A simplified version of the Rudis Sylva’s Harmonious Oscillator.
The name Rudis Sylva comes from the previous name of Les Bois, the small Swiss Jura village where this niche independent brand is established. It comes from Jean Ruedin and Sylva, the Latin word for forest. In the 14th century, Jean Ruedin was one of the first settlers in the region known today as the Franches Montagnes because of a tax exemption for the inhabitants of this forested area. What sets Rudis Sylva apart is its Harmonious Oscillator. The brand now introduces the RS23, featuring a simpler version of this unique oscillator, now without a rotating carriage, which is also (relatively speaking) more attainable.
Truly unique in its kind, the Rudis Sylva Harmonious Oscillator comprises two balance wheels. As a rule, watchmakers avoid any potential stress on a balance wheel for it to breathe freely. In this case, the two balances are toothed and thus mechanically interlinked. The first balance is driven by the escapement, and in turn, it drives the second balance. The balance wheels, therefore, rotate in opposite directions with the same amplitude, while each hairspring breathes in an opposite way. The underlying idea is that these constantly opposed balances ensure immediate mutual correction of the potential negative effects of gravity. A stop-second mechanism allows for precise settings. It beats at a frequency of 3Hz and it boasts a 70h power reserve.
Unlike previous versions of the Rudis Sylva Harmonious Oscillator, the regulator is not placed in a rotating carriage. This has allowed building the movement architecture in a symmetrical way with twin barrels creating a counterpoint to the balance wheels. And instead of an off-centred hour and minute display, we have a central indication of the hours, minutes and seconds. Identical to previous Rudis Sylva watches, the movement is nicely finished. The main plate and bridges are sandblasted and hand-chamfered. The oscillator bridge is flinqué.
This hand-wound movement is housed in a titanium or pink gold case (as seen in this article). If it is still 44mm, the smaller opening and the presence of an internal flange make the Harmonious Oscillator RS 23 look smaller than the previous Rudis Sylva watches. It is also slightly thinner at 12.9mm. The design is built to maximize the spectacle of the movement inside, with no bezel and a domed sapphire crystal allowing you to enjoy the three-dimensional movement from every angle.
The Rudis Sylva Harmonious Oscillator RS 23 is released in two limited editions of 8 pieces in titanium and 8 pieces in pink gold. It is presented on an alligator leather strap with a pin buckle matching the case material. The price is set at CHF 80,000 in titanium and CHF 90,000 in 18k pink gold.
