Some relativistic storage rings can be operated in single partcle mode.
And it is possible, easy in fact,
to detect each passing of the particle.
So yo can just read your (electronic) stopwatch
to measure the once-round the ring time,

That's not what I'm talking about, and I'm saddened that Paul B. Andersen,
who is not an idiot, who is not a thug, who is not a bandit, does not do
the effort to understand what I have been saying and why I have been
saying it for 40 years.
It is obvious that if I place a proton in a circular ring, I will have to
calculate very precisely when the proton passes, and that this calculation
can only be done by the laboratory watches.
 
But if I could put a watch on the proton, and I asked it how long it takes
to complete one revolution, the proton would tell me "much, much less time
than the lab clocks say."
This is called duration dilation.

Why don't you ever read a book, or use standard terminology.
What you are talking about is called the proper velocity,
aka the celerity.

George Gamow was already making jokes about it
in Mr. Tompkins in Wonderland, (1940)
