The 44 mm watch was announced in limited titanium and 18k pink-gold editions. Monochrome Watches reported 2023 launch prices of CHF 80,000 and CHF 90,000 respectively; those historical prices do not establish a current offer or the watch’s present availability.
What is the Rudis Sylva RS 23?
The RS 23 is a wristwatch model; the Harmonious Oscillator is the movement concept at its centre. Rudis Sylva’s official RS 23 page lists a 44 mm case, 12.9 mm height and the patented oscillator (patent no. 700747). Its product images show multiple case and dial treatments. The model is offered in titanium or rose gold, with the launch report specifying 18k pink gold for that edition.
Monochrome Watches’ 6 February 2023 launch report describes a hand-wound movement, around 70 hours of power reserve, 30 m water resistance, a domed sapphire crystal and an alligator strap with a matching pin buckle. Rudis Sylva’s model page is the source for the stated dimensions; the launch report supplies the additional launch-era details.
How does the Harmonious Oscillator work?
Rudis Sylva describes the system as “two mechanically interlinked balances driven by a single escapement” on its Technology page. The manufacturer says the balances’ springs are arranged symmetrically and their energy opposed, producing instantaneous average correction when the watch is in a vertical position. That is the maker’s explanation and performance claim; the cited material does not provide independent comparative accuracy testing of the RS 23.

The technology page describes a 3 Hz rate (21,600 vibrations per hour), around 70 hours of power reserve and a 60-second rotation for the broader oscillator technology’s cage. That rotating-cage description should not be mistaken for the RS 23’s layout: Monochrome’s launch report says the RS 23 oscillator is not housed in a rotating carriage. Rudis Sylva calls the system “unique worldwide” on its model page; this is the manufacturer’s characterization, not an independently established market comparison.
