ETA: ETA SA swiss Watch Manufacturer
7750: Valjoux 7750
Japanese movement
Generally speaking, the quality among these three kind of movement is like this:
ETA > 7750 > Japanese.
That’s why Japanese movements are 10-30% of the price of a swiss movement.
Most watch companies are using the ETA or Valjoux 7750 to make their watches, except the rolex, as rolex make their own movements.
So almost all the other watch company just use the same watch movement, the only differences are the decoration, they just modify them with extra functions, like jewels, etc.
The movement is where the watch was made, the movement is generally a sign of the quality of the watch. jap movements along with chinese movements are the cheapest.
If you get a swiss movement, they are generally regarded as the best.
The movement is basically the internal workings of the watch, the better the quality the longer it will last and the smoother the hands go round.
