Conical Tourbillon


Limited edition of 8

Celebrating a Decade of Revolution in Watchmaking

Inspired by Walter Prendel's 1928 inclined balance tourbillon.
A mesmerizing blend of science and watchmaking artistry.
The independent Swiss watchmaker has developed a very personal approach to the art of watchmaking, guided by the ambition to return to the very sources of timekeeping as they were first established many thousands of years ago.
701 TC calibre hand-wound movement, which beats at 21,600 vib/h (3 Hz).
The piece symbolises a contemporary approach to watch design perfectly combined with the most refined work of the Swiss watchmaking sector’s master craftsmen.
