Das hat mir keine Ruhe gelassen, drum mal etwas gegoogled & Folgendes gefunden:
"These long markers represent the post office fees that were once charged when making telephone calls – calls were frequently charged in 3 minute intervals and thus by running the chronograph, it could quickly be seen if one had run into the next unit fee." Quelle

"Finally, on the minute counter, the elongated lines at the 3, 6, and 9-minute markers were used to monitor the length of phone calls at payphones because you would get three minutes of talk time before being cut off. That is unless you inserted more money for another three minutes of talking time." Quelle


...geht ja nicht an, dass da Strichlein auf dem Zifferblat sind von denen keiner genau weiss wofür sie sind
Again what learned! Interessant. Danke!
