Alternate options vs seadweller 116600?

[KeepTime]

I’m getting really close to pulling the trigger on a lightly use 18’ seadweller 116600. Before I do I wanted to look for other options that I may be missing... Heres my draws to the sd4000. I have a Batman, and 2 no date subs one on a rubberb and the other I am looking to replace with this sd4000.

These are just personal preference to help you understand why this is my current pick and could help you steer me into a different direction.

I like that they only made it a short period
40mm is a plus for me
It’s different in that the date has no cyclops... a last for Rolex possibly?
Dial is matte black which is nice for a change.
Lugs/ case wear slightly smaller than a 40mm sub
