So, I collected my Tridor DD back from Rolex Authorized service today. Looks good, except there's a slight gap between the case and the crown. It wasn't there before the service and none of my other Rolexes have it. Shouldn't the case be flush with the crown? If so, then I'll have to take it back. Attached are a couple of photos. A first world problem, I know. Thanks, folks.

You didn’t mention so I have to ask. Did you try screwing it in?

Yes, I did. The photos depict the crown screwed down all the way.

Maybe the new O-ring is stiff? Just spitballing

No, the crown shouldn't be 'flush', or touch the case.
It only needs to be finger tight, and just enough to snug into the rubber O-ring.
By snug, I don't mean tight either. Biggest mistake you can make is try to over tighten these, as all you do is crush the rubber seal. Just like in the plumbing trade, finger tight on rubber/teflon connections + a quarter turn. On a watch, just a light snug touch is all that is needed.

Interesting in looks, seems like the Tudors. Maybe thicker gaskets after being replaced

As mentioned, if the crown hits the case the gasket in the crown cannot seal.

The gasket is at the top of the crown, and seals against the top of the tube so there needs to be clearance at the bottom, to allow the top to seat properly.

The twinlock is on the left and you can see the red gasket inside the crown.

Normal, you have a new gasket.

The crown also tapers down at the bottom, towards the case, so no matter what it'll look like there's a big gap that doesn't actually exist.
