Rudis Sylva: presenting the RS12 Grand Art Horloger
Rudis Sylva is proud to present the RS12 Grand Art Horloger, the third generation of timepieces equipped with the Harmonious Oscillator and decorated in the most exquisite fashion.
This revolutionary regulator featuring two toothed balances is a unique invention minimising the effects of gravity while boasting highly sophisticated decorative details hand-worked by the region's finest craftsmen. Its technical characteristics are also exceptional:
- The two toothed balances are interlinked. This link ensures the same amplitude. The symmetry and energy of the balance springs are constantly opposed, enabling instantaneous average correction in the vertical position, which minimises the effect of gravity.
- The cage turns 360 degrees in 60 seconds
- The pallet fork is positioned at 90 degrees
- The double barrel ensures a power reserve of 70 hours
- The frequency is 21,600 vibrations/hour (3 Hz)
Seconds indicator bridge
Machined from titanium and hand-bevelled, this bridge at 6 o’clock includes no fewer than 28 internal angles. It takes 10 times longer to create a sharp internal angle in titanium than a rounded corner in steel.
The lower part of this strategic component features a hand-crafted guilloche decoration of tapering pyramids. From the edge to the centre of the piece, each guilloche line includes 60 pyramids, each one smaller than its neighbour, requiring extremely meticulous guilloche operations.
Apparent in the marking on the double barrel bridge or the caseback sundial and inscription, the extremely precise engraving magnifies the skill of the hand-engraver whose painstaking work is carried out under microscope.
Silica stones are crushed by hand and mixed with water. The resulting material is then applied to the hand-engraved surfaces and placed in a special oven at 840°C. The resulting enamel is then polished to obtain the perfect dial.
The unique technology offered by Rudis Sylva positions the Harmonious Oscillator above most existing tourbillons, since the effects of gravity to which it is subjected are minimised. The hand-finishing makes each piece unique and pays tribute to the various branches of watchmaking artistry.
