So since DSN is lacking in E mvmnts for the fiddy, who has the most accurate out of the box fiddy... i can see that several dealers have the e series fiddys available, however i haven't contacted them regarding stock yet..
there are two models available from our dealers...one with case number 581 and the other 117...it seems that the 117 case is more accurate...other than that i think they don't differentiate...maybe the crystal, one one case - 581 again - if i remember well the 2 crystals are not sapphire but 1 is mineral...there has been a lot of discussion between members on RWG regarding this 581/117 cases.....i think angus is capable to offer the 127 with some mods as fixed can pin and superlume (that isn't the same in quality when done by our modders...ziggy...vacuum)...you have to ask him for this model...
If I were you...i'd look for an already modded 127 from 2nd hand market or wait DSN to get another batch of his fiddys
