Date Change Starts at 10:30 or 11:45? / Coming Soon . . .
In Response To: Re: Found: Lowest Serial Number Yet for Carrera 1153 ()

Caliber 11 used the "jumping" / quicker change, which started at 11:45 PM. This required too much power, so the date change was slowed on the Caliber 11-I, so that the date change started at around 10:30 (and was more gradual) See the longer, more gradual "ramp", for the Cal 11-I and Cal 12, shown below.

Coming soon, a webpage that will cover all this . . . Cal 11 / 11-I / 12 / 15!!
