I noticed right off the bat the sapphire crystal has some sort of coating on it. I know this can help with performance but it can become damaged even on high end watches. Especially ones meant to be used roughly. Even high end mechanical watches sometimes only have a coating on the interior surface of the crystal, which isn’t relevant on the Ultra.

Anyone know what this coating is? Anyone damage it already?

Anti glare coating. I haven't had a problem since my opening day S0. That coating came off within the first month.
