Replacing Battery on a Grand Seiko 9F62 Quartz Watch

[@bensieber6960]

Thanks - beautiful GS movement. Every time I change a battery in a quartz movement I think of the hours of frustration I spent trying to work on mechanical movements. No more for me - quartz all the way!

[@GFWatch]

Hmm...Mechanical movement usually doesn't require a lot of tinkering unless you're a watch maker or when you want to regulate it.

[@trevercarreon]

...yeahhhh, what exactly were you doing?

[@RogerCollectz]

Yes but they’re beautiful in their own ways. It’s just amazing though how a mechanical watch uses no electrical power to work

[@RogerCollectz]

@@trevercarreonhe definitely doesn’t know what he’s doing 😅

[@rbemuscle6058]

Awesome, great to finally see someone taking care when changing their battery. There's no reason to scratch the case in anyway if you are careful. Nice job 👍

[@isbestlizard]

Oh my god it's so clever the watch tells you it needs anothe rbattery! I never would have htought of making it tick twice!!! Seiko are so awesome

[@randallhill7979]

Beautiful watch and awesome review

[@giangvu7902]

That’s a cool looking quartz movement!

Thanks so much for this video! Awesome watch :)

9F movement such a charm!

Good job. Thanks for this video.

Hi has this movement been up graded im looking at sbgx002 with same movement and its about 15 years old..

[@cleftoftherock6797]

Excellent video

[@mark19441944]

Wonderful video! Thank you!

[@MrBacchus18]

When I get a 9f quartz Grand Seiko I'm doing my own battery change so I can see the movement!

[@biharijivandana6894]

Is the movt gold plated?

What do you think about seiko dolce?

Thank you, I will do it myself.

Nice video

[@oufdii7559]

Top qualité job. Merciiiiiiii

[@hermitgreenn]

I was surprised to see that the battery press-fits into its place with no other retention.

[@MarkFenimore]

Same! Most have a retractable prong that holds it down...

[@biharijivandana6894]

Agter seeing your video learned many things and waiting for reply also

[@looseunit1615]

Would it be hard for GS to make a solar movement with a much longer battery life?

[@hmehta0]

Thats the only reason I am wearing Citizen instead of Seiko

[@masalpert]

I know this video is older but if you're still replying to comments I was wondering how you know how tight to screw the case back on when closing it up? Do you just tighten until it stops? Thanks.

[@apnk6870]

In the past I would draw a line with a sharpie connecting the case back and the case. When retightening just make sure the lines connect again.

[@biharijivandana6894]

And that instrument does it removes the dust or it can suck and throw dust again? Like vaccum cleaner

[@GFWatch]

It's just an air blower

[@MyWatchTherapy]

Do you suggest replacing the case back gasket each time you change the battery? What is the gasket reference number? I have not been able to find it. Thank you!

[@GFWatch]

I don't think it's a must to change the gasket every time. It's good but not absolutely needed unless the gasket is in bad shape. Unfortunately I don't have the reference number.

[@MyWatchTherapy]

@@GFWatch thank you for such a quick reply. I am new to this operation so just learning. Do you like the silicone that you are using for the gasket? I might order some hopefully I can get it in United states.

[@GFWatch]

So far so good for the silicone 🌝

[@Sk3tchPad]

Casio: *has a battery inside* Grand Seiko: Installs the battery so that the ‘Seiko’ text is properly oriented when the user has to change the battery. Now THAT is attention to detail.

[@itsallrobbish]

I was thinking that. My potential OCD went off on one when the replacement battery was not similarly aligned!

[@user-gi6kv6rq7p]

I would like to know if you would choose to replace the water resistant ring on the crown of your watch after more than five years of use.

[@GFWatch]

Frankly I'm not too concerned on the crown gasket. It's also a little hard to replace unlike the case back gasket. But yeah, if I have the gasket, I may change it.

[@user-gi6kv6rq7p]

@@GFWatch I think it is worth learning that you change the batteries very carefully. Water in a watch is often caused by water in the crown and I would like to see a video of this in your future work.

[@fabiansosa1526]

Hi, great video, were do you buy the battery please

[@GFWatch]

Bought it online. Should be commonly available.

[@biharijivandana6894]

And gasket is the main reason for water resistant?

[@GFWatch]

The gasket plays an important part in water resistant.

[@Johnsmithxyz213]

Great video,Thank you! I used this video as a battery replacement tutorial. I prefer to replace the o-ring every time when I opened the case. I am wondering what's size of the o-ring of your watch?

[@GFWatch]

The o-ring is in good condition. So I didn't replace it. I didn't measure the size of the o-ring for this watch.

[@Sisun_arumdaum]

Dont need to change everytime

@@user-gi6kv6rq7p I would, but I don't have a 5 years GS yet.

[@andrestenstrup1042]

Did you pressure test the watch after the replacement ?

[@GFWatch]

No but I'm not too worried. I'm not going to go swimming or diving with this watch. I've done several battery replacements on my other quartz pieces and don't have any water ingress issue. If you bring your watch to a watchmaker or jeweler to charge the battery, I think most of them will not be doing pressure test if it's just a battery change. Having that said, I'll always assess the gasket condition. If it's bad, then replace it. Or if you're really concerned, replace the gasket every battery change.

[@dr.stevenpennym.d.3241]

How long does the battery last? Great video thank you.

[@GFWatch]

The battery should last about 3 years

[@johnanth]

Great video thanks. I want to ask how you got the case-back to line up perfectly, with the lion looking up? Was that just lucky or is there a technique to know when you screw on the case?

[@GFWatch]

I guess I'm just lucky 😅

[@bobfrank279]

Note where it is before starting to screw it on. Screw it on and see where it ends up. Note how much off the rotation is. Screw it off. Next, screw it on but rotate it the proper amount, so that it ends up correct.

And i am getting a gs quartz now

[@theram4320]

Do any of you good watch fans know how long a quartz battery will last in a GS? The internet says 3 years however, I've spoken to a couple of watch spotters and a retailer, they've said 7-8 years isn't unusual. Is that right? Or only when the movement is new?

[@anothernailwithjonesy.6713]

I get 5 years easy out of my 1982 seiko quartz diver.

If it is solar powered, I'll have consider owning.

[@c.s.4273]

Use a ball to open if afraid of scratches.

[@GFWatch]

I have a ball. I only use it to open a case back that has been loosened. It can'f open a fully tight case back.

[@c.s.4273]

That is why I prefer quartz movements as there is no escapement working like a hand brake on a car to control the speed while driving and thereby using up most of its energy.

[@michaelh8854]

So the service interval ive heard people say is 50 years which is crazy long! but the question is will these little batteries always be available given the global fight for resources and climate change disasters that will happen over the next 50 years

[@GFWatch]

That's an interesting point. Coin cell batteries have been available for years. Let's hope technology will make it more sustainable within the next 50 years.

[@michaelh8854]

@@GFWatch last point is I wish they made the 37 quartz in a blue in addition to the champagne and black

[@SuperC888]

I want YOU to replace my battery!

[@GFWatch]

😅

[@HeliBenj]

Well the coil is not sealed at all so this is a very risky area, maybe worth mentioning. If you damage the coil the movement is dead

[@shaunharn1998]

Why do you pronounce gasket as ‘Gus Ket’ lol?🤣

[@GFWatch]

Why do you want to make fun of non native English speaker pronunciation? 🤔. Anyway thanks to you teasing, I'll try to improve. Oh, why do you like your own comment? LoL 🤣

[@shaunharn1998]

@@GFWatch I’m a Chinese American so I’m Asian myself and not being racist or trying to insult or make fun of you but I just don’t get why Singaporeans mispronounce so many English words like that. Lol but I gotta say you do a good job at removing the case and battery, my biggest nightmare about quartz is that you might scratch the back case or get dust in, wished every quartz has a separate battery hatch like Swatch it’ll make life much easier and quartz Watch much more appealing, I have like 3-4 Quartz and it’s already giving me a headache worrying about battery leak or damaging the back case and getting dust in when I need to remove the batteries.

[@shaunharn1998]

@ray h. Nobody in the world pronounce GASKET as 'Gus Kert' I'm just correcting him
