Crystal size vs gasket

[Khan]

Hi Does the glass diameter has to be exact same size as the inner diameter of a glass gasket? For instance if I order a L-gasket with inner diameter 29.4 mm, should glass be 29.4 or 29.5? 

Kind regards

I assume you mean actual glass, not acrylic, and a plastic gasket?

The glass should be 0.1 mm wider than the inner diameter of the gasket.

On common, contemporary watches, crystal sizes not ending .0 or .5 are rarely used. So you start looking at the glass size, not the gasket.

Not always. I normally fit them being of the same size.

And does the plastic gasket need to be lubricated with silicone Grease?

No, never.
