Hello everybody 'Lurgs' here welcome to my channel and today it's how to replace the battery on a
Casio digital watch this is for the Casio W753 but it should also be exactly the same procedure
for lots of other Casio digital watches so stick around even if this isn't your exact model
and I need this watch because I take it out surfing and it gives me tide times and I can
work out how long I've got left on the parking so we need to replace the battery in this make
sure you have a lovely cup of tea before after or during now I've just got this watch repair
kit which has got lots of different types of tools in it but I actually ended up using a tiny little
screwdriver that I got out of a Christmas cracker a few years ago take your miniature screwdriver
make sure it's a really good fit because you don't want to start damaging the head on the screw
and then just start undoing all four screws
whilst I'm doing that there's a link above now about how to keep your washing machine
hygienically fresh it's definitely worth running that program about every 30 washing cycles
okay that's the first screw removed now let's remove the other three
and I'll just speed this footage up now I've got reasonable size sausage
fingers so working with these tiny screws and this tiny watch is quite hard work
Just remove the back off gently put that down somewhere safe
now I've highlighted this here this is the rubber seal slash gasket try not to turn the
watch upside down because this gasket can fall out if it does just make sure you put it back in
properly and this helps keep the watch waterproof now we just need to remove this
plastic sticker here just stops it shorting out on the back of the watch again put that
somewhere safe that needs to go back in exactly the same position and there is the watch battery
there it's a CR2025 3 volts now the easiest way to get access to this is just take your strap
and just do it up backwards just so it's easier to remove the battery now you don't need to say that
the watch has actually come back on it's probably because I've fiddled with the battery slightly
but it still does need replacing because I've had this watch for over 10 years and it's never had
the battery replaced now what you need to do is take a needle or a really small fine point
and you're just sticking it in a hole in this point here and then just maneuvering it and
trying to wedge it outwards so you're kind of trying to pop it outwards
there we go now you can just slide the battery out be careful underneath this because you've just got
a small plastic washer here make sure you put that back in I'm just going to slide that back in there
whilst I'm doing that there's a link above now about what
to do if your dishwasher is not draining water
right that plastic washer is back in now what we need to do is take your brand new CR2025 battery
make sure you definitely get a good quality one there's no point in buying a cheap one from one
of these cheapo places where the batteries are almost out of date when you first buy
them
now what you do is you literally just slide that underneath
once that's in position then just take your sausage thumb
and just push it down until it clips back in
what do you call a Judge with no thumbs? Justice Fingers,
that's my one joke for the day I'm not going to make it as a comedian right remember to put the
sticker back on this has to go in exactly the same position so you've got those two little
indentations at the side about five o'clock there which it needs to cover just push that back on
that's all looking good the watch is fired up
I'm just checking the rubber gasket there making sure it hasn't moved that all looks good
now let's put the back on whilst I'm doing that there's a link above now about how to
test your car battery using a Multimeter in these times of lockdown when you're not using
your car match it's definitely worth checking your battery quite often now take one of your screws
these are very very small so I'm having real problems here with my sausage fingers
and I've had to put my glasses on
just line that up
now if this doesn't feel like it's going onto the thread don't force it because
they're tiny little screws you do not want to damage the thread so make sure it goes
in nice and smooth and don't just do one up really really tight before you do the others
put them all in slowly and then tighten them up as if you were doing a car wheel just do opposites
and just gently do them up on each corner so it goes down nice and uniform all the way around
whilst I'm doing that there's a link above now about how to disconnect a washing machine
in case you're getting ready to install a brand new one so tighten those up really
nice and tight as tight as you can get them now I can't guarantee that your watch will still be
waterproof to 100 meters but it should still be waterproof and we'll find out if mine is
at the end of this video now I just need to set the time and the tide graphs and the moon phases
and this is the instruction booklet here I won't go through this with you and I'm going to set the
date and time the tide graphs and the moon phases and then test it out in the water just taking my
watch out surfing this will be a good test right let's go this will be a good test because it takes
a right hammering. [Point Break quote] 'We'll get him when he comes back in...he's not coming back'
and this is after the surf session and my watch
is still working absolutely fabulous I am well pleased with that great stuff great stuff
