How to Change a Suunto Core Watch Battery - DIY

www.breitlingso... - Easy explanation and walkthrough of how to install the battery on a Suunto Core watch. Battery is the CR2032 as marked on the back of the watch case.

[@briankennedy230]

Even my local watchmaker could not remove the back of my son's Suunto Core, despite using every tool at his disposal. I eventually overcame the problem by using a 50 Euro coin (the closest fit ) and gluing it into the slot using a type of superglue (for which I also a tube of glue remover.) This worked perfectly and, after the battery had been changed, I removed all traces of the glue - job done!

[@shannonwomaje4123]

You can keep that from happening again by using a very light...I said very light...I will say that again, because it is a application of miniscule proportion of vaseline applied to your finger tip, then smeared between your thumb so your finger has just a sheen. Then you wipe your finger around the gasket and threads on the cap. Screw the cap back on. The cap was stuck because of 1) contaminants on the threads or gasket 2) Excessive environmental temperatures causing the metal back to fuse to the dry rubber gasket. The vaseline is applied lightly which will not compromise the contacts or battery, but preserves the gasket, and improves the thread water integrity, and future unthreading.

If you don't want to scratch up the back batter cover as badly just get a thin towel or paper towel, fold it a few times, and put it around the end of the screw driver to provide an intermediate surface between the driver and battery cover.

[@Imafreakineatyou]

great vid man! changing these batteries like oil changes

[@USMC-es4yy]

I usually buy solar watches but this is the easiest battery change ever .changed mine there times now

[@borisdraceana]

Cover the slot with cellotape before using a coin to remove the back to avoid scratching. Do not touch the battery at all with fingers, use tweezers. Don't worry you will get lots of practice changing core batteries, the watch eats them.

[@mztriz]

Put tape over the end of your flat head to avoid scratching the watch.

[@JohnThornley]

Has he got a flat head? Seriously, useful tip. thanks.

[@ayase443]

Thanks. Nice video. I made it as you explained. Japanese coin is work to open the case-back though.

[@TheHellaBent]

I've replaced my battery twice with new batteries and every time it ends up reseting itself. what might this problem be and how may i fix it?

[@MrW00LY]

ive been using the one in mine from the factory for over a year now and am just now having to change mine.

[@dk038967]

tnx for showing us how to do it :) awesome watch and easy to read

[@billythekid1729]

So if you dont use compass that often battery life still drains fast?

[@Damon1864]

Use a Nickel locked in a Vise-Grip?

[@Kris-bb4oy]

Hey does it lose its pressurization? Im using x-lander.

[@strongwithraj]

Thank you. Nice video.

[@zkore20]

i changed the battery but after that stay a x in the screen like at the end of you video an don't want to put in hour any help thx

[@GiorgosThessaloniki]

thaks pal, it may seam simply but i want to buy a core and i really wanted tosee how the battery changes

[@nicktrousers]

Hey is there any possibilyty that you can make a review on a marcelloc nettuno 3 2007? Plz

[@dongayanamarasinghe4559]

How long does the battery lasts?

[@usersimple562]

how many days suunto work on 1 battery?

[@heliopijpe]

The screwdriver kills the back cover, had to renew battery 2x,, cause of sticky buttons, causing the backlight to remain on while sleeping, and my back cover looks awful, never did get that backcover coin supposedly included with the watch?

[@manangbinod]

i got my suunto core black watch before 1 year.now it doesn't work.in the watch it shows reinsert battery,does it means battery is finished?i don't understand how long does this battery last for. cr 2032 battery last only for 1 year?i am confused if i need to change the battery or some other problem.please let me know.

[@stunnenbroowie5217]

yes, 1year only of everyday use

[@photoboy2005]

my brand new Suunto came with a dead battery. I have had it for a whooping 10 hours!

[@kalosdios1]

I changed with coin and its very simple just dont push very hard.clean the oring put grease in oring and its ok.

[@ivnkondov_]

Note number 2: Don't touch the battery on the NEGATIVE side with your fingers, use some tools for the job, otherwise your fingerprints may cause problems with the contact...

[@H4nz08]

Where did you get your 2032s from?

[@BrianFolks]

The coin slot is designed for a 1 Euro coin.

[@vasehovno]

@breitlingsource ......OK JUST DID try that again ....nothing , I used bigger screwdriver no luck there, then I made(grind) piece off metal which fit exactly to the back of the watch..and nothing ...damn !!? I guest now I have to go some where ...?

[@vajc0]

thanks, now I can buy them :)

[@vikp6115]

Someone told me if u open battery cover and replace the battery the watch has to be pressurized for the alt. and barometer to work correctly ?? Was he wrong ? That's what kept me from buying this watch.

[@shannonwomaje4123]

I love when people propagate misnomers, rumors and urban legends as facts instead of accessing evidence-based knowledge, or manufacturer's recommendations. Same fools that throw gas on fires to drown out the oxygen. No. A factory preset barometer value (somewhere around an ambient 29.90 millibars or cmHg or even hectopascal scales) is set in the watch, allowing the user to calibrate up or down to a reference barometer. The sensors in watches do not read the interior of the case as this idiot would believe, they have slots allowing the sensor to read OUTSIDE the case. Who was this fool?

[@vikp6115]

that was actually a salesman at the sportsmans wearhouse that told me that about that watch, i guess he was wrong, he told me i have to go to a specefic place that pressurize watches and those places are hand full,

[@vasehovno]

damn ! I do have same watch (all black edition) I did try open with coin...then with screwdriver ,still can't open and I did really use muscles + already scratch back of it ....my are closed really tight ! now hammer will probably help

[@SuperJess1976]

I gots the G-SHOCK riseman... e-friendly Solar power!!!!!!!! If it's poosible to use kinetic energy and solar power... I don't understand why the manufacturers don't charge a liitle more for the watch in the first instance.. and save all this bother and waste..

[@Olywa17]

Has anyone used the kit from suunto with the gasket?

[@1533willo]

Replaced battery screen still black?

[@breitlingsource]

If that's the case there is possibly something wrong with the watch.

[@1533willo]

Breitlingsource wow hope not I have only had little over a year and I rarely use it

[@breitlingsource]

@@1533willo Try shorting the battery?

[@1533willo]

Breitlingsource i don’t know what that means

[@breitlingsource]

@@1533willo search youtube for videos on shorting watch battery. Some watches need it to restart after a battery change. I can't remember if I needed it for the Suunto. If the battery you replaced it with is dead or cheap and not very good that could be the reason also.

[@shannonwomaje4123]

AAAhhhhh!!! Did I just see a $2 screwdriver that doesn't fit the round groove used to remove and replace the battery cover? This means all the torque is transferred to the edges of the screwdriver, leaving permanent pressure nicks in that groove. When I used to sell pre-owned Rolex's, the surest way you can lose money on your watch is for the owner to do something to the $600 case. There are correctly-sized rounds that fit case grooves to open and close threaded plastic and metal battery doors for watches. Just like there are correctly sized screwdrivers for square-cut slot screws and philip screws. Man, lets just use a rock. Let me say it again...AaaHHHHH!!!

[@Packy28]

THANKS

[@aimeevis]

thanks mate

[@wb1228]

A nickel without glue works perfect

[@RRo-up4pg]

2023 here 8 bucks for one battery

[@deplorabledave1048]

As a long time factory trained SCUBA equipment technician and Under WATER photographer, I can tell you that this is the incorrect protocol for maintaining water resistant integrity. CLEAN and scrub your watch first, paying close attention to the case back area. Use warm water, mild detergent solution and a soft or medium bristle tooth brush. At a bare minimum, carefully remove the o-ring without stretching it. Check for nicks and flattening of the 0-ring. CLEAN the o-ring and the case back and watch compartment channels carefully with isopropyl alcohol. Do not touch the battery with bare fingers. Gloves or tweezers, please! LIGHTLY coat/smear the old ring with fresh silicone grease. I use food grade, thick grease suitable for underwater SCUBA gear. DO NOT over grease. A nice light coat will do fine. The best scenario is to actually replace the o-ring each time. That can get pricey since the factory o-ring costs $16 shipped. Lightly grease any new dry o=ring. I have one factory o-ring on the way plus two aftermarket ones for comparison. One more thing. In spite of being MADE in China, the Finland based Suunto company mandates a JAPANESE made 2032 battery for their Core watches. Sony brand, to be precise. I hope this helps.

[@ivnkondov_]

@breitlingsource Well, sorry, i haven't heard that ;)

[@briankennedy230]

Previous post should, of course, read "a 50 cent Euro coin"

[@Gallienus53]

A US 50 cent coin also works nicely.

[@jasonracey9600]

The back on mine will not turn with a screwdriver. Hate Suunto. This is the last one for me.

[@ivnkondov_]

Phahahaha. Note: If you want to scratch your watch, use a screwdriver, if not - use a penny ;)

[@Coleslawbreakfast]

Between the horrible band quality and the battery being a pain to change. This watch just isn't worth the trouble.

[@nomasprime]

DO NOT try this at home! Using screwdriver will damage cover. Take it to a professional, they will have the right tool for the job.

[@Coleslawbreakfast]

Amen!

[@jacko717]

That's incorrect. The Core is designed for the battery to be user replaceable.

[@Coleslawbreakfast]

It may be designed that way but I had to put my watch in a vise and use a very large screwdriver to get it open. I had to put so much pressure on the back of the watch I was scared I was going to crush it. From the factory the back was torqued down pretty good. Just use caution is all.

[@jacko717]

James McVey Ah, perhaps the back case had been cross-threaded? I've changed the battery on my Core 3 times without issue, a little silicone grease on the o-ring is a good idea too.

[@mztriz]

habitullence It says on their website that users should change it else it's a $50 charge from Suunto. Put tape on the end of the screwdriver if you're worried about scratches.
