Usually it's one answer from each article so I'd go for mother of pearl based on:
https://en.worldtempus.com/article/watches/trends-and-style/longines-the-longines-master-collection-the-moon-on-her-wrist-30529.html 
which suggests white of mother of pearl is the default and the other two are options in the range.

Then https://en.worldtempus.com/watch-brand/longines-81 is the page that tells you they were founded in 1832 so 190 years
