seem like a easy qns, but I am not able to offer a short ans. what is the definition of low end? movement not found in Rolex/JLC/Zenith?

quartz Tissot - not seen movement grades on these quartz movement. if there is no movement grades on quartz, U may find a Omega or tag running on the same quartz Tissot. so it it low end movement?

mechanical/auto Tissot - watches on ETA 7750 are always on elabore grade or better and U find in many more expensive watches on the same grade.
those on 2824 uses Standard grade. is that low end?

remember pay peanuts get peanuts. Tissot with so much marketing, U do know who is paying for that right?

a good majority of swiss legend mech watches uses Chinese Seagull movement, thing is 51% of the movement is make and assembled in Switzerland which make it swiss made!

the quartz ones are generally running on Ronda.
