I don't get it. I'm no Schwarzenegger, but I have some way-heavy watches. My Omega Planet Ocean on bracelet is 220g all up - that's gotta be heavier than the Double Split. Most Panerais (even on leather straps) would be the same weight or heavier. I never notice the extra weight when wearing my Omega.
A 220g wristwatch is nothing compared to the actual weight of one's upper limb, which is probably around the 5-8kg mark. Just the forearm alone would probably weigh 2-3kg. So we are talking about maybe a 5-10% increase in effective weight when wearing a very heavy watch.
The only real disadvantage of a heavy watch, particularly one on a strap, is that the watch may feel unbalanced on the wrist, with a tendency to slide radially around the wrist, putting pressure on the forearm bones. This is surely just a matter of adjusting the strap so this doesn't occur.
Any Double Split owners out there who feel inconvenienced by the weight of their watch can engage my services as a wearer-by-proxy.
