I have the IWC Portuguese Chrono. I have several JLCs -- Master Moon, Master Geographic, Master Ultra Thin, Reverso Grande Date. My own experience was the IWC captures the heart with the dial -- it is an impulse buy. However, all my JLC grew on me. I would not part with any of the JLC but I am entertaining letting go of the IWC, even though it is less than 6 months old.
Just sharing my own experience.
