If you've ever worked on more than a very few Tektronix TM-500 series modules, you are well aware of the favorite epoxy dipped tantalum capacitor failure mode... very low resistance dead short... usually ending up in a charred stinky black blob. Whatever manufacturer they chose... was the wrong one.
There are wet-slug tantalum caps out there. Usually hermetically sealed military grade units.
For the clock, I'd use whatever cap came to hand. I would not go out of my way to find some swoopty-do new fangled replacement. It's a Heathkit, not a space qualified doomaflotchy.
