Job Number 260012

I replaced each gear in the winding/setting mechanism one at a time to try to get at a specific rough spot in clockwise setting. I turns out that the minute hand squeezes the cannon pinion enough that it causes clockwise setting issue. I can't loosen the minute hand or it will falloff. I can't loosen the cannon pinion any further or the hands will slip and not move at all as the watch runs. I will have to work very carefully to alter where and how the cannon pinion grips along the center wheel shaft.


Just to make things extra complicated, there is barely enough space on these to allow the hands to pass each other, and to pass over the second hand, without colliding. The special issue with these Elgins though is that, as in the case with the keyless works, other manufacturing tolerances are not high enough to make these adjustments go smoothly. For example, the minute hand finds much less clearance above the hour hand on this watch when the hands are both down near 7:00. 

Elgin number 4592421 is a grade 118, 6 size, 11 jewel, made about 1892.
