This video is on how
to replace a
watch battery I've got 2 types
here. One's a snap back and the other
is the screw type back
and we'll go over how to the replace the battery on both those
the first step is to make sure the back to watch is clean
and anything that falls into the watch can damage it so you wanna make sure your
hair's not wet you're not sweating
make sure your hands are clean. Wash your hands, get all the oil off
your hands Use soap and water and make sure that
back of the watch is a clean I would not recommend using water back here because
again you do not want to get water in the watch
so a nice dry cloth and clean it
well. A brush works well, I have his
little brush a cosmetic brush that's never been used for cosmetics
but it's a nice, stiff dry brush it will brush stuff out of the way
okay so the the next thing is to
look for a notch in this case there's a notch
I don't know if you can see it on camera, but there's a notch
designed for popping the back off and that's where I'm going to push the tool in to
and then I'm going to use a prying motion both this way
and back and forth
my "common" tool is this old steak knife
and I've put some tape on the edge so I don't hurt or cut my fingers
by accident
the tip is still sharp
and these are brittle. You can pop a piece off and it can go in your eye
so be sure to wear eye protection I'm also going to
hold the watch with a towel so that I don't cut myself and what you do is
you set the
knife into that notch and you push in and you twist
and it pops off. We don't want any dirt falling in to the watch and that is very
common to have a lot of grunge
around the outside, so make sure that there is none there
you want to use a clean lint-free cloth
to wipe around the back and also notice on the back there's a notch
and when we go to put the back back on the watch, it is very important to line it up with
the
with the setting stem
in this watch here the battery it is round thing right here
and to get the battery out
you can see here there's a finger here little finger here maybe
you can see. And then there's another finger over here
like a spring tensioner so I'm going to take this plastic thing out to get it out of the
way
Notice that this plastic thing also has a notch in it
and that's got to line up with the settings stem
to get this battery out
you push it away but I also have to pry it up out of there because the battery is
sitting in
a little hole. I am going to lift the battery up against the spring and then
push it out with my thumb
and we'll see how that works
worked first time, excellent. Here's the battery
notice that the plus sign is up. You probably can't see it, but there's a
very tiny little plus sign
you wanna make sure that the new battery goes in the same way
Here's the the negative side you'll see the band around it and here's the plus side.
Let's see if I can get closer without it getting blurred
okay there's the negative side and the plus side
is this side. It will have a plus on it.
I recommend getting the same battery as the one that came out. There are
substitutes
but sometimes the substitutes use different chemistry and some watches
are not tolerant of that
so the safest thing to do is to replace it with
exactly the same type okay again you wanna make sure your hands are clean oil
free
you wanna wipe the watch around here and wipe the battery
if there's any corrosion in here you want to remove it. I oftentimes use a
a cotton bud or something. I like get the paper type cotton bud, I
break the stick and I use the stick
to actually remove any corrosion and you want to remove the corrosion let
fall out of the watch You can also use a toothpick but be really really
careful you do not bendanything
or catch it on anything
but again get the corrosion out of there. I do not recommend using water or any
chemicals like that
can really make a mess of your watch so
just to take it out. If there's anything in there take it out dry
wipe the contact you can see one contact is here and the other contact is
over here
wipe them off carefully then
take a new battery and
insert the new battery into the watch like this
this one will snap in under those little fingers
It snaps in. You can see it's back in the original position
Replace this. Again taking care
the notch is in the right location
then check the
notch in the back make sure there's no hair dirt or anything around the
0-ring
set that side
into the watch so it's
lined up in there hold that down
and use your other hand to snap it into place
then you need to check around to make sure that the
the back is seated evenly all the way around
if it's up in one place then it's not properly seated you'll have to take it off
and do it again
so this one is OK and it's ready to go
if you have the screw type back
the common tool I like to use for that is
none other than needle nose pliers
I to set it down on a firm surface
something that is not a scratch the watch you have to make sure that the
pliers
straight up and down Press and turn
and this one is coming off rather easily. Don't slip because it will scrap the back of the
watch. Once it starts to turn
it's much easier to use your fingers. Apply pressure on both sides
and it will start rotating around it comes off
In this case the battery would be here. The battery is already gone
clean it up as
with the other watch. With this watch, you put the back
in place, screw it down evenly
do not cross thread it, that is important
once the back is seated, you just want to give it about
16 th of a turn. Not a quarter of a turn
about a 16th of a turn. You'll be able to see the back will be
seated all the way down the
still up a little bit
And that is how you replace
the battery in both the snap back type watch
and a screw type back watch
