The thread Ginseng108 provide is an excellent source to learn about the various movements/calibres. In addition to this thread, below is an article providing a narrative on the ETA 2824-2, ETA 2892, and the Valjoux calibres. Also, below you will find another great website detailing the various movement calibres. In particular, the ETA 2893-2 calibre, which compliments the material covered by CaliberCorner's on the ETA 2893-2.Just pulled the trigger on a Stenhart. Noted that the seller included this info. Can anyone clue me in as to the differences between the three ETA models here?
