Mosler Replacement Movement: Built using the 104 series gear train, this movement will replace most Mosler movements in use today. The screw mounting pattern is a precise match to Mosler. The drawback is that these movements wind counter-clockwise and not like the original Mosler movements that wound clock-wise. There was no practical manner open to us in the desIgnition of the movement to accommodate clock-wise winding. Other features of this movement include: Reset, 168 hour possible locking hours, 17-4PH unbreakable mainspring, and Adjustable indicator.
