Wrench with a small diameter

[jermy]

Hi,

I'm looking for a watch  back case opener wrench  "who have 3 jaws" which the min diameter is 10mm,

So far I have found (a wrench with 3 jaws) only 17mm

Also found tools with 2 jaws even less, but I'm after a wrench with 3 jaws...

Can someone direct me to such a wrench (if it exist at all)

TIA

never seen one go that small.
Maybe you should look into the caseballs. Essentially a sticky rubber ball.

Thanks for repelling

 What's the smallest you HAVE seen ?

Homemade? Is it for a special watch? i have a special one for Seiko casebacks. Made from 3 d printer. Has brass pins. I am sure someone can do a similar. of a Alu or nylon puck..

I had the same problem with a small ladys Cortebert.

Put the watch in a vice (I suppose it is too small to securely hold by hand) and use a small pair of tongs (pliers,clippers I don't know the exact word for it) that would fit in the back case cuttings. I'll try to take a photo tonight.

Can someone tell what's the smallest existing on the market ? (Is it actually 17MM ?)

Hi jermy, sorry, I don't think anyone has really been looking for something that small -- only you -- so chances are no one has that information (smaller wrench in the market). All I can say is that some people open the back of even divers with an old caliper...but again that's only 2 prongs!

Any specific reason it has to be 3?

Cheers,

Bob

It seams that way, I wasn't able find smaller than 17mm (with 3 jaws)

That's why I came here

I need it stable, it won't be with 2 jaws
