depends on the dealer and the specific movement in question. Some movements are harder to get in ETA thus you might get a clone instead. If its a basic submariner then yeah no problem go for the ETA.. but if its a Panerai or a watch with a 7750 chronograph movement then, BEWARE. let us know the dealer and the exact watch, and we;ll let you know what to do, OR we'll recommend what dealer to use.
