Official description

This patented invention with two toothed balances immediately cancels out the effects of gravity when a watch is in the vertical position, unlike a conventional Tourbillon, which needs a whole minute to do so.

An examination of this revolutionary device reveals the subtlety of the system with two balance-springs which are set in opposition and deploy in turn.
The negative chronometric value of one spring balance is compensated for simultaneously by the positive value of the other spring balance, which totally cancels out the effect of the Earth's gravity on the precision of the watch.

The toothed, geared balances are fixed and no longer rotate once per minute in a 360-degree cage as in the "Tourbillon" version.

This execution also allows all chronometric anomalies caused by the Earth's gravitational pull to be cancelled out simultaneously, and therefore remains more precise than a conventional Tourbillon.

A Rudis Sylva watch merits a magnifying glass to reveal the magnificence of the guilloche work, engraving, bevelling in the inward corners, sunray or circular graining decoration and the other finishes that enhance the Harmonious Oscillator.
