Tourbillon "Grand Cage" - 21B805CW

Constantin Weisz “Tourbillon”
 The tourbillon is a special device in high-quality wristwatches and pocket watches. It was invented around 1800 by Abraham Louis Breguet to compensate for the inaccuracies in the movement caused by changes in the position of a watch. In a tourbillon, the escape wheel, the anchor and the so-called balance are applied to a small plate in a rotating frame. The seconds pinion
 is located at the bottom of the bogie and is firmly connected to the lower plate. The bogie, in the middle of which the balance swings exactly above the shaft of the seconds wheel, rotates
 around the screwed-on seconds wheel. The escape wheel's drive runs on the seconds wheel. So when the seconds wheel turns once per minute, the tourbillon (the plate) follows this rotation. As a result, position or center of gravity errors no longer occur or are corrected once per minute (depending on the tourbillon). A tourbillon is still considered very difficult to build today and setting a tourbillon watch also requires a high level of expertise and care.
 The double assembly
 Our tourbillons are manufactured using what is known as a double assembly process. In the first phase, the movements are "roughly assembled" after the individual parts have been completed in order to test their functionality. The movements are then completely dismantled again and only reassembled and encased in the watch case after the individual parts have been cleaned and checked again.
