Stubborn case backs

I am trying to open the case back on my Invicta and having all sorts of
problems. I can't physically hold the back when I use the wrench on it.
What do the pros do? I am thinking of nailing a couple of nails into
my workbench for the watch to sit in while I torque the case back
opener. Better suggestions?

I suggest the following:

1. Place Invicta behind your rear tire.
2. Back up.
3. Buy a Rolex.

Or buy a new Invicta every year for the rest of my life and invest the
difference and be way better off financially.

Whhaaaa ? And deprive Rolex form ripping you off every 5 years to the tune of
the price of 5 Invictas ? You should be ashamed of yourself.

Those yacht races and glossy adverts in national geographic don't pay

well I can open most screw back cases just by holding the case, but on
the really torquey cases I use my Bergeon 5700

you can buy a simple case holder that clamps in a vise, has 4 round pegs
to hold the case without marking it, see item CWR175.00 here

I've got a chinese copy of the Bergeon opener which grips the case back
quite well. A holder with nylon pins is just the ticket for holding the
watch so I can put on some torque.

Cheers mate.

Hey!
What about getting real ignerrant and holding it with channel lock
pliers with a stanky dirty old rag in the jaws. Personally I would
never be so crude as to attempt this but I heard once of a guy doing
it.

And don't forget you can always drill a couple of holes in the back for the
prongs on that little back remover thang-a-ma-jig to fit into. They don't
slip and skin your fingers that way.

As tempting as your suggestion was I ended up with the nylon pin holder
and stuck that in my bench vice. Worked a treat and cost less than 8
bucks on ebay.

Well, at least with the rag covering it all you would be spared seeing the
crown/pipe getting sheared off or bent, if you slip. :)

The simplest that i may do is to put the case between the loosely closed up
jaws of my smooth faced bench vice(any vice with aluminium or similar jaw
covers on will suffice). The case will twist, stop and hold on it's opposing
corners. You'd only want to do that with stronger cases though and only within
reason.
