Random serial numbers- for or against, and why?

[toolr]

I think anyone buying a new watch from an AD that says it doesn't matter the serial number is being somewhat disingenuous. Given two identical watches sitting in the display case, one a F serial and one a V serial I think all but a few who do not know watches or do not like the rehaut engraving would opt for the V serial. The lubricants are fresher and the watch would normally be less case worn and handled.
