When you compare this reference (IW328104) against the black ceramic version that shares the same case dimension, you’ll notice the price is much higher – $8,100 versus $6,350. While that’s not solely down to case color, the differences might not be enough for most people to notice or feel that the upcharge is warranted.
The new white ceramic Top Gun now features 100m of water resistance versus 60m of the predecessor. While both watches feature a soft-iron inner case for anti-magnetism, inside that case is a newer movement, though the specifications largely seem the same from what I can tell. Both automatic movements beat at 28,800vph and have 120 hours of power reserve. I’ve reached out to IWC to see if there’s more that I’m missing.
