Description

The DuRoWe caliber 74202 is a common 11 12 ligne handwinding movement with 17 jewels, which is constructed in a familiar way. It is a direct relative of the 74102 and differs only by the size of the main plate.

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.
