Asthetic differences between Rolex SD and Sub

[NickHKent]

Wondering if any Rolex experts can point out the differences between these that my untrained and inexperienced eye cannot spot?

Thanks

The SD is a thicker watch due to it's deeper depth rating.
The SD has the Helium release valve on the 9 o'clock side of the watch.
The SD doesn't have the cyclops over the date.

Can't think of any other aesthetic differences beyond the printing on the dial.

I always had you down as a real Rolex expert Luke

I can only add that some Subs don't have a date & some have green bezels.

The seadweller has the gas escape valve on the side
Seadweller weighs substantially more and has a smaller diameter dial
the glass on the seadweller also stands proud of the bezel ( thicker glass)
I own both a green sub and a seadweller and after the seadweller the sub feels lightweight
if i had to keep one it would be the seadweller no question
