What an anti-reflective coating?
Some manufacturers coat the inside and or outside of the crystal of their watches with a thin film that cuts down on the reflections visible when viewing the dial. This anti-reflective film sometimes gives a slight blue tint to the crystal. Manufacturers like Breitling , Zenith and Panerai use this coating extensively through their product line. The effect of the coating is that the watch crystal appears to be invisible at certain viewing angles. Also the watch is viewable in outdoor setting where without the coating the glare would make reading the dial difficult. Counterfeit Watch Missing anti-reflective coating is one of the easiest way to spot a counterfeit. Move the watch around and view it from different angles. If the crystal remains glossy and reflective from various angles then it does not have the coating. This is great way to spot fake Panerais and Breitlings as they are great proponents of the coating.
