Rudis Sylva – RS23 Harmonious Oscillator - Unique Limited Edition 2023

"An invention as important as the Breguet Tourbillon"
"Better than a Tourbillon"
"The Tourbillon reference"

These are just some of the comments from master watchmakers and industry journalists since the Harmonious Oscillator was created!

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.

Hailing from the Jura Arc, the brand unveiled its invention at Baselworld in 2009. Watch enthusiasts rushed to discover this toothed-balance movement, which is based on technology that goes against all established watchmaking theories. 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.

RS 23, the natural next step for the Harmonious Oscillator

Today, Rudis Sylva is launching a simplified version of the Harmonious Oscillator which is, nonetheless, equally effective in terms of combating gravity.

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

This simpler execution with two connected balances 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 which needs 60 seconds to compensate for the effects of gravity.

Rudis Sylva, a name with Latin roots

Rudis Sylva, a name with Latin roots Rudis from Ruedin Jean, the pioneer born in Franches-Montagnes around 1400, and Sylva, the forest.

Rudis Sylva is the old name for the Swiss village of Les Bois in the Franches-Montagnes district, 12 km from La Chaux-de-Fonds. In 1900, some 600 of its 1450 inhabitants were watchmakers! The first recorded watchmakers in the village date to 1750. The most well-known of these are the Clémence and Baume families, who opened stores in London to sell their products, which included timepieces with chimes. The Rudis Sylvains – as inhabitants of the village Les Bois were known – passed on their watchmaking expertise throughout the Jura area over many centuries.

Exceptional finishes

The Harmonious Oscillator is a patented movement developed solely by the brand. Whilst the movements are, first and foremost, technical by nature, they are also all decorated by hand, showcasing the skills practised by the craftspeople of the Jura for centuries. When the brand was created, it was the regional expertise that was showcased rather than that of any specific watchmaker.
