Longines GrandeVitesse Chronograph 24h
Longines created the GrandeVitesse line to embody the concept of speed through a series of models that pay tribute to the fastest men in history and are intended for the more intrepid among today’s sportsmen.

Chronograph 24h
This watch – designed for speed – is characterised by its fluid lines, its aerodynamic curves, its impressive typography, its tachymeter and the finish of its push-pieces.
And now a new model has been added to this range: the GrandeVitesse Chronograph 24h. The impressive case (diameter 44 mm) is fitted with the same L686 movement used in its sister model in the Longines Admiral line. The case features a double tachymeter on the bezel. Graduated in kph as well as MPH, it can be used for measuring ground-speeds of up to Mach 2.
The dial in a choice of black, dark brown or white with a silver sun pattern and featuring a “large 12” brings a sporty touch as well as elegance to the model. This sporty aspect is emphasised by the non-slip surface of the crown, the caseband and the push-pieces. The latest addition to the GrandeVitesse line is available on a steel bracelet with a triple folding safety clasp or a black or dark brown leather strap lined with alcantara and fitted with a folding clasp.
