In the tourbillon, the rate-governing parts \u2013 the balance and escapement assemblies \u2013 were integrated in a cage that rotated about the fourth wheel. This neutralised the position error caused by the pull of gravity on the balance wheel which can never be poised with absolute perfection, resulting in greater rate accuracy. In modern wristwatches that are worn in constantly changing orientations, the need for rate corrections is no longer a significant issue.

They decided against the option of stopping the entire tourbillon cage mechanically from within the movement. With this rather simple approach, the balance wheel would slow down and eventually coast to a halt. It would need to be \u201ckick-started\u201d to resume its reciprocating motion. This unsatisfactory approach was rejected. To preserve the potential energy of the balance spring during the braking process, the only viable alternative was to directly and instantaneously brake the balance wheel inside the cage itself.

Their solution in brief: pulling the crown initiates a complex linkage motion that causes a stop lever with two bent, V-shaped spring arms to contact the outer rim of the balance wheel, stopping it immediately. This intervention could potentially be foiled when one arm of the V-shaped braking spring happens to land on one of the three posts of the tourbillon cage. For this reason, the delicate two-armed steel spring is hinged at a rotation point of the brake lever.

Their special geometry assures that the contact pressure they exert is optimised in all conceivable positions of the brake spring relative to the balance wheel.

DESCRIPTION
- Progress through Standstill: the CABARET TOURBILLON
The tourbillon was invented more than 200 years ago. It has lost none of its fascination since then. A. Lange & Söhne has just written a new chapter in the history of the “whirlwind” with the new CABARET TOURBILLON and the first stop-seconds feature ever implemented in a tourbillon calibre.
In 1997, the CABARET amazed the world with its elegant rectangular shape that evoked the luxury, charisma, and perfection of the Art Deco epoch. Eleven years after the launch of its predecessor, the CABARET TOURBILLON by A. Lange & Söhne now sets the stage for a world debut starring the balance in a rotating carriage. For the first time ever, the “whirlwind” – the literal translation of tourbillon – has been tamed with a stop-seconds mechanism. But first things first.
