I have to agree that DSN uses superior stuff for the lume. I have that 089 and I can confirm that it's as good as Superluminova C3, if not it IS the real thing.
Anyway slightly out of topic, just a wishful thought on DSN Ti model, the engraving on the caseback on Ti model can be further improved. I would say that it's more like an etching instead of engraving but nevertheless, you are getting a lot for your money by going DSN route. This engraving is NOT an issue on his SS/PVD case.
Wish that DSN uses better crystal
That cyclop on le cartel's looks really good.
