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 1900's 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, the 6536 used Tropic 18 (also T17).

There are 3 variations for a T19 tropic crystal, namely "Superdome", "Dome" &"Service Dome".

19 Superdome has the most rounded profile at the top.

The Superdome has the most light absorbed within the curved plexiglas. The first generation existed with the legandary Rolex #6536 James bond watch.

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

Superdome.
