Out of the box...DSN's are really good.
Great looking anthracite dial which is already superlumed, closest to gen hands with smaller GMT arrow tip, nice ARed crystal with a 7mm cyclops, thicker than regular cartel date font....etc
The only things I'd probably change would be the caseback which DSN's is more like it was etched than engraved. I would possibly get a Lello datewheel for it if I was really picky.
Other than that....DSN's 089 is great out of the box.
