this is supposed to be an Old Omega Seamaster. There is no grip at the
back. Does not seem like a snap-on back.

There are two notches at the rim of the back cover but it looks like
it was made by the previous guy trying to open it with a grip vise.

The picture is here:

its not really a snap-on back, its more a pressed in back, a snap-on back
usually is metal to metal fit with a "O"ring seal in between to keep the
water out.

these Omega's use a "tupperware" gasket made of polyethylene?, the gasket
is fitted into the case and the back is pressed into that much the same
way a mineral crystal is fitted into a gasket

so yeah, the backs in these Omegas are a very tight fit, just find the
notch and use a strong case knife and it will come off.

word of warning when replacing the back, use a case press to make sure
the back is fitted square on, don't deform the gasket because if you do
the back will not stay on and you will have to replace the gasket (if you
can still get them)

Thanks. Just opened it. Good genuine Omega movement. But the case(lug)
is beyond repairs.

any idea where to find a replacement case?

only if Omega have any in stock, otherwise get a casemaker to rebuild the
lugs and replate the case
