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

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

Rolex SA. 

A plexiglas 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.

ref #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.
