her jet for eight hours, or whatever, and wasn't getting accurate rates; so I'd have them track their rate for several days, and then I'd make an ad hoc adjustment for their particular variation. It was fun. Uh huh. Sure.

I can contribute!
Seamaster Professional Chronograph.
I always eyed the Planet Ocean and Speedmaster "moon watch"

I understand the chrono of this watch is not as popular but I quite like it.
It was a present (a very generous one!) so no way in hell would I trade it for anything.

Besides, it's nice having a date feature and it feels like it can handle the world ending.

Forgive the smudges on it, my girlfriend's dog already tried to eat it off my wrist.

I really like that one; congratulations. The date is very understated and fits the "feel" of the dial very well.

I like the red hands against the blue background.

I've got a couple of chronographs with difficult to read dials due to low contrast. Not the case with that one.

I'm not a watch guy, but this Rolex my biz partner just got makes me all warm and fuzzy.

A new, gold Sky Dweller will sell for a little over US$30,000.

He drove a new Bentley betayaga in today. That doesn't really shock me. I couldn't imagine ever spending that on a watch (or anything other than a house or car)

Forged carbon is not the best material for a "beater". It definitely dents and dings. AP's only all forged carbon watch is still the Alinghi Team Chronograph. I owned one for a year and never had a problem, but if you are prone to hitting things, the material is not durable.

That thing is so ugly, even if I was a billionaire I'd save the money and get the fastest Cayenne on the market. I've seen 5-10 of them on the road so far, from every angle, and man it's an ugly thing.
