[MARVEL] Exactly how powerful are the Watchers?

They're supposed to be all-knowing beings, right? 

• Are they omnipotent?

• Are they watching all universes? Ultimate, 616, MAX, etc?

• Do they exist on a seperate plane apart from all universes or do they exist in each universe like essential people such as Spider-Man and Wolverine.

• Basically, what are they capable of?

Prior to their ascension to what we know of them as now, they were a humble but brilliant race, like humans,  who after thousands of years of study, discovered a process to turn their entire bodies into pure energy, rendering the need to breath, eat or drink useless and essentially becoming immortal. They didn't gain anything else from the process. No energy beams or mental powers. Arguably, they already possessed the power to teleport (an old scientific invention). They no longer evolved. They grew bored. They determined that they should be a force of good in the universe and assist other, sentient, races in their evolution.

The first planet they visited was a race of lizard men. They taught the lizard men all the good/helpful things there was to know about what nuclear energy could do, then departed feeling fulfilled. When they returned to see how far the race had jumped thanks to the advancements the Watchers taught them, they found a world scarred. Because the lizards had never struggled and studied the dangers of nuclear energy, they used it in bombs and weapons and incited a nuclear winter that killed all their people.

The Watchers, at that point vowed never to interfere again. They would only watch and observe events that could help increase their knowledge of the universe. They aren't all-knowing, all-powerful nor are they mortal. They are vastly intelligent and made of pure energy and can teleport. They are in tune with the universal powers Eternity and Infinity so they know where to go for important events which almost always has to do with Galactus.
