BOVET Tourbillon Gande Date with 5-day Power Reserve and Reversed Hands-fitting

Introduced in 2012 as a part of Bovet’s Grandes Complications collection, the Tourbillon Gande Date with 5-day power reserve and reversed hands-fitting.

This exceptional timepiece has been developed and produced by DIMIER 1738 Manufacture de Haute Horlogerie Artisanale. Specialising in the design, manufacture, assembly and timing of tourbillons, the master watchmakers of DIMIER 1738 never tire of developing this complication, which here breaks new ground in terms of performance and aesthetic refinement.

Invented in the 18th century in the era of the pocket watch, the tourbillon is designed to counter the effects  of  the  earth’s  gravitation  on  timing  when  the  watch  is  positioned  vertically.  The  Amadeo ® case  housing  this  Tourbillon Grande Date model – and indeed the entire Fleurier collection – allows the timepiece to be converted  to a reversible wristwatch, a miniature table clock, a pocket watch or into a reversed wristwatch through simple  manipulations requiring no tools whatsoever. The Amadeo® concept therefore more than ever justifies the use of  a regulating organ driven by a tourbillon cage.

The upper pivot of the tourbillon carries a triple seconds-hand that ensures the latter’s dynamic equilibrium. This hand completes the indication of hours and minutes offset at 12 o’clock.  A balanced array of information is shown on the dial showing the magnificent big date mechanism revealed in a generous circular aperture at 6 o’clock.

The other face of the timepiece reveals the entire movement, in the centre of which can be seen the reversed hands-fitting. This face also shows the power reserve indicator with its convenient five-day duration. The striking feature of this Tourbillon is that it presents a combination of several grand complications in the guise of a simple, comfortable and reliable timepiece that collectors will undoubtedly appreciate.
