AP's forged carbon Team Alinghi Chronograph was quite polarizing and radical when it launched. Audacity at its finest, IMO. I would welcome a new Royal Oak Offshore in this vein. Not necessarily a nautical or racing them, but something that freshly design...  

And I agree.

Your AP, it is Arnold’s watch. On the net, there is a video how AP produce these carbon cases.

And loved it, despite it was relatively not comfortable on my wrist. ...  

The watch looks great on day one, the problem is how the carbon ages over time and all the sharp edges of the case and bezel become rounded. That’s not an aesthetic to my taste, so I went with the rose gold case version and a new carbon bezel, which I lov... 

Has the durability of the carbon cases changed in any way over time?

I believe the latest compound of carbon that AP uses today is much more durable. Perhaps someone more knowledgeable than me could expand on that and highlight the developments over the past thirteen years (I think the Alinghi was first released in 2007?).... 

and it ran me around $1,300 if I remember correctly. In the grander scheme of things, I didn’t think that was too bad. Now, the price of a replacement case may be another story, I have no idea.

That would make sense as the bezel is made of solid rose gold with a rubber covering and the price of gold would make it more expensive than the carbon bezel.
