Hi all,
I need to change the battery on my 5Y23-8A11 SQ.
Can you tell me if I need a special tool to open up the back or can I use a more common household tool?
Thanks.

There are actual caseback tools for opening these watches.. First slip with a household tool will put giant scratches in the caseback and in turn lessen the value of the watch.

Search for "case back opening tool" It's probably best to use a Jaxa type tool with three adjustable prongs.

Thanks guys. Not the answer I was hoping for unfortunately.
My battery just died and I'm in West Africa at the moment! Oh well, I'll see if I can get a Jaxa tool or something here locally. The new battery is in hand...

I was caught out with a stopped 7S26 whilst travelling abroad - I managed to buy a pair of 90 degree circlip pliers which did the job. Go to the local tool shop -you're sure to find something similar.

wrap duct tape around your palm sticky side out, press and twist......

I used this for two weeks

snap ring pliers but very gently not to .......
" SLIP ".
Please........... be very careful and hold the watch firmly and take your time doing it

I like this one at the mo for the MacGyver case opening tool.... If it can't be fixed using duct tape.... it's not worth fixing :grin:

Thanks guys!
There's an automotive shop quite nearby. I'll see about the snap ring pliers and report back. And yes, I'll be very careful...

I've had very good luck with the duct tape. as well. Although, I make a big ball of it like the rubber case opening balls.

Snap ring = Circlip (like I said), and I'd be inclined to use the forged type, not the ones made from stamped plate!!

What are these balls like folk are talking about? I've even had my proper tool slip now and then but no scratches yet luckily

Duct tape ball

Well the shop didn't have a pair of pliers that would fit, so I tried the sticky duct tape ball "tool". Fantastic idea - It worked out really well! I made a ball about 2" in diameter. (50mm) The new battery is now in. Should be good for 3 more years...
Thanks for the tip!
