Source for a New 16618 Bezel Insert?

[enginerd]

I acquired a 16618 last week, and I love everything about it except for one thing. The bezel insert appears to be rotting from the inside out. It's much more noticeable in photos than on the wrist. The gold font is also quite faded, at least compared to others I see.

Is this something I could just take into my AD to ask for a new part? I assume they'd keep my old one, and I know how you guys get about your flat 4s. Apparently that was a thing with 16618 Subs too (I had no idea).

Should I just have them swap it out, or should I "lose" mine and try and get another? I'm fairly handy with bezel insert swaps.
