Seiko 62mas losing time

Likely unlucky, Seiko QC is not the greatest.

I doubt it’s anything you did, but in the future I might take it off to chop wood.

These prospex watches are not so shock resistant so yeah, don't expose it to such shocks like feom chopping wood or similar activities

You are probably unlucky. My SPB147 is behaving erratically and I'm not chopping any wood with it. My SARB017 which has a previous gen 6R15 is better but nothing to write home about, and the islander ISL-68 with its NH36 is surprisingly the best.

Seiko movements are often qualified as "workhorse movements". They are supposed to be almost bulletproof from a longevity POV. My own impression is somewhat different because I think they are mass produced tired plodding movements that are kept alive with minor improvements from one generation to another. They are also not regulated so I somewhat doubt that if they replace the movement they will also go the extra mile and regulate it before shipping it back to you.

You're basically testing the limits of the built-in shock resistance. Every single time.

While you might be okay in the short term, or sometimes even the long term, the laws of physics do still apply to all of those delicate gears, balance spring, hands, etc.

Don't chop wood with any mechanical watch on your wrist. Watches are shock resistant but usually advised not wear when exposing to heavy shocks and sports. Any activity which causes a sudden, violent and accelerated motion to a mechanical watch should be considered carefully. Or you should be on the market for Richard Mille 😜

I would have asked them to regulate the movement for now and return the watch to see how it behaves for a while before sending it for a complete checkup. But also it is a good thing to get a fresh movement incase if the impact has caused any issues within the movement.

I've just sent my Willard (spb151) back to Seiko UK service centre for a bezel repair and asked if they could regulate it , but they replied that they don't offer that service 🤯

I've had mine for over two years, it was really accurate at first, but recently I've started to have the same problem.

Not your fault mate, those 6r movements aren’t the greatest Seiko movements….

Thank you all for your comments. I think the conclusion of this is I need to buy another watch for more shock activities… g-shock it is.

I took a very similar pic yesterday!! Killer watch man!!! Mine runs a little bit fast (about 12 secs per day) but I can live with it. I have read that it is not uncommon 😔. On the other hand, I own a few turtles and they run crazy accurate… I believe it comes to “luck” at the end…

Could also be magnetised?

Yep, buying a Seiko is essentially buying a ticket for the accuracy lottery.

We know Seiko movements can be accurate, micobrands regulate them all the time, but Seiko won’t, even on their higher end pieces.

I love Seiko, but this shouldn’t happen.

I thought magnetism (usually🙄 ) makes a watch run faster? Anyone correct me if I'm wrong.

P. S. If I were to chop wood, I'd use an axe, using a watch is just asking for trouble. 👀🙄🤔😂😂

Beutiful dial, yes I think it is just luck of the draw. The showroom told me that they will regulate the watch when they get it back from the factory.

I don’t work with magnets, at least I don’t think so.

I only usually wear mine a day or two so I don’t care . I wouldn’t wear it out on a long trek where accuracy was crucial, I would take a digital watch with a new battery:)

Spot on. The 62MAS is an awesome watch. But it's not a wood chopping watch. And if you don't believe me, go and talk to a watchmaker. Ask them if you should be chopping wood, wearing an automatic watch. If they stop laughing long enough, they'll tell you, "no". It's quite bizarre to see some people in this thread suggesting that wood chopping is fine and it's just the Seiko movement that's the issue. Such people clearly know little about watches. And again, if you don't believe me, ask a watchmaker. Ask someone who takes these things apart on a daily basis and knows far more about them than rando's on a forum.

I’ve had mine for a couple of days (purchased used on EBay) and it’s slow too. Never had a watch run slow. Likely going to the ask local watchmaker to regulate it.

This is the reason, I owned the SPB143 twice, and sold it both times. For the price point it needs to have better movement than this. Good luck hopefully they will sort yours out.

Yea I can understand where your coming from. This watch is more of symbol for a point in my life so I will keep it forever.

I would send it off to Seiko for service as it's under warranty. They will regulate the movement

Although it’s possible, I doubt the watch was over a minute off when it left the factory. But I bet it left the factory with a defect or misalignment. More than likely whatever is causing it to be off is being exacerbated by the repetitive banging and shaking from wood chopping; essentially made it more apparent.

Same sentiment here. I have a 7S26 SNKL43 and a 4R34-equipped SSK GMT. The GMT runs at -2 seconds per day while the SNKL runs at +15 or so. All luck of the draw really (mind you I suspect the GMTs get regulated somewhat from the factory as they seem to be more consistent than other 4R-equipped watches).

I suggest something like a G-Shock when shopping wood. Automatic movements can be damaged

Ofc it can. Modern watches can take a lot more than one might expect. The guy that makes Islander watches had an episode on his YouTube channel where he gave one of his watches to a guy that does mountain motorcycling, and that bloke wore it for months without any issues. Here is just the movement Seiko cheapens out, that is all.

I don't think you should be chopping wood with a mechanical watch, certainly not an automatic with a heavy rotor, on your wrist. Not just Seiko, the same will happen to a Rolex. It will probably keep time a bit better for a bit longer but subjecting delicate moving parts to shocks is not ideal. It certainly can whack a few things out of balance and mess up the rate but even if it doesn't, at the very least the bearings of the rotor will wear considerably faster. In fact, I think Richard Mille adjust the automatic winding systems specifically for people who whack their watches about like crazy... so if you get them to design you a movement (like Rafael Nadal or Bubba Watson) it might be alright. Can a "normal" watch take it... they went to war didn't they? Well, yeah, for a while it should be fine but you'll have to service it more often. You were probably unlucky with this one but to some extent this is expected behaviour. And that costs money once out of warranty, not RM money but still 😉

I have a Seiko with the same movement. I baby the watch but it kept terrible time. I took it to get it regulated, but the time graph was a mess. Very fast in some positions, slow in others. The guy serviced it and it now keeps reasonable time, at least in line with Seiko’s entry level movements. He said there was something wrong with the hairspring or something and I should take it to a proper Seiko service center.

Given that Seiko doesn’t make any great claims to accuracy to begin with, I’m kind of done with them. I love the brand, but to me, they’re a fashion brands. They build loyalty with their inexpensive Seiko 5 line and offer up-market models for their customers to buy as their income goes up.

Yeah, you shouldn’t be chopping wood, swinging a golf club, or any other quick acceleration and stopping with it. There is a limit to what “shock resistant” means.

I wouldn't chop wood or do any drumming, even if it doesn't damage anything in the short term it messes with accuracy. Good looking dial on that one though, and I like the boots.. Wolverine 1000 miles by any chance?

Loake chukka boots, and thanks I love the dial on this Seiko
