ANDREAS STREHLER

Trans-axial Remontoir Tourbillon

In his quest for perfection, Andreas Strehler has designed, constructed and built a movement where internal influences on the already pretty linear power supply from the epicyclically limited twin mainspring barrels is filtered through a Remontoir d’égalité and transferred to a Tourbillon escapement mounted on the same axis to eliminate the influence of gravity on the escapement. The Trans-axial Remontoir Tourbillon escapement is hand wound, using Andreas Strehler’s own true conical gear wheels. To show the power left in the two mainspring barrels, the movement has a power reserve indication using an extremely small differential gear, another speciality of Andreas Strehler. The energy supplied from the twin mainspring barrels through the gear train is accumulated in a spring, acting on a satellite arm held in position by the star wheel (the satellite). One tooth of this star wheel is resting on the palettestone of the palette arm. This palette arm constantly moves ahead. Every second, the palette arm releases the star wheel. The star wheel turns by one tooth and the satellite arm jumps ahead by 6°. The satellite wheel then rests again against the palette-stone and the cycle starts anew.
