The Tourbillon, a sophisticated and complex device, was invented in the late 18th century by the father of modern watchmaking, Abraham-Louis Breguet who later patented it in 1801. With this innovation, he succeeded in improving the precision of pocket watches by offsetting the advances and delays resulting from the effects of the force of gravity. By rotating on its axis at the speed of one complete revolution per minute, the device automatically compensates for possible delays or advances that might be generated by the imbalance of a balance.
The Manual Mechanical Chronograph
The DG 23.03 caliber is a Swiss-made mechanical chronograph offering excellent performance. The Tourbillon, a device that compensates for tiny variations in precision, assures a certified accuracy of +/- 4 seconds per day. The “Column” wheel used for the activation of the chronograph, is considered by experts to be the best mechanical system for the activation of a chronograph, compared to the “rocking” system typically used. Thanks to the design of the new “barrel and spring” engine, the power reserve totals approximately 100 hours.
