For goodness' sake, we're talking about a simple flip of the penknife (albeit carefully) to get the original Rolex GMT bezel off and replaced with the Rolex Cerachrom bezel. It ain't rocket science and it doesn't touch the innards. As long as it rocks the TS' boat, I'd say, "Go for it!". Heck, this could be the motivation for the TS to go from the 116710LN to 116719BLRO. Last I checked, there was a RM80k price difference between them, so I think that it was a great way for the TS to move towards his dream with a first step forward (bezel mod). And a real WIS would be able to tell the difference straightaway given the GMT hand, so he ain't cheating anyone.
To equate that such a mod would then cheapen the watch to a "cheap fake Rolex" was simply hilarious. It all depends on your social standing and crowd that you mix with. If the TS would show his watch to me, I would have given him a pat on the back. If a chap has yet to attain a certain level of maturity and financial independence (and discounting the fact that he had rich parents to support his horology hobby), I would opine that his immediate known circle would simply assume that he was wearing a "cheap fake Rolex" even if he was actually wearing a genuine one.
If we were talking about Seiko SKX, and the TS was asking about bezel, dial, hands' mods from Seikoboy, Dagaz, etc I was pretty sure that most would have given him the encouragement to go ahead, and then praised him for the creativity. So why the double standards here?
