Haute Horlogerie, Opera One

A watch combining two of the most distinguished and complex complications: the minute repeater and the Tourbillon.

As an additional sophistication, the minute repeater function chimes with a “Westminster” carillon based on the use of four different gongs. The absence of dial allows a view of three of the four chime hammers in action.
