Swiss movement ETA watches can be said to be a huge family, there are a wide variety of models of all sizes, producing a very long history in the 70s of the last century has been formed on the system and scale. In fact, we are now common to watch the movement, at which time there have been. At that time, the Swiss watch industry there are a lot of other movement manufacturers, age 70-80 in the last century, imports of watches from Switzerland can be seen. Although the time for essential imports which are the general form of the brand, but are basically the hands of string, movement manufacturers in addition to ETA, there are relatively well-known AS, FHF, ST, F and so on, then Switzerland is said to have more than 600 home watch manufacturer, somewhat well-known watch manufacturers, many of whom are self-produced movement, known as “the all-around plant”, the output is also a great, such as the well-known there ENICAR., ROAMER, but basically to the mid-80’s movement do not , and have become assembly plant. Apart from the impact of quartz watches, the production cost is too large, the reasons for lack of competitiveness is, in fact, the most important factor, I would like to be not as good as ETA movements or design so reasonable, the accuracy of travel time reliability as ETA, and now the machine Core (also including the quartz watch movement) is basically dominated the ETA.

ETA mechanical watch movement characteristics:

1, eccentric drive design, there is no center round the splint, so that movement can be done relatively thin.

2, large diameter round bar boxes and large diameter balance wheel, the length of travel time in general more than 40-50 hours in between the relatively large output torque spring, balance wheel moment of inertia than a larger swing is relatively high, the stability of travel time, anti – interfere good.

3, relatively easy to dismantle and assemble, repair time can even be in the washing machine table to “whole” cleansing. (Only to be demolished and the balance wheel round box, not the demolition drive round)

4, parts common good interchangeability.

5, would easily give rise to all types of functions and additional.

6, large output, low cost, relatively cheap.

The same ETA movement, different grades, one of OMEGA or TUDOR movement ETA2892-2 and other brands of watches, the general movement from their appearance alone will be able to clear distinction.

1, first of all, that is, the modified splint grinding. For example, there are scale patterns, so very beautiful, also very bright, even the screws are polished; splint there are still many lettering and logos can be said to be beautiful works of art.

2, Second, key components, materials technology are also different. Better brand watches will table their own brand names carved on the steep bank on the automated, low-block is used at most watch paint printed on the automatic Tuo, or simply do not play marking; lowest block is the ETA movement is in the Far East regional assembly, the splint is not gold-plated, with a triangular spring earthquake, such as the 2688 and 2846 movement.
