What is a Rolex Superdome, dome or service cristal dome ?

These terms refer to the different variations of a plexiglass or tropic crystal made by

Rolex SA. 

A plexiglass or tropic crystal is a transparent weather resistant thermoplastic that is

used on wristwatches, as a protective cover over the dial.

Plexiglas have been used by watch companies worldwide from as early as the

1900s till today.

Since sapphire crystals were available during the mid-1980s, watch companies have switched over.

For vintage collectors, plexiglass is still very much relevant in the 2010s and will

continue to do so in time to come. 

A Rolex Submariner Ref 5513 uses a tropic crystal T-19.

There are 3 variations for a T19 tropic crystal, namely Superdome, Dome and

Service Dome.

19 Superdome has the most rounded profile at the top.

The Superdome has the most light absorbed within the curved plexiglass.

This is due to the gradual curve (or stepped-up effect) of the dome shape on the

Superdome.
