Obviously there are many other ways to distinguish authentic from fake but my question is, does the Rolex movement actually have a 1/4 sweep, meaning 4 quick movements per second or is it actually more like an 1/8th sweep or 8 movements per second?
I've been watching my second hand for a few minutes and I find it hard to believe that it is moving less then 8 times each second
Thoughts?

Most all mechanical watches today including Rolex beat at 28800BPH 8 ticks a second, some high beat movements beat at 36000BPH 10 ticks a second.Older Rolex movements like the bubble back and say cal 1560 18000BPH while the cal 1570 was 19800BPH
