The Miyota 9015 used in replica watches isn't a clone it is a genuine Miyota movement made by Citizen ( they are cheap to buy in bulk ) . It is good reliable workhorse movement , i find they wind well , they have instant date change at 12am and keep much better time than the published specs . In fact i have a couple that are astoundingly accurate +- on a 2-3 day wear . The only problem is they have a UNI DIRECTIONAL rotor which is noisy . The movement is easily replaced or serviced .
The Asain2824 used in reps is again reliable easily serviced etc and doesn't have the noisy uni directional . However the date change is not instant ( or classed as gradual ) it will begin to change somewhere near 12 and flip on or around 12 . Although i have a genuine watch that begins to change at 11.30 and doesn't flip till 1ish .
THE BEST Pelagos is the V6F/ XF ( same factory TD's use both Monica's as reference ) it is classed as a SUPER REP on the NWBIG list ( the ZF is not ) . They have had both movements in . However the latest version of the V6F/XF (V4) has a Miyota 9015 decorated to look like a Tudor MT5612 . The V2,V3,V4 of the XF/V6F are all classed as Super Reps . There are no differences cosmetically , the differences are to the movement and decoration of it . You may be able to find one knocking about with a TD or on M2M with the clone ETA if you prefer to the Miyota . Members reckon they have solved the noisy Miyota rotor with a little mobius oil to the bearings . Not sure if that works myself .
A great choice of rep to get back into the hobby .
