I am thinking about buying this http://www.timeshops.net/IWC1213_-_IWC_Pilot_Chrono_Black_Dial_SS_LT_-_Asian_7750_28800BPH_180065-72.htm IWC 3717. Does anyone know if this is the best version out there?
Is says is has double AR, but will it still be a huge improvement to get a double AR from Chieftang?
