While ETA 2824 and, in the smaller capacity of Soprod, A-10 has won the third party and non production of the Swiss automatic movement as a matter of fact, the Asian team is catching up. Although previous generations of Seiko and citizen Miyota movement may not have direct competition, like 7s26 8215 strong, but not very accurate or select examples (non hackers and hand winding), the gap is much narrower than the current generation.
With the 4rxx and MIYOTA 6rxx 9015 we see the possibility of more sophisticated motion features of the hackers and the hand wound as well as the more successful precision adjustment (accuracy depends on many conditions). All indications are that the reliability should be good or better service should be roughly the same as the cost range of the entry-level Swiss, in many cases, cheaper components. From a functional and reliability point of view, I think 6rxx and 9015 can be comparable to the standard grade ETA 2824, but there are subtle differences in the use of. For example, 9015, there is a note that the rotor noise. That is, when you have a wave of your arms to check, you can often hear the case of the rotor rotating. You need to have your ears very close to hear the ETA rotor. I only mention this, they are not the same, more like a different actor to play the same role.
Swatch limiting the supply of ETA movement non swatch partners, I think proliferation Seiko and citizen Miyota movement will expand, because the design has been proved enough and have a role, to fill the 28xx caliber. A few years ago, you can with a ETA movement in ~ $700 for micro brand divers. Today the prices will push (if not more than 1000 US dollars. Many small brands have switched to NH or Miyota motion not only due to the cost and supply, but also because of the new generation of proof is significantly better than 7sxx and 8215.
It seems to me that the time is beneficial to them, and to solve the reliability caused by the characteristics of timely fill middleman ETA provide predatory pricing. I have a 9015s couple watches, in addition to the rotor noise, the movement seems to be a very successful substitute 2824.
