Apple Watch and Data

[Halamire]

How much cellular data do you think the apple watch will use? Do you think it's going to be a constant drain since it's refreshing everything at a constant rate or what? Kind of wish I still had my unlimited now!

I wouldn't worry to much about this. I doubt it's more compared to what you already got of usage with your iPhone. Keep in mind that iPhone does the same as what you mention now: it constantly refreshes for new content. It's not different with your Apple Watch paired, except that the Watch uses Bluetooth to connect with the iPhone to retrieve to content.

So again, there shouldn't be an actual noticeable difference.
