28000 bph how to tell?

There's still a detectable beat at 28800, very small but visible close up. From about a foot or so back, it will look smooth. A 21600 will have a more obvious beat, and from 1 foot away you can still see it. -_-

There's a definite audible difference between a 28800 and 21600, but I don't know how to describe that unless you have a watch to compare. I have a couple ETA 2836-2s, and there's an obvious difference between those and one Asian 21J 21600 I have. Now I can compare by sound. 28800 is much more enjoyable. :p

But really you'd have to open it up and compare the movement to images to know exactly what movement you have.

Thanks for all the information.

I loved the one second photo thing..really cool...wow...

The watch i got is the hbb full ceramic..lucky for me it has a glass back, and you can see it has no regulator. And lucky for me there are many pictures on this site to compare. It definately has no regulator (a clear tale sign on the hbb big bang it is a fake).

So i am assuming it is a 28000 bph..
