It is sapphire.
The 'museum grade' bit may be adding a pinch of marketing licence though, but as Mr Christopher Ward himself has explained it in the past: "The crystal is still sapphire and it still has the anti-reflective properties of all our other watches… the application being on the underside. However the glass is further treated giving a polarising effect thus reducing the amount of light reflected. It is the same principle as that used to cover famous paintings and photographs inside museums and exhibition halls." Kevin - congrats on acquiring a rather lovely watch, very classy. Enjoy |
