Centigraph Souverain

36,000 KM/H AT YOUR FINGERTIPS THE ART TO CONVERT 6KM/H IN 36.000KM/H

François-Paul Journe’s spectacular new watch, the Centigraphe Souverain, is a mechanical chronograph unlike any other that has ever been made before.

The hand-wound mechanical movement of the Centigraphe indicates elapsed times from a 100th of a second to 10 minutes, visible on 3 dials, each with a time scale in red and a tachometer scale in black. The tachometer scales convert time units for 1 kilometre into speeds ranging from 6 km/h —walking pace — to 36,000 km/h, well above the escape velocity of a rocket going into lowlevel orbit.

The indications The 100th of a second hand revolves around the dial in one second on a scale marked in hundredths of a second. Theoretically it is possible to time an object moving at 36,000 km/h with the tachometer on the watch face, on which 36’000 is facing the 10 on the 100th of a second scale. On the dial at 2 o’clock, the hand revolves once every 20 seconds on a time scale divided into seconds.
