Don't be fooled by the extremely misleading name though. The coating aint nothing like diamond. If you plan to wear the watch regularily it will eventually scratch. Some people like the look when it gets more worn, just good to be aware it will eventually wear off if you don't baby the watch.
I have been quite impressed with the TH DLC coating on both my pvd aquaracers, I’ve been wearing the calibre 16 since 2014 and the night diver for 2.5 years. I’m quite careful with them, removing them before any manual labour, but both have had a lot of wear, including a month straight for the night diver when I went on vacation and a couple of years of business travel with the c16.
Both are only showing a little polishing on the corners, no chips or scuffs. I’d say the photo above is either a fake or the owner was careless or unlucky.

C16 Full Black top is in pretty good condition for a 9yo watch:
Breitling is the same shit, looked at Blckbird 44's recently for example. Look at the crown on this one, I suppose simply worn off from frequent use of the crown
Here is another one showing how the edges of the case and bezel is starting to show on this one
Based on my Avenger, which I’ve owned for just under a year, I think the Breitling coating is more fragile. Mine is not showing polishing on the edges underneath like the TAGs, but I have scratched the coating on one of the lugs and it’s starting to polish on the edges of raised sections on the bezel:
The Breitling pvd is a different shade, grey not black, and as the titanium oxidises where it’s scratched, it goes from standing out and looking terrible, to looking ok. Overall I still think it looks good, and suspect it will age quite nicely, although obviously the value will drop a lot as it gets more beaten up.
I need a lie down
