Sapphire is extremely hard; it is almost as hard as Diamond and is virtually none scratch.
On the "Mohs scale", Glass is 6, Sapphire is 9 and Diamond is 10.
The Sapphire ones we fit are crystal clear, so look exactly the same as glass.
The Sapphire crystal price is for a round and flat one. Domed ones please email us for a price.
For a genuine Seiko Sapphire Crystal your watch MUST say Sapphire or Sapphlex on the rear case (some are very expensive).
Please email us for a price, with the full calibre number that is on the rear case.
