Usually just contact mechanical Omega Seamaster 300, the earliest known or used to the movement of nothing more than ETA 2824-2 and 7 s26 seiko, ETA 2824-2 which is not only sOmega Seamaster 300, high accuracy, also has the function of hand chain, although so prices higher than Japan movement, but in terms of various aspects, is still a new choice to get started. Same with ETA ETA 7750 as a 2892 – A2, ETA is one of the triple gem (another 6497, 6498 series also has a catch-up momentum in recent years), but the price is low many, so many fake Omega Seamaster 300 and the so-called Taiwan, Hong Kong tabulation, also adopts this movement, too the result of the flood, many people just hear ETA 2824-2 is counterproductive, and ignored his good nature.
ETA basic data for 2824-2: the diameter of 25.60 mm and 4.60 mm thickness, lowest power reserve 38 hours (but varies depending on the individual situation), 25 rubies, vibration frequency of 28.800 times per hour, the bidirectional automatic chain.
ETA time, published 2824-2 from the prototype has been more than half a century, and derived by the Eterna and ETA movement type is the worst case load, the family in appearance, vibration frequency and the balance wheel type is slightly difference, but the use of transmission gear train and two-way chain system, didn’t do too much of a change. In the 80 s to the ETA 2824-2 series of production, there are many different kinds, including ETA ETA 2804-2801-2, 2 (with date) is taking chain structure of the hand chain on two-way automatic version, but still have other functions of ETA 2824-2, diameter of the same thickness reduced to 3.35 mm, but the appearance is not beautiful, in addition levels and parts of polishing is also belongs to the low price, after all, and 7001 ETA can choose, so this kind of movement is not common. Is also one of the most common ETA 2836-2, this is the design of combined with the function of week, thickness increases to 5.05 mm, believe that can meet the demand of large people, can be in the basic of ORIS, TISSOT, MIDO project, to see it. Other derivative with additional timing module, and the world time zone module, but is also relatively low visibility.
Calls on common market ETA movement, 2824-2 red meat is not the basis of the modified machine core, but the color is the color of copper alloy, not rose gold, and the cost is in two thousand yuan, but with the plating on the processing of nickel, rhodium, and all kinds of corrugated polishing, and change level higher balance spring and torsion pendulum device, looks very bright, also can be easily through the observatory’s test standard. From the earliest ETA 2824-2 of the original design to the present, the appearance is slightly change, but the name on the two-way chain institutions did not change all the time, about the efficiency of the two-way and one-way chain, who is still inconclusive, but used in the author’s experience, the chain effect is very good, as long as the exercise is big, box spring are nearly full chain state. So the most obvious advantage is that accuracy is very sOmega Seamaster 300, the bit error can be reduced to a minimum.
ETA 2824-2 in addition movement is thick, also suiOmega Seamaster 300 for use in the activity, such as the Colt one hundred spirit, using the observatory ranks of ETA 2824-2, through the test of foreign professional magazine and accuracy are satisfactory. In addition emperor rudder three needle and activity, also USES ETA 2824-2, but change the trimming device and change Kif shock, only one tree, also on behalf of the emperor rudder Omega Seamaster 300 factory stick to it. And Amy’s originality series, can be make ETA 2824-2 machine, fu and calendar, the moon and other functions, and polished, has get rid of the traditional impression of cheap. And the rest of the players, also think the ETA to the top ranks of the 2824-2 and ETA, compared to 2892 – A2 is the same in each aspect, the performance of ETA 2824-2 is pretty good. But design itself is a large number of production, more or less in the parts and the details of the substrate processing, also can appear to let a person of weakness, but because of their price positioning, so ETA 2824-2 are mostly appear in low price Omega Seamaster 300es. So within a reasonable price, the use of ETA 2824-2 machine, I want to Omega Seamaster 300 also is very famous for not only geared to the criticism.
