IWC

I hope ...

 

you are not under an impression watches with double barrels are more accurate.  It is not likely to be true.

I don't know why IWC does not pursue two barrels, but I feel there is no need for it.  The 7-day movement is a large movement (nearly filled up the whole case) thus has more area on the movement to fit one barrel to provide 7 day power.

From my observations, double-barrels are utilised due to space constraint.
