Both versions of recent rep GMTs have independent GMT hands. ICHS vs CHS primarily means two things.
ICHS - GMT hand is on the bottom of the stack, unlike the gen (hence the acronym INCORRECT hand stack). It has a reliable 2836 movement with GMT bits that is easy to work on with readily available parts.
CHS - Hour hand is on the bottom like the gen. The movement is a base 2824 with add on Chinese jury rigged parts to allow for the CHS. The movement is delicate and must be set and operated in a certain way to keep from breaking. When it does, replacement movements or parts are not available.
The GMT hand is only near the hour hand for 2 hours a day. In 30 years of owning a gen Rolex GMT Master, no one has ever noticed or asked about my hand stack. I don't own and would not buy a CHS rep except to tear it down out of curiosity.

One little 10 cent spring turns your whole CHS watch into a paperweight.
