Testing Pocket Watches Timing

Been long time since I had these watches run and timing test.
This time I will let these old folks run, and the contestants are 1960's Omega Geneve, 1925 Longines and oldest folk early 1910s Roskopf Systeme. Opps, that Minerva stopwatch is only a sidekick ;)
So it begin..

After 12 hours, this is the result..

As expected, Omega handsomely outtrown the rest. I just noticed, Longines needs some adjustment on the hour hand, and probably some servicing too. Roskofp, definitely need some servicing and timing adjustment.

But all in all, these folks still ticking!!
