Kienzle 060a1

Description

The large caliber 060a1 with a diameter of 12 lignes belongs to the late area of Kienzle’s movement construction. It was produced in the early seventies.

Construction-wise it resembles very much the (smaller) caliber 059 and an indirectly driven center second.

On the dial side, you find the familiar rocking bar winding mechanism. The unusual large and slim three-leg balance is beared in a pointed staff without shock protection. She controls with movement with a pin lever escapement.

So far this movement is nothing really special, but there’s one detail, which makes it standing out of the mass of simple pin lever movements: The pins aren’t made of metal but of synthetic rubies. The advantage of this patented technology is, that she is cheap but also much more reliable and precise.

Another detail at the end: In these movement, seven jewels are used. Interestingly, they are all integrated into the visible top plate, which gives this movement a “better” appearance.
