Hi, I’m looking at procuring either an Omega Sapphire Sandwich or one with the Hesalite covering. My question pertains to space flight. I’m planning on taking a trip to space with Blue Origin and wondering is the Sapphire version allowed up there? I know that hesalite doesn’t shatter like sapphire, which is why it’s NASA certified. However, I just love the caseback on the sapphire sandwich and the ability to watch the movement of the engine. Which would you recommend?
For actual going up in space, Hesalite.
For earthbound me, sapphire.
For someone rich enough for private space flight, both.
