What's a restoration worth?

Folks, I know this is a Rolex forum, but I'm looking at a 60s model vintage compressor watch that has been fully restored. I'm negotiating a price vs a another in similar condition but with no service history.

Provided that all else is equal in regards to condition of the case, crystal, dial, etc., what might a full restoration on a vintage watch like this be worth?

$100? $200 $300

I know that service and restoration will be different for every watch depending on its condition and movement, but I'm trying to get a realistic idea of how much more the restored watch is worth. Not to mention the hassle of actually having it done.

I guess the better question to ask is: How much more would you pay for a watch that has just been fully restored?

Any feedback is appreciated and a photo of the movement during restoration is included below. Thanks in advance.

Many watches are not worth the effort or cost of restoration and doing so may boil down to "hobby", "experience", or the watch has sentimental/personal value.

Regardless of the cost expended the end product is still only worth the market value

I understand this. That was not my question. My question was what would a full restoration cost in terms of real dollars?
