Mineral Glass Replacement - Gasket

[easthammer]

I need help as I normally replace Acrylic glass. I have a broken glass which was mineral glass and 1mm thick. Its to fit a case which measures 29.55mm.

What size glass and gasket should I order? 

I think i should order the below - 

MSI Sternkreuz 29.5

MSI295 - cousins

Is the gasket still in place and is the 29.55mm inside the gasket?

Edit

Can you post photos to confirm it's and I-Ring Gasket.

Not sure if i need to think about colour also as it is for a gold case

Are you sure that's a gasket for a flat crystal?
