What's the difference between omega 1 120 and 1 164? Now I want to buy one of these two specials. If there is no big difference, I will buy 1 120.

Omega 1 120 movement is polished with ETA2892 as the substrate, and the original 2 1 ruby is increased to 23. The additional two are placed on the upper and lower shafts of the spring wheel to improve the smoothness. Automatic disk partial thickening. Add two locating pins for fixing. And the automatic transmission wheel is designed to be detached separately, which is convenient for free disassembly and maintenance. Omega 1 120 movement is rhodium-plated, the splint and automatic disc are Geneva corrugated, and the details are polished with fish scales, which is obviously better than ETA 2892. And they are all certified by the Swiss Observatory.

Omega 1 164 movement is polished with ETA7750 as the substrate, and the six-needle chronograph automatically winds the observatory movement. The automatic winding system is strengthened and the winding reserve is increased. The movement has stable performance.

1 120 movement and 1 164 movement are both low-end movements in the Omega product line, but the brands of Omega are available and the quality is still quite good. If there is no great requirement for the timing function, just select 1 120.
