The Manufacture from Le Locle, Switzerland highlights this prestigious sporting past through the 50's Presidents' Chronograph Heritage, a re-edition of the vintage model in a contemporary 42 mm size. Echoing the graphic design of the original dial, the font used is also the same as on the historical model, especially for the logo and the numerals. In addition to the minute circle around its circumference, the dial is enlivened by a pulsometric scale underscored by the inscription “Gradué pour 30 pulsations” (graduated for 30 heartbeats). The legend “chronograph” appears below the Vulcain name at 12 o'clock, thereby specifying this chronograph's undisputed vocation for excellence.
