Open gear mechanism
This feature is a play on the Regulator theme, placing it front and center on the dial. With the “Open Gear” design, the dial is simultaneously the module board, onto which the train wheel bridges of the skeletonized gears are mounted.
Retrograde seconds
Instead of a small seconds display, this timepiece features retrograde seconds on a 30 seconds scale. It´s fun to watch the seconds hand on its journey and flying all the way back.
MAKING OF
Montres-bracelets mécaniques uniques
Museum piece
One of the assets of our Atelier Lucerne is this treasure, a hand-operated rose engine dating back to 1924 and boasting origins in the Swiss city La Chaux-de-Fonds. It takes a centuries-old technique and specialised expertise of qualified maitres d´arts to decorate dials with guilloche designs
Cutting edge
The complicated procedure, nowadays only mastered by few, brings with it an amazing variety of shapes and expressions. Applying new, yet classic guilloché patterns to cases, dials, components and rotors requires the artists to master a hand-operated rose engine.
Persistence wanted
The guilloché artisan moves the dial against the graver tool, which applies the cut, engraving the patterns about a tenth of a millimeter into the dial. The individual lines are only about two-tenths of a millimeter, making for very filigreed embellishment.
Modern Mechanical at its best
For this special edition, every single dial has been painstakingly guilloched by hand in the Atelier Lucerne.
