Hi Tyler,
I'm not a technical person so I'm juz expressing my view. Of course, I may be wrong.
Somewhere in this forum, there are some threads that share on the accuracy of the co-axial movement ( think it's related to Aqua Terra ).
From my knowing, the co-axial movements are running at a slower rate of 25,200 BPH compared to the traditional movements of 28,800 BPH. If I understand it correctly, shouldnt a movement running at higher BPH be more accurate? Even if you argue that they are certified chronometer by COSC that has an accuracy of -4/+6 secs per day, then where does Grand Seiko stands which is running at -2/+5 secs per day?
In addition, a slower beating movement also means that its second hand is ticking less smoothly. If you work it out, it's ticking 1 time less per sec. So why is it that co-axial can't be adjusted to run at 28,800BPH? Is it becos to accomodate their claim that all co-axials can withstand wear and tear over a longer interval or is it becos the movement simply can live up to the bar?
I hope your "test" will shed some light for me...
Happy Weekend!
