H.F.Bauer B568


Hard to believe, but in the 1950s movements with cylinder escapement were still produced, such as the Bauer B 568 shown here. This movement was launched in the late 1940s and had a modern look, mainly because of its geometric gear train bridge.

With a nominal size of only 5 1/2 lignes it was one of the smalled cylinder movements available and was ideal for the very popular tiny rectangular ladies' watches of that time.

The execution is very well, all important bearings contain rubies, ten in total.

The Bauer B 568 uses the classical gear train with a directly driven center minute wheel, third wheel, seconds wheel and steel cylinder wheel. The latter one is beared under its own cock.

The three-leg anular balance is not yet shock protected. It beats with 18000 and can be adjusted (at least in theory, because these cylinder movements have daily deviations in the minute range) with a long regulator arm.

As escapement, a really outdated cylinder escapement was used.

The dial side looks pretty modern in color and shape, and it even shows the yoke winding system.

Why Bauer released a cylinter movement in the late 1940s, at a time, where these movements were already hopelessly outdated, is unknown.
