Re: Sinn U1 and U2 $138 in 21j auto movement
Actually the ETA version comes in 3 variations : ETA clone, used Swiss and new Swiss. It seems only Angus officially proposes them all. That means if you buy from Josh and Trusty, you'll get the used ETA by default (you can't get the new one for this price, and it can't be the clone, as it's not advertized).
Honestly, the 2813 (Miyota 8215) seems to be a bargain if the rest is strictly the same as the ETA version.
I'm a bit surprised, usually the rep manufacturers "downgrade" the lower end versions (mineral instead of sapphire, no AR, no serial and these things...)
That's where I'm not sure the Quartz version will have the "high end" details/finishing. But I can be wrong. There are (few) models which are the exact counterpart of the high end versions + a quartz engine (some Aquaracer or Timewalker, which I owne(ed))
