How long is the life of Omega 1 120 movement?

1 120 is about 1985. When Omega modified Cal.2892, it became a special movement below it. And they all passed the Swiss Observatory certification (C.O.S.C), so each one is an observatory movement. The original 2 1 ruby has been increased to 23. Two of them are placed on the upper and lower shafts of the spring wheel to improve the smoothness. The part of the automatic disk is thickened, and the balls are smaller, so the noise generated is naturally smaller, and two positioning pins for fixing are added. And the automatic transmission wheel is designed to be detached separately, which is convenient for free disassembly and maintenance. Omega Cal. 1 120 is rhodium-plated, the splint and automatic disk are Geneva corrugated, and the details are polished with fish scales, which is obviously better than ETA Cal.2892, thus it can be proved that the quality and function of Cal. 1 120 are absolutely not inferior to the movement used in high-priced meters.

The service life of mechanical watches is generally more than ten years. However, the life of mechanical watches is generally shorter than that of quartz watches, which is determined by the internal operation structure of mechanical watches and quartz watches.
