The DuRoWe caliber 7410/2 is a common 10 1/2 ligne handwinding movement with 17 jewels, which is constructed in a familiar way.
It uses a three-leg balance, which is beared in two Rufa-Anti-Shock protection systems and whose hairspring is connected to a moveable stud and adjusted by a long direct regulation arm.
The center second is directly driven and the minute wheel is in the center.
On the dial side, you see the yoke winding system.
