I think the same will happen.
I accidentally bang my watch too. However its sapphire and it is still flawless after 5 years of "banging".
The problem with any watch is that the screen is always facing outwards and is vulnerable to dings and bangs. The quandary with sapphire is the added cost. Can you justify the added cost to an item that you will probably upgrade in a year? If you don't plan on upgrading next year then definitely get the sapphire crystal.
I will probably upgrade the SS model I ordered if next years SS version is compelling enough. I figure, no ... I know, that the crystal on the SS will be perfect. I can't say that for the Sport model based on my experience with non sapphire watches.
I am thinking that the SS model will hold more value than the Sport model when it comes time to sell it because it has a excellent chance of having a "perfect" crystal as opposed to the Sport. Then I will do what I have done in the past to get a new iPhone every year, and use the funds from the sold one to defray from the cost of the new one.
Of course thats just my opinion, I could be wrong.
