pjsayer 1 Posted June 29, 2011 Just a quick one from a newb... Does anybody have any mid- to long-term experience with the high beat 21J DG4813 movement? I've bought two subs and a PO 42mm with this calibre and was just wondering how accurate and reliable they are? I'm guessing it should be relatively cheap and straightforward to change if one breaks down but just wanted to know if you guys thought it would be worth upgrading to an ETA clone?
