This is just a refresh for those who may have forgot about this problem...
Some of the pics have been taken one year ago from SSteel, some I've found on the web and modified later.
Recently I purchased a watch from a member of the cousin forum RWG.bz, knowing it had some problem and thinking that I could have fixed it, supposing it to be an Asian Eta clone.
Unfortunately, when I got it in my hands it turned out that it was not an Eta clone but something that looks similar but it's one of the most terrible movement I've happen to see.
The "infamous" Z2 clone-of-clone, also called "new breed high beat asian", also called PieceOfShit (POS) movement. Real code is "SB1HRZ2":
It was in this watch, sometimes misrepresented by the original TD: http://www.tswatchltd.com/15942-om15942-seamaster-pro-300m-black-ceramic-ss-a2836.html
Well guys, STAY AWAY from that movement. It is really as bad as it can be. The escapement works fine (it can keep good time), but the rest is a disaster, starting from the terrible finishing of it.
Just a quick refresh to see how you can spot it in the following pictures. Note that what I write about ETA is valid also for the real Asian ETA Clones like the Seagull ST21
1) the POS dial is kept in place by screws and not by hooks like in gen/asian ETA:
2) the click is very different and really as bad as it can be: on the POS is on the ratchet wheel, on the ETA is on crown wheel:
3) the autowind bridge is also different: on the POS all the reverse wheels are not kept in place by a lower bridge, while they are on ETA
The first 2 points are the most recognizable out of the movement.
Look carefully and you may spot some detail that will let you discover the POS signs, like in these examples:
Note that you can't just swap an asian ETA there because:
hour or minute (don't remember) hand will be loose on the ETA
date wheel is totally different and will not fit the ETA
Also note that there are NO spare parts for it (and being a POS it doesn't even deserve them...) and also simple parts like the stem are not replaceable with ETA ones.
