Watch crystal types

[luiazazrambo]

Dear Watch and Clockmakers,

I am organizing some of my watch "crystals" and I am not sure how to call some of them, not even sure if there is a name for them. What do you think? And does any watch would came to your mind which would have one of these?

Fancy shaped oval I assume.

Domed, with calendar window:

 

Cushion?

These ones have no sidewall but a flat bottom, dunno how to call them:

Tonneau?

These ones have a pattern outside:

These ones have a flat top:

Well this is fancy shaped again, leaf?

And these ones have a pattern inside:

Best regards,

Lui

A good move might be to reference against the CousinsUK info e.g.

https://www.cousinsuk.com/document/category/acrylic-shaped-watch-glasses

or

 https://www.cousinsuk.com/category/acrylic-watch-glasses

This will help you decide between barrel, bale, oval etc.

Those pattern ones are called faceted and, for Sternkreuz, come under their CP range which they term 'saphir imitation'. 

There is the complete Sternkreuz catalogue available at http://www.sternkreuz.de/accordion/assets/Sternkreuz_Gesamtkatalog G22.pdf too which may be of use.
