I own(ed) both of these movements...
the cheap asian PR movement was great when I had it and it still runs in the same way on my friends wrist...as sssurfer said the asian movement gets fully wounded in a couple of hours when worn...for a little over 100$ this is one of best reps available (090,222,124,027/028 asians)...and it keeps time really accurately
lately I've been having some problems with the 2892, something strange is happening...well I had probl from the very first beginning when I got the watch from EL...the mvt came broken...and when I got it back from the watcsmith again it didn't function properly...now the PR isn't good at all, once it is fully wound it stops randomly when worn, the PR pointer won't go furter down than 20-30 hrs...it is/was my mistake I haven't brought it back to the watchsmith immediately when I noticed it but I wanted so badly to wear it (waited for more than 3 months to be repaired in the first place)...next saturday is going back to the watchsmith to see where is the probl...hopefully nothing really bad...
as I have said in another post, I wonder why the rep factories haven't done the asian PR pams (27/28) in a more accurate way...I bet the sales would be really great...cause the movements proved to be super reliable...now the only thing is to correct the dials,crowns,CG,and cases...and we would forget the ETA's really quickly!
