DayDate 40 crown out, O-ring?

Quick question for all the DD 40 owners out there. When I pull out the crown to wind my DD I do not see a black rubber o-ring like I see in my Daytona and DSSD. Can you all confirm the presence or absence of this o-ring? Thanks!!!

I believe that it is one of the gaskets which helps keep the watch water resistant.

Not 100% sure but I think the DD has a twin lock and the diver are triple lock. So on the twin lock you won't see the O ring on the triple lock you will. Just my .02.
