Hi Matt, and welcome.

The short answer is: Yes, that is a high restoration cost. Unfortunately the Heuer you have in question is probably worth equal or less than the amount you have been quoted for repair. I'm no expert when it comes to precise pricing of restoration, but one thing that stands out for me is the quote for a new crystal... The mineral glass for your watch would be a standard size, available from any watch parts wholesaler for approx $2. (yes, two dollars) So quoting you 200 bucks is outrageous. At the most, $50, but here in the UK there is a large online watch parts company that sells standard glass for £0.99 - what's that, around $1.50.
Custon pusher assembly - again, I think your watchmaker is taking advantage, standard pushers should cost no more than a few dollars.

If I were you, I'd find a different watch repaired and have them look at it, the movement is a standard Valjoux works.
