Davidsen re-lumes the Fiddy dial to match his hands color (slightly lighter shade of C3 superluminova) plus he still uses a sapphire Fiddy xtal from an alternative xtal supplier which is a step above the standard Sapphire xtal on run-of-the-mill Fiddy reps you'll get from rep Cartel boys etc.
BTW, DSN Fiddy hands and the xtal on their own is worth the price difference, IMO.
