116718 Technical Sheets
Tony Axelzon from Sweden posted on a few of the watch boards some of the technical sheets that are available to Rolex watchmakers. Although these sheets are for the all gold GMT 116718 watch, they certainly seem applicable to any of the other GMT 11671x watch series.
These technical sheets show how the ceramic bezel operates, as well as verifying that there is antireflective coating on the both sides of the main crystal, but only below the cyclops.
