Sub 16800 with wrong dial from factory?

[amv1981]

Hi all,

New to the forum, but not to the watch game. Noob when it comes to Rolex watches though:)

Rolex Sub 16800 with serial 86XXXXX (my 1985) appears to have mixed dial and crown, and to my knowledge it is a steel version with mods.

But I am having a hard time finding similar dials on other subs. What could this mix/hybrid be made from?

I have the original steel bracelet which makes me believe its an all steel version from the beginning.
