The Submariner, on the other hand, has featured crown guards since 1959. And do you know why? Because they protect the crown. If you were actually to put a Sub through its paces, diving, adventuring, what have you, it’s possible to damage the crown if you aren’t careful. Guarding it on both sides is a way to keep such damage from occurring. The same goes for the ceramic bezel which, unlike Tudor’s cool and vintage aluminum, is effectively scratch-resistant and will never, ever fade.
