Have you found the oleophobic coating to be as resistant to scratching?
My concern would be if somebody buys the sapphire because it doesn’t scratch easy, yet the coating does. The look of the watch will still be impaired if that is the case
Coatings all wear off over time, and over time can acquire micro-scratches from normal use. i.e if there is dust or other particles on the watch, or your finger, the pressure from using the AW screen can have a "sand paper: effect.
The difference between AW sapphire and glass is would be that on sapphire, the scratches would be in the oleophobic coating; with glass, the scratches could be in the glass itself.
On a traditional watch, we do not use our finger on the crystal to operate the watch. But cleaning a watch crystal, even sapphire, even by simply rubbing with a micro-fiber cloth, can have the same "sand paper" effect. Especially if there is an AR coating.
For that reason, many watch enthusiasts, and most professional watch makers, recommend rinsing a watch off, or using a can of compressed air, before using anything to rub on the crystal.

Even if It’s the oleophobic coating though is still not very good cosmetically. It’s not like u can renew the coating so for all intent and purposes the watch looks scratched.
True, it's a trade off. For that reason, many traditional watch users prefer no external AR coating, at the expense of more glare and occasion reduced readability in certain light. But the oleophobic coating wears off - some say in about a year. What's left will depend on what's underneath. Sapphire is better in that regard.
It does not seem like, given the bonding process between the display and the "glass" (sapphire or glass) on the AW, there is any option except the exterior of the glass to place a AR coating.
There is a difference between micro-scratches and an actual scratch. Something hard enough to leave a clearly visible scratch in the oleophobic coating is more likely to also scratch glass vs sapphire.
[doublepost=1546267062][/doublepost]Reading more posts on this topic, one thing I'm finding is some these scratches on sapphire, micro and otherwise, turn out to be cracks. Many of these pre-date the version 4.
I'm new to AW's, so I don't know all the various features and when they about. I'm wondering about the pressure sensitive screen. Sapphire is not flexible. Under pressure it can crack.
For this reason, there is quite a bit of debate on dive watches between sapphire and other materials. Even through the 1980's and 90's, many divers for military use used plexiglass. Sure, they scratched easily, but would not crack and let water in. Back then, a dive watch was all they had, so this could be life or death. In traditional watches, crystals are easy to replace, and plexiglass was much cheaper then sapphire. Plus when sapphire fails, water getting in means replacing dial, hands, and movement.
Under diving pressure, sometimes all it takes is a small knock to shatter sapphire. Plexiglass, and Seiko's Hardex, can take a more substantial hit before cracking. It's more likely to gouge out a divot before cracking.
My take on the AW: I don't plan to use the pressure sensitive feature on my sapphire SS S4. I don't think there is anything I need to do that I can't get to via another method.
