Позволю процитировать уважаемого Андрея Бабанина :2824 и 6R15 одного поля ягоды - без доработок реальные конкуренты.
Смотрим далее:
Beat or speed: The 2824 runs at 28,800 while the 6R15 runs at 21,600. In theory the faster movement is supposed to be better. For most mortals the noticable difference will be in the seconds hand. On the ETA movement it will appear somewhat smoother than the Seiko movement.
Power reserve: The 2824 is about 42 hours while the Seiko is significantly higher at 50. The Seiko accomplishes this very useful feat by using a composite spring that I understand is longer.
Hacking: Both movements provide for hacking or stopping the seconds hand when setting the time.
Handwinding: Both movements provide for handwinding. This feature is probably overvalued for two reasons. Both movements have efficient winding mechanisms that with a few swirls of the rotor will start the movement and subsequent wearing will keep the movement running. Continual handwinding to full power will introduce unneeded crown and winding mechanism wear. The ball bearing supported rotor was designed to minimize crown winding so just use it!
Maker reputation: Both Seiko and ETA owner Swatch have established reputations for delivering quality products and backing them up. Reputations simply don't get much better.
Parts availability: While most watch movements will not need a replacement part for decades some will. The ETA 2824 has been around for a long time and is used by numerous companies. Thus a supply of new and second hand parts is pretty well assured for the forseeable future. The 6R15 is relatively new and so parts or complete movements can be sourced. There is not a ready inventory of used scavanger movements although some components from the closely related 7S26 ans 7S36 may be interchangeable. Whether the 6R15 will remain in production long enough for a deep supply of donor movements to develop is open to question. Other promising movements like the 4S15 were dropped after about 6 years. I suspect that the composite 6R15 spring will be very durable. Whether a complete new one can be easily sourced 30 years from now will be at least open to question.
Accuracy: Either movement has the potential to be either very or just passably accurate. Accuracy is really dependent on the time taken during and after assembly.
Which to buy: Either movement will deliver decades of good performance if maintained. I would base a purchase first on how the watch looks and fits and only secondarily on the movement it uses. Most 6R15 powered watches are unfortunately overpriced in my opinion because of an unfavorable exchange rate and an aggressive repricing of watches by Seiko. 2824 and 2892 powered watches can be found at times well under $500.00.

Сообщение от Baggio
Когда механизмы нормально отрегулированы и в остальном с ними все в порядке и там и там точность одинаково хорошая, лучше обоих этих допусков.

А ЕТА регулировке не поддается? Или может у владельцев швиссов просто нужды нет в корректировке конвейерных настроек?
