HB 115 MS


The HB caliber 115 MS originates from Pforzheim, Germany and is a typical mid class german wristwatch movement.

It contains 17 jewels, with two of them used as cap jewels on the dial side, which is pretty unusual. The screw balance runs in two shock protection systems, maybe Monorex, and there is a long regulator arm with a nice dial on the balance cock.

The movement, which uses a directly driven center second hand, is built in two levels, which makes it appear rather high.
