Very interesting. I wonder if this is how all classic 3717's (complete from the factory) will look in the future then - or if it's just the replacement parts ATM? Spoke to my local AD yesterday and his most recent delivery of 3717's from IWC still had the silver centre subdial hands. And he hasn't heard anything about this kind of update yet so I guess only time will tell..
Personally, I love the small silver centre detail. However, if it turns out to be a real model update on the gens, then it will be a easy mod to make the rep hands very accurate that's for sure..
