Acrylic Glass, Savonette/Hunter (SAV)
Only available in acrylic/plastic. Very thin with a very shallow dome for use on the inside of pocket watches with a cover that closes.
When glass hunter glasses were made, different heights were available. Now only acrylic glasses are available, and only in one height. They may not be suitable if the pocket watch has high hands. Unfortunately there is no solution to this issue. We only have savonette/hunter glasses in acrylic and in one dome height.
