ETA Calibres - a quick FAQ

Recommended Posts

greg_r

This is a quick (and somewhat incomplete) list of ETA calibres. This is by no means intended to be definitive, but hopefully will help answer a few of the more common questions.

 

Info has been compiled from several sources including ofrei and eta.ch - if a movement isn't included here (such as the 7753) it's because I didn't find it in the places I looked ;)

The Swiss ETA 2836 (and variants) are very hard to tell from the clone version, and few dealers can be relied upon to supply the gen ETA vs. the clone (because they can't tell the difference either). As a general rule, you will tend to receive either the Asian clone version or, if gen ETA, a used or refurbished movement. A couple of our dealers CAN be relied upon to supply the real thing - so if that's what you want ask us and we'll point you in the right direction. However, personally I'd stick to the Asian clone as it's pretty much just as good.

I was about to pull the trigger on a vintage sub with an ETA 2842 movement. There are other upgrades that somewhat justify the 750 price tag, but the info here on the 2842 indicate to me anyway that particular movement is not really a high quality movement. Am I understanding that correctly? If it's available in an $85 Swatch, then I would assume there's nothing there that would justify paying such a high price. Am I taking that correctly? Would I be just as well of with an Asian clone, or a well regulated 2813 or 4813? Or is the 2842 a very reliable engine?

It's a good movement, however not worth the cash on upgrade.

 

IMO, buy a cheap version & source the 2842 separately - if you intend to mod it of course.
