Originally inspired from a technique used widely in the aerospace industry, the signature coating provides high impact resistance whilst maintaining its polished surface finish. The convex sapphire crystal is treated with nine layers of anti-reflective coating applied to both sides of the glass for increased legibility. The high standard of finish and attention to detail can be seen in the meticulous machining of the three-part cases which take considerable time and skill to apply.
