    Hi All,

    Here's my opinion on DG and clone ETA movements, yes I have a bias, but it is based on engineering principles and hands on machining practices.

    A mechanical movement relies heavily on "surface finish", and manufacturing tolerances, I'm not talking here about pearlage or fancy gold plated decorative finishes. I'm talking about the actual pinion finishes, gear tooth finishes, I'm now talking micro-mechanics. The friction generated between two or more mating surfaces is directly proportional to the surface finish.

    In simple engineering terms the rougher the surface finish the more friction is generated, the more friction generated the more the wear there is on that component, which inevitably means less reliability. yes you can introduce oil which does reduce friction to a certain extent, but we all know the less oil the better, yeah?.

    In my experience, most, if not all Asian movements simply haven't mastered the art of manufacturing a movement with excellent surface finish and tolerance. An example is the Sellita clone, it is supposedly the most gen like eta movement and yet all eta parts do not fit, I wonder why?, when it is Swiss ?.

    You can argue that ETA is not the benchmark for movements, but unfortunately IMO apart from Omega it is.

    Yes the Chinese are getting there but not for a while yet, this is substantiated by the fact that the clones are developing, you will all know that the early clones were rubbish, two generations up and were getting closer, but we're still not there yet.

    I do appreciate there are some very dodgey movements about and I do take on board the general census of this post, however, if you can get a totally gen ete then my advice is buy it, it will last you a lifetime.

    Hence the relative cheap prices for Chinese movements. You pay peanuts you get monkeys. But these have come a long way.

    I have to disagree with some of the opinion shown here...

    Essentially the 'swiss movements' are not worth the premium over the clone movements as I have done teardowns on both and came to conclusions in those arcitcles....

    My thoughts are that the clone movements whilst not quite up to 'eta' standards are still extremely good value. They can be repaired relatively easily and most eta parts fit it. It can also be swapped out for a new swiss movement at a later time. I also think that the levels of fit/finish on the Asian clones is not as good as ETA yet but that does not mean to say they should be avoided.

    Regarding ETA/Sellita - I have no real issue with Sellita, I think they are decent movements and nearly as good as the equivalent ETA. I can't say for sure if they are as good at this point. I've swapped certain ETA/Sellita parts with no issues.

    ETA is essentially the 'benchmark' we judge all movements against; whether this is a good thing or not is open to debate, however the fact remains it's what happens

    Hi Smidsy, I fully appreciate your point of view. The clones do represent reasonable value for money and I do agree that they are getting better.

    One of our biggest problem at the moment is spares !. If they were available from a reliable source without relying on ETA they would represent even better value for money. As far as I am aware there are no suppliers of clone movement parts?.

    Perhaps we should see if one of our senior members could take this up for us with the manufacturers?. I'm sure it would be really handy for all members?.

    Because the thread is 4 years old and they might not be maintained by the OP.

    I'm afraid that Imageshack has removed all 'old' images when it was redesigned.... Lots of my review threads have been similarly affected so unfortunately there's not much I can do....

    I'm not sure I have a copy of the original images even but if I do I'll attempt to fix when I have a day free.
