Marc Brogsitter's impressive watches use unique movements built using the design ideas of the observatory watches from the 50's and 60's of the last century.  Marc Brogsitter's movements have tremendous balance wheels of 17.08mm diameter.  Turning at the leisurely tempo of 18000 beats/hour they are a real joy to watch.

Brogsitter has designed 2 movements, a tourbillon movement and a constant force escapement movement, both using this very large balance wheel.

The extravagant cases also take up stylistic elements from some high end watches of the 50's and 60's.
