The so-called Omega's most advanced chronograph movement is the 9-series chronograph movement used by both. The 9300 chronograph movement used by the automatic 57 is a new generation of automatic chronograph movement developed by Omega in 2011 based on Omega's exclusive coaxial escapement. It uses a silicon hairspring, adopts a vertical clutch and column wheel chronograph structure, and has a unique binocular chronograph dial, which integrates the 12-hour chronograph and 60-minute chronograph into the 3-point chronograph dial. In terms of aesthetics, it is decorated with arabesque Geneva stripes and black-plated screws. The movement used by the manual 57 is called 9906, which is the manual version of the 9900 movement without the automatic rotor. The 9900 caliber is an upgraded version of the 9300 caliber, which meets the high-level Master Chronometer standard. The anti-magnetic field reaches 15,000 gauss, and the travel time error is also increased to 0 to 5 seconds per day. The biggest advantage of 9906 after removing the automatic rotor is that the watch becomes thinner. Although the effect is not particularly obvious, it is not harmful to be thinner. In addition, since the power storage of both watches is 60 hours, there is no need to worry about choosing automatic and manual movements, because there is no obvious difference in performance between the two movements.High quality Chinese replica Omega Speedmaster watches online.
In addition to Omega's latest movement technology, the Speedmaster 57 is another worth buying point is that it is infinitely close to the appearance of the original Speedmaster. The Speedmaster 57 is named after 1957, the birth year of the first Speedmaster in history. In addition, two professional series, the Ironmaster and the Seamaster, were born together with it. They are the veritable three brothers of land, sea and air. The appearance of the original Speedmaster has three very obvious features, namely the broadsword hands; the crown and chronograph buttons have no shoulder guards, straight lugs and no twisted polished surfaces. Speedmaster 57 not only fully inherits these three features, but also its yellowed hour markers, luminous coating, dial text and box-shaped mirror, and the use of sandwich dials enhances the sense of age of this watch. Compared with the automatic 57, the biggest difference of the new manual 57 is that the graininess of the dial is more obvious, which makes the whole watch look more textured. In addition, the two 57 bracelets not only inherit the three-section shape of the original Speedmaster, but also have belts with different color dials to choose from.Best China
