I had a stuck Seiko quartz case back. Tiny slot for leverage with no edge remaining.

Clean up everything with Acetone so the super glue sticks.

Apply a small amount of super glue on the back and set the nut or bolt. I prefer a bolt head to provide more surface area and you have a built in handle for removal.

Wrench it off slowly (lefty loosy) and viola!
Now to remove the case back from the bolt. Liberal soaking in acetone and it slips off.

There you have it. Case back removed. Bigger case back = bigger nut. Give it a try.......on a beater first ;-)

 

Why didn't you try scissors first before going to all that trouble?

 

Scissors?

 

When I lived Down Under, a twenty-cent coin was the perfect size for those case backs. Or maybe it was a ten - it's been too long. A coin!

 

Always thought it was 10 yen, at least for cameras.

 

Nickel, quarter, screw driver didn't work. It was stuck with the gooie gasket condition.
Granted, I didn't try scissors

 

It's a joke that goes back to the early days, where some idiot used scissors on the back of a Rolex in a YouTube video.

 

It's widespread now, even here.

Love this thread redpcar

I first heard about this 10 years and it was apparently a joke reply on WUS. Someone took the poster seriously and used this method to open a stuck Seiko case back.

I've used this method many times over the years without fail.

 

You guy would have been a valuable addition to the Apollo 13 ground crew!

 

Hahaha, Best case open practice so far!

 

I'm really uncomfortable with the picture you use for your avatar.
Even though I'm dead, I still have feelings.

 

Hey come on, what are you taking about? You poor slobs! Why don't you go out and get a job for crying out loud? I've been working since I was 9 years old. Yeah, sure, look where I am today, I'm right on top!

 

I might have to go incognito.

 

MIG welder works better.

 

Never had a stuck case back

 

not trying to hijack........I had an indy call me to pick up my x-33 a bunch of years ago, he snapped three of the case back screw heads off on a battery change and didn't want to go any further. He didn't charge me anything....

 

Now you've got the back off, cleaned up and that silly bolt off, why don't you either get someone to braze a wing nut on the back OR grind out the screwdriver slot so you've got a lot more leverage in future?
