The most recent rebuild a few months ago, stateside, by a long recognized repairer.
The overall mileage was set to zero about 40 years ago.
The trip odometer has not been reset; but now want to see how to reset it to zero.
Tried different ways to spin the stem -- including pushing it in and pulling it out -- to turn counter and anti-clockwise, until one way of spinning finally got the wheels to move.
After spinning the stem for 30 minutes, the odometer went from 926.8 to 960.2 -- still a long way to get to "000.0".
The spinning stem moves the tenths (red) wheel to engage the "ones" wheel to engage the "ten" wheel to engage..... with each flip of the wheel taking many spins.
Thought I would eventually get to engage the last wheel, but ran out of time and patience, plus worry that that I might be wearing out some cogs.
Occurred to me that this exercise should not be so time consuming and cumbersome, since it is merely to reset a "trip". Did research, and do not see any other Online advice about this topic, nor is there anything about this in the Jaeger brochures, manuals and notes. Even the 12 page Treatise by Carl Cederstrand: "Jaeger Chronometric Instruments TA, TB, TC, and Early TD"(1997) does not relate to this question.
Can anyone tell me whether there is something wrong inside the speedometer, or that I am doing something wrong, or that I need to send this back for more repairs?
I know that if I go inside, there are mechanisms that are spring loaded that might fly out..... so hesitate to take apart further by myself.

Somehow, must have missed the action when first tried to pull down and turn clockwise -- which works!!
I did find the part about spinning the wheels that increases the mileage but got trapped into doing that.
BTW-- found that the bezel openings, for the transparencies that let in panel lighting, had been rotated 90 degrees -- so that NO light came into the face of the dial. This fault was added to the built-in difficulty with getting light to the panel instruments -- which is another exercise.
