A 24-hour Chronograph to celebrate the race of the century

Singer has become globally renowned for bespoke restorations of Porsche 911 sports cars – each carried out on behalf of the car’s owner. For the Hertz Team Jota new Porsche 963, Singer has designed a unique race livery that celebrates the centenary year of the 24 Hours of Le Mans and a golden age of endurance racing.

For the occasion, the award-winning, signature central chronograph movement, the Agengraphe, has been further developed to enable a dedicated 24-hour chrono function, making this watch the perfect chronometric tool for the most prestigious endurance races.

The watch’s lightweight titanium case is inspired by the use of titanium in the race car. The smooth golden ZRN coating of the case and the black details (bezel, winding crown and push buttons) complements the car’s livery.

The latest addition to the Track1 family features a new dial layout displaying an extra central scale for 24 hours chrono indications in addition to the outer one for minutes and seconds. The engraved checkers pattern and the applied three dimensional SINGER logo make the dial even more distinctive within Singer chronographs collection.

Time of day is shown by the constantly rotating ceramic discs in white, at the edge of the watch. The outermost disc marks the hours, while the inner discs indicated minutes past the hour. The two rotating discs are executed in Singer Racing White ceramic. A world premiere.

The Singer Track1 Endurance Edition chronograph will be available for preorder starting on May 22nd 2023.

The engine under the bonnet

The AgenGraphe caliber powering the Singer Track1 stands apart from all previous chronograph movements. A decade in development, this groundbreaking piece of mechanical ingenuity redefines fundamental principles that have remained unchanged for decades.

The underlying idea that led to the invention of the AgenGraphe was to enhance the legibility of the chronograph – which is usually poor – with the use of small counters spread out across the dial. Thanks to a radically new architecture, the AgenGraphe brings together all the chronograph functions in the center of the watch, allowing for an easy and intuitive reading of elapsed time. To further enhance legibility, the chronograph incorporates jumping minute and hour indicators.

To connect the chronograph mechanism to the timekeeping gear train, the AgenGraphe features an innovative clutch mechanism. The coupling is made horizontally which requires less space, yet it is made using friction, just like a vertical clutch.

The dial-side rotor (made possible because the hands are on a central axis) leaves an unimpeded view of the movement and its 477 meticulously hand-finished parts.
