Tip of the hat to old school

*Omega explains: "When NASA chose this watch, they requested a hesalite crystal, which, unlike a sapphire crystal, does not break into tiny fragments on impact. This feature is very important for astronauts, as the tiny fragments of a broken sapphire crystal would pose a danger in a zero-gravity environment."

Now *that* is preparation,. *That* is properly scoping out a project. And *that* is proper specification.

Like the reason they didn't use pencils (Russian gags aside) was because of the danger of graphite floating into electrical circuits. *That's* why the Apollo pens cost so much.
