Just curious, Does ETA make the double chrono movement? Or is the modification done by in-house watchmaker?
I noticed that Porsche Design watch with double chrono movement at quite low price and wonder. While I know they are made by Eterna, I was wondering whether Eterna modified the movement, or are they finishing and fitting the standard ETA movement in there.
I THOUGHT all the double chrono movements were made in-house but the pricing seems to suggest otherwise.
