Hi there,
You said this pocket watch is missing a crown but it runs and keeps time. So the missing crown has nothing to do with winding mechanism, right?! The other crown is to set alarm. This is a pocket watch with alarm
To maximize your return and value, it's the best to fix it. But if the repair cost is not reasonable to you, don't spend the money, because you could always sell it "as is" on eBay. Total cost to me to repair something like this, as I see; it's missing Stem and Crown is appx. $25 but it might cost you much more. So, think about which route you want to take by checking your resources
To place a value on the watch, first you need to identify the caliber and metal content. This metal doesn't seem to be gold. But you need to make sure in two ways. First identify the metal content markings, second if you can not find any metal content markings, you need to test the metal to make sure, you're not selling a gold pocket watch for base metal value
Once, you have gone through above two simple steps, selling road is easy and clear. There is an interest out there for mechanical alarm watches because no one is making them anymore. Research a price and post it the best you could, including readings of all markings and a picture of the movement. You could always let the watch enthusiasts make their own evaluation by posting the watch on a 10 day auction with reasonable initial value
Good luck to you.
If you have anymore questions, please ask!
