One-off piece in 750/000 white gold. The brown dial is made of solid silver. Arabic numerals and hands handcrafted in the manufactory harmonise with this. The instrumental character of the BENU Tourbillon Brown is accentuated by the finely divided minute scale. The hours and minutes can also be read accurately on two separate dials. An opening at 6 o'clock reveals Grossmann’s unusually large, flying three-minute tourbillon.

The area between 25 and 30 minutes left by the tourbillon cut-out can be precisely read thanks to the extension of the minute hand on an opposite scale (patented). Additional special features include the flying tourbillon cage with V-shaped balance bridge and the special second stop with a brush made of human hair to stop the balance (patent pending).
