Matt and refined with vintage style: Instrument de Vitesse presents the purest expression of a chronograph, with no sub-counters. The collection sets the tone with its Indianapolis blue and Silverstone grey dials. Its finely printed tachymeter scale is dedicated to speed and is as functional as a dashboard instrument. Instrument de Vitesse is housed in a 39 mm diameter steel case measuring just 9.27 mm thick. It features a dial divided into two functional zones. The first, peripheral zone presents the tachymeter scale, graduated from 60 to 500 (km/h) with a base metric of 1,000 (typically one kilometre). The second, immediately adjacent zone is dedicated to the time display, with a graduated minutes circle.
