Penetrating oil, of your choice, and a pair of duck bill pliers, the flat kind with no texture, to grab the hub of the pointer. Leave the oil on it overnight, then add a little more, then leave that for a few hours, then tap the center sharply with a screwdriver handle, then grab the hub of the pointer (not the needle) and give it a twist, once it moves then pull and twist at the same time. If it does not loosen up and come out I don't know what to suggest, maybe wrap a string around the hub of the pointer and see if that will give you some purchase, or work it's way between the pointer and the shaft.
Regards
Arran
