RS 23 Harmonious Oscillator

Among the first watchmakers in the Franches-Montagnes region were Captain Girard, François-J. Froidevaux and J-B Mauvais. In 1769, they had set up a small factory at La Planche, a farm in the village of Les Bois (previously named Rudis Sylva), where they produced movements parts sold 50 batz each. This year Rudis Sylva is proud to present the RS 23 Harmonious Oscillator.
